Did you know that petroleum motor oil only has a film strength of about 400 psi where AMSOIL has a film strength of 3300 psi and does not break down, shear or loose viscosity under heat and stress? Petroleum motor oil breaks down under heat and stress and leaves carbon, varnish and sludge deposits in your engine and allows your critical engine components to wear much more rapidly. It's no wonder you have to change it every 3000 miles and your local quick lube or auto dealer can't wait to see you again to charge you more of your hard earned money!

In a recent Lubricants World Magazine interview the president of Jiffy Lube International (owned by Penzoil- Quaker State), Marc Graham states that if they can get customers to shorten their drain intervals by 100 miles it would mean an additional $20 million in revenue for the company per year and if they can get consumers to do one more oil change per year it would mean $294 million for the oil change alone and $441 million in revenue when they include ancillary products and services that go along with the oil change. In fact, Graham openly admits that the bottom line is profits. The shorter the drain interval the more money Jiffy Lube and Penzoil-Quaker State make. With statements like this it sure appears that they apparently don't care about your vehicle and selling you a quality extended drain interval synthetic, like AMSOIL. All they want is to see the same customer over and over again as often as possible!

How Does AMSOIL Compare Against Other Major Oil Brands Synthetics?

There is not a single one that even comes close to providing the wear protection that AMSOIL does! Just look at the graphs on the back of AMSOIL's Series 2000 20W-50 Racing Oil or the Series 2000 0W-30 Severe Service Oil.

The 20W-50 Mobil 1 Tri-Synthetic leaves a wear scar over 2 times that of the AMSOIL (0.440 mm for AMSOIL vs. 0.922 mm for Mobil 1)!

Same thing goes for Havoline Formula 3 (0.713), Valvoline Synthetic (0.741), Castrol Syntec (0.757), Quaker State (0.790, synthetic blend).

The Mobil 1 Tri-Synthetic 0W-30 leaves a wear scar over 1.6 times that of the AMSOIL 0W-30 (0.373 for AMSOIL and 0.607 for Mobil 1)!

Same thing goes for Penzoil 5W-30 at 0.540, Castrol Syntec 5W-50 at 0.576, Mobil 1 5W-30 at 0.589 and Quaker State 4x4 10W-30 Synthetic Blend at 0.595.
--------------------------------------------------------------------------------------
We now have the independent lab test data for the new Mobil Supersyn. The Supersyn does not compare to AMSOIL's extended drain interval 25,000 mile/1-year or 35,000 mile/1-year oil (0W-30). The test data is as follows for AMSOIL 5W-30 vs. Mobil Supersyn 5W-30:

NOACK Volatility: AMSOIL: 4.90%, Supersyn: 9.17%

Flash Point: AMSOIL: 446 deg. F., Supersyn: 435 deg. F.

Fire Point: AMSOIL: 471 deg. F., Supersyn: 455 deg. F.

Pour Point: AMSOIL: - 60 deg. F, Supersyn: -54 deg. F

4-Ball Wear Test: AMSOIL 0.40 mm, Supersyn: 0.60 mm

TBN (Total Base No.): AMSOIL 12.35, Supersyn 8.45

Mobil will not recommend or guarantee 25,000 mile/1-year drain intervals like AMSOIL 5W-30, 10W-30 or 10W-40 or 35,000 mile/1-year drain intervals like AMSOIL 0W-30 Severe Service Synthetic does and that is a fact. No-where on the Mobil bottle does it state 25,000 miles/1-year or 35,000 miles/1-year.

 

CASTROL AND MOBIL GO TO COURT TO BATTLE IT OUT:

Recently, Mobil accused Castrol of reformulating its synthetic by substituting other basestocks in place of its synthetic polyaphaolefins (PAO's). Castrol Syntec is a hydrocracked oil. That's right, Castrol has replaced the PAO synthetic base stock with hydroisomerized petroleum base stock. Hydrocracking, as it's called, is the highest level of petroleum refining. Castrol isn't even a true synthetic yet Castrol ended up winning the battle when the National Advertising Division of the Council of Better Business Bureaus ruled that Castrol could still market its oil as "synthetic" despite their new formulation. Basically, they expanded the definition of synthetics to include Group III hydroprocessed petroleum oil. This high profile case took place because synthetics are recognized as the market's best hope for growth. Synthetic oil sales have outpaced petroleum oil sales by a wide margin and the gap continues to widen every year. Consumers are getting smarter and demand the best for their vehicles! Read the full story on the Castrol debacle in our informative articles section. Additionally, just as soon as Castrol won this battle, several other major oil companies jumped in and came up with hydroprocessed motor oils of their own and labeled these products to be "100% synthetic", when they still are primarly Group III hydroprocessed petroleum oils!

 

Since 1972, AMSOIL Synthetics have proven to be the BEST.AMSOIL also engineers and manufactures Super Duty Oil filters which have a 12,500 mile service life as well as specialized filtration systems for commercial and fleet applications in cars and light, medium and heavy trucks which can filter particles down to less than one micron ( a standard full flow oil filter can only filter to 20-25 microns with any degree of efficiency) making oil changes virtually unnecessary and virtually eliminating engine wear. These filters have been proven by millions of miles of over-the road trucks, construction equipment and fleet service.

Here is some info regarding oil color.

Oil Color, Lubrication Ability and Contamination Level

AMSOIL Synthetic Lubricants are designed and engineered for extended drain interval service. The color the AMSOIL on your dipstick (or ANY oil for that matter) has absolutely no bearing on whether or not the oil is suitable for continued use or if it should be drained and replaced. Use the recommended change intervals for both the oil and engine oil filters as specified by AMSOIL.

It is a common misconception that an oil's color is an indication of how dirty it is. This is absolutely NOT TRUE. The color of an oil does not have any bearing on its lubrication ability. Most oil and especially diesel engine oil will turn black in the first few hours of operation due to contaminates generated by the combustion process and soot particles. The ONLY way to accurately determine an oil's lubricating value or contamination level is through (spectrographic) oil analysis. Oil analysis is common practice used regularly in commercial, industrial and fleet operations and can also be used for passenger cars, light trucks or any other application. In addition oil analysis will also determine the exact pars per million (ppm) of wear metals in your oil which provides an indication of any abnormal wear or specific components that need mechanical inspection in addition to checking for any fuel, water or glycol contamination. *At the end of this section you will find a listing of what oil analysis testing checks for.

The useful life of an engine oil is dependent on several factors such as the quality of the oil, type of fuel, equipment condition, type and operating environment of the equipment and, most important, the type of filtration used. The filtration system and the oil are vital tools for preserving engine life. A highly efficient filter is essential to protect an engine by removing both liquid and abrasive contaminants held in suspension by a high quality premium oil such as AMSOIL. When using AMSOIL Synthetic Lubricants for extended drain intervals the AMSOIL Super Duty Filter must be changed at 12,500 miles or 6 months for gas engines and 10,000 miles or 6 months for diesel engines, such as the Ford Powerstroke or Dodge Cummins.

If the AMSOIL Dual-Gard or Dual-Remote By-Pass Filtration Systems are used then the AMSOIL Super Duty full flow engine oil filter must be changed at the same intervals as specified above and the by-pass filter(s) changed as indicated by oil analysis results. The oil does not need to be changed when using by-pass filtration unless oil analysis testing indicates it is necessary.

It is not uncommon to get several hundred thousand or more miles on the AMSOIL when using by-pass filtration. A Mack Dealership recently performed a teardown inspection on a 1990 Mack E7-400 diesel engine with 630,000 miles total and 409,000 miles without an oil change and its parts were examined by an engine rater from a major oil additive raw materials manufacturer and supplier. The engine showed light to moderate wear throughout, just as an engine in similar service and lubricated with conventional oil changed at 15,000-20,000- mile intervals (as is common with over-the-road semi-trucks) would show. In fact, according to the engine rater the parts examined- cylinder liners, pistons, rings, bearings, valve train components- could have been put right back in the engine and would have continued to provide the good, dependable service they had provided all along- after 409,000 miles without an oil change! If you would like the full detailed report and photographs of this teardown inspection please e-mail us your address and we will drop it in the mail.
