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.

Does Your Differential Feel Neglected? Synthetic Gear Oil

Does Your Differential Feel Neglected? Change to synthetic gear oil

Free Amsoil Catalog

Many truck and SUV owners personalize their vehicles with aftermarket products such as lift kits, tires and rims, custom grills, paint, wheel well flairs and engine upgrades. While these upgrades and accessories can increase engine performance and add plenty of visual appeal, they do nothing for extending drivetrain life like synthetic gear oil can do.  Most people perform proper engine maintenance and change their engine oil on a regular basis, but according to one quick lube business, only about two percent of its customers purchase differential gear lube changes. Even fewer change to synthetic gear oil. Sometimes this out of sight, out of mind differential neglect results in costly gear failure, leaving the motorist stranded on the highway.

synthetic gear oil

differential drain plug

There are two basic ways to change differential gear lube to synthetic gear oil. The old fluid may be drained or suctioned out and the differential refilled with new gear lube, or the differential cover may be removed to allow more of the old gear lube to drain out and allow access to the magnet inside the differential. Unlike engines, differentials are not equipped with filters. Instead, magnets that are open to the entire gear lube sump are used to catch some of the metal wear particles. When changing differential fluid, the magnet should be cleaned to ensure the new gear lube does not
become contaminated.

After draining the old fluid and cleaning the magnet, the differential cover should be re-installed and the differential filled with the correct viscosity grade of AMSOIL SEVERE GEAR® Synthetic Gear Lube. The use of cleaning solvents is not recommended. Initial differential oil changes are recommended by some manufacturers after the first 500 to
3,000 miles. synthetic gear oil

synthetic gear oil

Even when vehicle manufacturers do not specify to change the factory-fill gear lube to remove wear particles, it is a
good practice to do so. For optimum gear and bearing life, AMSOIL recommends the factory-fill differential gear lube
be changed no later than the first 5,000 miles with new or rebuilt gears, followed by 50,000 mile drain intervals in
severe service or 100,000 mile drain intervals in normal service when using AMSOIL synthetic gear lubes.

AMSOIL recommends any one of three SEVERE GEAR viscosity grades, 75W-90, 75W-110 or 75W-140, for turbo diesel or 4×4 trucks, SUV’s and automobiles.

SEVERE GEAR 75W-90 (SVG) replaces competitive 75W-90 and
80W-90 gear lubricants and delivers the optimum fuel efficiency and cold temperature performance of all the SEVERE GEAR gear lubes.

SEVERE GEAR 75W-110 (SVT) replaces competitive 75W-110, 75W-90 and 80W-90 gear lubricants and delivers increased fluid film wear protection over lighter viscosity fluids and better fuel efficiency than 75W-140 gear lubes.

SEVERE GEAR 75W-140 (SVO) replaces competitive 75W-140, 80W-140 and 85W-140 gear lubes in applications where these viscosities are recommended by equipment manufacturers.

Also don’t forget to look at the RACING gear oil options.

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.
