When is It Hot Enough for a Synthetic Oil?

When is It Hot Enough for a Synthetic Oil?

Synthetic Oil

Synthetic Oil

“My supplier is pushing hard to move his synthetic gear oils into my operation. His position is that the units run too hot for long-term use of mineral oils. At what temperature should I switch to a Synthetic Oil lubricant for a non-circulated gearbox?”

First, the term synthetic is very broad, so we assume you are referring to lubricants that are formulated using polyalphaolefin (PAO) synthetic oil base.

Synthetic Oil

There is no single temperature point that dictates a time to move to synthetics. The decision is dependent on equipment continuous loads and shock loads, equipment availability for routine maintenance, criticality of the application, component life cycles, lubricant life cycles and failure modes among other things.

Generally, the rate of lubricant degradation doubles with every 18 degrees F increase in temperature. Once formulated with antioxidant additives, PAO-based lubricants have a lower baseline rate of oxidative degradation. At low temperatures, a PAO’s increased oxidative life may not be noticeable, particularly if you have to change the oil at some point for other reasons. At higher temperatures, the synthetic may last noticeably longer.

Typically, you begin to notice the extra life provided by a PAO synthetic oil above 160 degrees F. If it is above 180 degrees F, and especially 200 degrees F, the difference in oxidative life becomes quite apparent. However, the point at which a change to synthetic is justified is dependent perhaps on a handful of additional “program management” parameters such as:

1. Do you intend to run your gear oils with an appropriate use of filtration and oil analysis to support life-cycle extensions for many years?

2. Are you currently doing oil analysis and performing condition-based changes?

3. Do you have, and have you communicated to your lab, oxidation limits that flag impending oxidation problems?

4. Does the machine’s operating temperature vary a great deal (a PAO’s high viscosity index enables it to operate across a wider temperature range)?

5. Do you have an effective contamination control program in place that will enable you to fully exploit the PAO’s extended life?

With the appropriate management strategy, a change to a high-performance product can actually cost considerably less than the equivalent mineral oil product type. Outside of these considerations, somewhere around 165 degrees F represents the point at which you probably should begin to consider the use of synthetics for the sake of lubricant longevity, if not for the sake of reliability.

Family Handyman Magazine Gets it Right on Synthetic Oil Myths – almost : Amsoil Engine Flush.

Amsoil Engine Flush

Family Handyman magazine

Family Handyman Magazine had a short tip on the 4 Big Synthetic Oil Myths. www.familyhandyman.com

The big four myths listed were;

  1. You have to flush the engine before you can run synthetic oil in it. FALSE. You should NEVER flush your engine. All carmakers warn against this practice. (editorial comment; this is the one reaction we disagree with)
  2. Synthetic oil causes leaks. FALSE. This was true 25 years ago. Not anymore. Current formulations contain seal conditioners to prevent leaks.
  3. Once you switch to synthetic, you can’t go back to regular oil. FALSE. No truth whatsoever to this one.
  4. Since synthetic oil flows better when cold, I can ignore the manufacturer’s recommendations for 5W- 20 and use 10W-30. FALSE. Heavier weight oil reduces fuel efficiency and can mess up valve timing mechanisms. Stick with the manufacturer’s oil weight recommendations.

Amsoil Engine Flush

In general, Family Handyman gets it straight on these tips. These have each been a long standing myth so it’s good to get a major magazine to clear the air. We agree with their reaction to tips 2,3, and 4.

Engine Flush

Amsoil has sold an engine flush product for years. In many cases, it’s not needed. However, in certain cases it’s a proper product to use to transition a car to synthetic oil. It’s been used in thousands of vehicles by thousands of Amsoil customers with no issues.

Amsoil Engine Flush

Amsoil Engine Flush AMSOIL Engine and Transmission Flush (FLSH) helps restore fuel economy, increase operating efficiency and reduce emissions in gasoline and diesel engines, and automatic transmissions. Its potent, detergent-based formula cleans sludge and deposit build-up, promoting lower operating temperatures and reduced oil consumption. AMSOIL Engine and Transmission Flush is safe on parts and can be easily disposed of with waste oil. Amsoil Engine Flush

Restores Vehicles to Like-New
New engines and transmissions run more efficiently, but over time they gather harmful deposits that cause power and performance loss. Stop-and-go driving, prolonged idling, short trips that do not allow the engine to reach full operating temperature, towing, the ingestion of airborne dirt, fuel dilution, water condensation and oxidized oil all can promote sludge build-up in motor oil and transmission fluid. As it settles, sludge clogs narrow oil passages, restricting oil flow to vital parts, especially the upper valve train area. Amsoil Engine Flush

In transmissions, deposits can form on clutch plates, causing hesitation and erratic shifting. Ultimately clutch glazing can set in, reducing the life of the transmission. Deposits in engines and transmissions can accelerate wear, causing power loss and increased fuel consumption. Amsoil Engine Flush

• Cleans engines and transmissions for improved efficiency, fuel economy and lower emissions
• Prolongs equipment life
• Detergent-based formula more environmentally friendly
• Compatible with seals and gaskets
• One-treatment results
• Easily disposed of with waste oil

Installing new oil or transmission fluid into a dirty vehicle may not be enough to remove deposits and increase efficiency. The detergents and dispersants in some lubricants may not be able to handle leftover sludge and deposits, and the new lubricant soon becomes unfit for service, accelerating the formation of even more harmful deposits. Amsoil Engine Flush

AMSOIL Engine and Transmission Flush Benefits
Unlike many flush products, AMSOIL Engine and Transmission Flush features a multi-use formulation that dissolves and disperses sludge, varnish and deposits in both engines and automatic transmissions. Due to its detergent-based formulation, used AMSOIL FLSH can be easily disposed of with waste oil, making it more user-friendly. Its advanced formula of light base oil technology, powerful detergents and dispersants provides safe cleaning action. AMSOIL FLSH is compatible with both petroleum and synthetic oils, preparing poorly maintained equipment for installation of new oil. It represents the first step toward restoring neglected equipment to top-notch performance. AMSOIL Engine and Transmission Flush provides the following benefits in only one treatment:

Gasoline and Diesel Engines

• Helps loosen sticky valves and rings, minimizing blow-by and reducing emissions
• Helps quiet lifter noise
• Promotes lower operating temperatures through sludge removal
• Easy disposal

Automatic Transmissions

• Cleans deposits in oil cooler and ports
• Helps unclog fluid passages
• Cleans deposits and varnish from clutch plates, helping improve efficiency
• Promotes smoother operation and transmission life through reduced shift delay

Applications
AMSOIL Engine and Transmission Flush is recommended for diesel and gasoline engines, and automatic transmissions. It is not recommended for CVT transmissions or differentials.

Directions for Use
Though it works in one treatment, AMSOIL Engine and Transmission Flush is safe enough to be used at every oil change. If using a flushing machine, follow the manufacturer’s recommendation. Otherwise, use the following guidelines:

Engine: Add 16 oz. bottle of AMSOIL Engine and Transmission Flush to engine oil fill port. Idle the engine for 10-15 minutes, then immediately drain the oil. Ensure enough time for the system to completely
drain. Remove and replace the engine oil filter. Refill engine with new engine oil in the viscosity grade recommended by the manufacturer.

Transmission: Engage emergency brake. Add 16 oz. bottle of AMSOIL Engine Flush to transmission oil fill port. Idle for 10-15 minutes; shift through drive and reverse. Do NOT place vehicle under heavy load. Drain entire transmission and torque converter of fluid. FILTER MUST BE CHANGED prior to refilling with new transmission fluid.

NOTE: It is not recommended to flush transmissions that do not have a removable pan or access to the transmission filter.

Free Amsoil Catalog

synthetic compressor oil Buy Amsoil Synthetic Compressor Oil now!

Synthetic compressor oil can eliminate one maintenance chore in your shop. Most folks never change the compressor fluid in shop air compressors. These are often neglected, but critical tools in a shop. You can eliminate the need to maintain and monitor oil changes in compressors by installing synthetic compressor oil. AMSOIL PC Series Synthetic Compressor Oil is a long-life, premium compressor lubricant based on novel, proprietary technology. It incorporates the highest quality, thermally stable PAO synthetics fortified with premium non-detergent, ashless additives for maximum protection at high temperatures and pressures. It lasts up to eight times longer than petroleum oils, effectively reducing maintenance and waste oil disposal costs.

Improves Compressor Efficiency
AMSOIL PC Series Synthetic Compressor Oil has low friction properties and resists viscosity increase from oxidation. It helps improve operating efficiency and saves money on electrical energy consumption.

Synthetic Compressor Oil

synthetic compressor oilControls Foam and Reduces Wear
AMSOIL PC Series Synthetic Compressor Oil contains anti-foam additives and, unlike some other compressor oils, is anti-wear fortified. Good foam control reduces heat, oxidation and wear. High contact regions are protected against wear for increased compressor life and efficiency.

Resists Water Contamination
Water from condensation builds up in compressors and can cause unwanted oil/water emulsions, environmental discharge hazards and rust. AMSOIL PC Series Synthetic Compressor Oil is hydrolytically stable. It resists acid formation, readily separates from water and is anti-rust fortified. Water can be easily drained for simplified environmental discharge and increased oil life.

Resists Heat and Oxidation
AMSOIL PC Series Oil combines the inherent stability of premium synthetic base oils with specialized anti-oxidant additives to resist varnish, carbon and acid formation. It is formulated to protect compressors better and last longer in service than petroleum oils, especially during hot operating conditions.

Safety Advantage
AMSOIL PC Series Oil is an ashless, high-flash-point formulation with very low carbon-forming tendencies that minimizes the incidence of ignition-promoting “hot spots.” While PC Series Oil can provide improved fire safety, it cannot be considered non-flammable.

Application Recommendation
AMSOIL PC Series Oil in the appropriate viscosity is recommended for use in single and multistage rotary screw, vane, centrifugal and reciprocating compressor crankcases and cylinders, vacuum pumps and other applications such as gears, bearings, blowers, pumps and handheld pneumatic tools. In compressor applications, drain intervals of 8,000 hours or more can be expected under normal operation. Drain intervals are subject to operating conditions and maintenance practices. Monitoring by oil analysis is recommended. For best performance when converting to AMSOIL PC Series Synthetic Compressor Oil, it is recommended the compressor be drained of the old fluid prior to the installation of PC Series Oil. If carbon deposits are present on the internal components, it is recommended they be removed following the compressor manufacturer recommendations.

How to change the air compressor oil

Some air compressors are oil less; they do NOT use oil. If you have one of those, you don’t have to change oil since there isn’t any. Most large shop style tower compressors ARE oil lubricated.

  • Do NOT use regular automotive oil; this is against almost all manufacturer recommendations. Read your manual.
  • Determine the weight and spec recommended.
  • There will usually be a drain and a filler/dipstick.
  • Drain the oil, and put the plug back in.
  • Fill the oil to the level recommended on the dipstick, or on the oil sight glass.
  • Most manufacturers (including CH) recommend changing once after the first hour of use.

Two cycle Engine Applications and Lubrication

Two cycle Engine

Applications and Lubrication Needs

The best two cycle engine oil

FREE Amsoil catalog

Two cycle engines can be found nearly everywhere these days. They are used in dozens of applications and in a wide variety of designs for everything from work and recreation to power generation. two cycle engines have design differences and operate under conditions that require different oil chemistries than their four-cycle counterparts. In order to recommend a lubricant for a two-cycle engine, one needs to know how this engine operates, why it is used in place of a four-cycle engine and where and in what type of applications it is used.

Two cycle Engine

What is a two cycle engine? How do two cycle engines work?

Two cycle engine

Two cycle engine

The terms “two-cycle” and “two-stroke” are often inter-changed when speaking about two cycle engines. These engines derive their name from the amount of directional changes that the pistons make during each power stroke. Internal combustion engines are used to produce mechanical power from the chemical energy contained in hydrocarbon fuels. The power-producing part of the motor’s operating cycle starts inside the motor’s cylinders with a compression process. Following this compression, the burning of the fuel-air mixture then releases the fuel’s chemical energy and produces high-temperature, high-pressure combustion products. These gases then expand within each cylinder and transfer work to the piston. Thus, as the engine is operated continuously, mechanical power is produced. Each upward or downward movement of the piston is called a stroke. There are two commonly used internal combustion engine cycles: the two-stroke cycle (Two cycle engine) and the four-stroke cycle.

Two cycle Engine

How are two cycle engines different from four-cycle engines?

Two cycle engine

Two cycle engine

The fundamental difference between two cycle engines and four-cycle engines is in their gas exchange process, or more simply, the removal of the burned gases at the end of each expansion process and the induction of a fresh mixture for the next cycle. The two cycle engine has an expansion, or power stroke, in each cylinder during each revolution of the crankshaft. The exhaust and the charging processes occur simultaneously as the piston moves through its lowest or bottom center position.

In a four-cycle engine, the burned gasses are first displaced by the piston during an upward stroke, and then a fresh charge enters the cylinder during the following downward stroke. This means that four-cycle engines require two complete turns of the crankshaft to make a power stroke, versus the single turn necessary in a two-cycle engine. In other words, two-cycle engines operate on 360 degrees of crankshaft rotation, whereas four-cycle engines operate on 720 degrees of crankshaft rotation.

Where are two cycle engines used?

Two-cycle engines are inexpensive to build and operate when compared to four-cycle engines. They are lighter in weight and they can also produce a higher power-to-weight ratio. For these reasons, two-cycle engines are very useful in applications such as chainsaws, Weedeaters, outboards, lawnmowers and motorcycles, to name just a few. Two-cycle engines are also easier to start in cold temperatures. Part of this may be due to their design and the lack of an oil sump. This is a reason why these engines are also commonly used in snowmobiles and snow blowers.

Some advantages and disadvantages of two-cycle engines

Because two-cycle engines can effectively double the number of power strokes per unit time when compared to four-cycle engines, power output is increased. However, it does not increase by a factor of two. The outputs of two-cycle engines range from only 20 to 60 percent above those of equivalent-size four-cycle units. This lower than expected increase is a result of the poorer than ideal charging efficiency, or in other words, incomplete filling of the cylinder volume with fresh fuel and air. There is also a major disadvantage in this power transfer scenario. The higher frequency of combustion events in the two-cycle engine results in higher average heat transfer rates from the hot burned gases to the motor’s combustion chamber walls. Higher temperatures and higher thermal stresses in the cylinder head (especially on the piston crown) result. Traditional two-cycle engines are also not highly efficient because a scavenging effect allows up to 30 percent of the unburned fuel/oil mixture into the exhaust. In addition, a portion of the exhaust gas remains in the combustion chamber during the cycle. These inefficiencies contribute to the power loss when compared to four-cycle engines and explains why two-cycle engines can achieve only up to 60 percent more power.

How are two-cycle engines lubricated?

Two-cycle motors are considered total-loss type lubricating systems. Because the crankcase is part of the intake process, it cannot act as an oil sump as is found on four-cycle engines. Lubricating traditional two-cycle engines is done by mixing the oil with the fuel. The oil is burned upon combustion of the air/fuel mixture. Direct Injection engines are different because the fuel is directly injected into the combustion chamber while the oil is injected directly into the crankcase. This process is efficient because the fuel is injected after the exhaust port closes, and therefore more complete combustion of fuel occurs and more power is developed. Direct injection engines have a higher power density than traditional two-cycle engines. Because the oil is directly injected into the crankcase, less oil is necessary and lower oil consumption results (80:1 range). Direct Injection motors have higher combustion temperatures, often up to 120F. They also require more lubricity than traditional two-cycle motors.

AMSOIL Provides Complete Vehicle Cold-Weather Performance

Click here for FREE Amsoil catalog!

Amsoil

Amsoil synthetic oil works better in extreme cold. Extreme cold can cause conventional motor oil, transmission fluid and gear lube to thicken, starving vital moving parts of necessary lubrication. In many cases, thick motor oil will prevent vehicles from starting. Cold, thick transmission fluid results in delayed or sluggish shifts and inadequate protection for bearings, valves and other critical parts. Thick gear lube, meanwhile, requires more energy to turn the gears, reducing fuel efficiency. Because gears and bearings in the axle housing are splash-lubricated, conventional gear lubes that are too thick at cold temperatures can starve internal components of lubrication, which can cause excessive wear and premature failure.
Conventional petroleum lubricants thicken because they often contain paraffin (wax). While modern refining techniques remove most of the wax from petroleum oil, some wax-like molecules remain. These wax-like molecules are soluble at ambient temperatures above freezing, but crystallize into a honeycomb-like structure at lower temperatures and cause circulation problems. At startup, this can leave working parts unprotected while the lubricant warms to a temperature that allows it to flow. amsoil synthetic lubricants do not contain paraffin. Amsoil synthetic oils provide outstanding low-temperature fluidity for fast, dependable winter starts; quick, responsive shifts and immediate startup protection. Superior Amsoil Fuel & Coolant Additives and Amsoil Diesel applications can be especially sensitive to cold-weather issues. As the temperature drops, the wax naturally found in diesel fuel begins to form
crystals. The point at which wax crystals form is known as the cloud point. These wax crystals eventually clog the fuel filter and starve the engine of fuel, preventing it from starting. While low-quality fuels may form wax crystals in temperatures as warm as 40°F, most fuels have a cloud point near 32°F. The point at which the wax crystals clog the fuel filter is known as the cold filter-plugging point (CFPP). amsoil Cold Flow Improver reduces the CFPP of ultra-low-sulfur diesel fuel by as much as 20ºF for increased protection. In frigid conditions, motorists often idle vehicles for extended periods to warm the interiors and defrost the windows. Not only can the practice be inconvenient, it wastes fuel as well. amsoil Dominator® Coolant Boost uses proprietary tiered-surfactant technology to provide quick and effective heat transfer inside radiator and cylinder heads, resulting in faster engine warm-up times. As a result, vehicle interiors warm more quickly and the defroster becomes effective sooner. Amsoil diesel fuel additive. Amsoil antifreeze. Amsoil fuel addetive.
