Best Performance Motor Oil?
API Comparative Motor Oil Testing
AMSOIL Synthetic 10W-30 Motor Oil (ATM) and 10 competing conventional and synthetic 10W-30 motor oils were subjected to a series of API motor oil tests. The competing oils included petroleum-based Castro GTX Drive Hard, Mobil Drive Clean, Pennzoil with Purebase, Quaker State Peak Performance and Valvoline, as well as synthetic-based Valvoline Synpower, Quaker State, Castrol Syntec, Pennzoil and Mobil SuperSyn Multi-Vehicle.
Seven API tests were run on the motor oils. The Thin-Film Oxygen Uptake Test (TFOUT) measures the oxidation stability of engine oils. The High Temperature/High Shear Test (HTHS) measures a lubricant's viscosity under severe operating conditions. The NOACK Volatility Test measures the evaporation loss of oils in high temperature service. Pour Point indicates the lowest temperature at which a fluid will flow. Total Base Number (TBN) is the measurement of a lubricant's reserve alkalinity for combating acids. The Cold Cranking Simulator Test (CCS) measures a lubricant's viscosity at low temperatures and high shear rates. The Four-Ball Wear Test measures a lubricant's wear protection properties. The impressive test results show AMSOIL Synthetic 10W-30 Motor Oil outperformed the competitors in each test.
Thin-Film Oxygen Uptake (ASTMD-4742)
The Thin-Film Oxygen Uptake Test evaluates the oxidation stability of lubricating oils. A mixture of the test oil and chemistries found in gasoline engine operation (oxidized/nitrated fuel, soluble metals and distilled water) are placed in a test vessel, which is pressurized with oxygen and placed in a heated bath. Anti-oxidant breakdown is evident when the oxygen pressure in the vessel rapidly decreases. At this point, the induction time (break point) of the oil is recorded. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil had the highest induction time of all the tested oils. In fact, it didn't reach its break point in over 500 minutes of testing.
The superior oxidation stability of AMSOIL Synthetic 10W-30 Motor Oil allows it to effectively resist the formation of engine deposits and sludge, keeping engines running clean and efficient and extending oil life. It also resists thickening, maintaining its superior wear protection and lubricating properties and maximizing fuel efficiency.
High Temperature/High Shear (ASTM D-4683)
The High Temperature/High Shear Test measures a lubricant's viscosity under severe hightemperature and shear conditions that resemble highly-loaded journal bearings in fired internal combustion engines. In order to prevent bearing wear, it is important for a lubricant to maintain its protective viscosity under severe operating conditions. The minimum High Temperature/High Shear viscosity for a 30 weight oil is 2.9 cP. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil surpasses this minimum standard and displayed the highest High Temperature/High Shear viscosity in the group.
The superior viscosity retention of AMSOIL Synthetic 10W-30 Motor Oil in the face of severe temperature and shear conditions allows it to provide continuous, unsurpassed protection for engine bearings, extending equipment life and preventing wear.
NOACK Volatility (ASTM D-5800)
The NOACK Volatility Test determines the evaporation loss of lubricants in high temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear and emissions. A maximum of 15 percent evaporation loss is allowable to meet API SL and ILSAC GF-3 specifications. As shown in the graph, AMSOIL 10W-30 Synthetic Motor Oil outperformed its nearest competitor by over 30 percent.
The extremely low volatility of AMSOIL Synthetic 10W-30 Motor Oil allows it to maintain its superior protective and performance qualities throughout extended drain intervals, even when faced with severe operating temperatures. In addition, oil consumption and emissions are minimized and fuel efficiency is maximized.
Pour Point (ASTM D-97)
The Pour Point Test determines the lowest temperature at which a lubricant will flow when cooled under prescribed conditions. The lower a lubricant's pour point, the better protection it provides in low temperature service. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil has the lowest pour point of the tested oils.
The low pour point of AMSOIL 10W-30 Synthetic Motor Oil allows it to maintain its fluidity in extremely low temperatures, reducing drag on moving vehicle parts, providing critical engine components with quick, essential lubrication and easing startup in cold temperatures. Wear is greatly reduced and equipment life is extended.
Total Base Number (ASTM D-2896)
Total Base Number (TBN) is the measurement of a lubricant's reserve alkalinity, which aids in the control of acids formed during the combustion process. The higher a motor oil's TBN, the more effective it is in suspending wear-causing contaminants and reducing the corrosive effects of acids over an extended period of time. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil has the highest TBN of the tested oils.
The high TBN of AMSOIL Synthetic 10W-30 Motor Oil allows it to effectively combat wear-causing contaminants and acids, providing superior protection and performance over extended drain intervals.
Cold Crank Simulator (ASTM D-5293)
The Cold Crank Simulator Test determines the apparent viscosity of lubricants at low temperatures and high shear rates. Viscosity of lubricants under these conditions is directly related to engine cranking and startability. The lower a lubricant's cold crank viscosity, the easier an engine will turn over in cold temperatures. 10W motor oils are tested at -25°C and must have a viscosity below 7000 cP to pass. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil is well below the maximum requirement, while many of the competing oils barely pass.
The low cold crank viscosity of AMSOIL Synthetic 10W-30 Motor Oil reduces drag on moving engine parts and allows engines to achieve critical cranking speed in extremely frigid temperatures. Engines turn over quickly and dependably in the coldest winter temperatures.
Four Ball Wear (ASTM D-4172)
The Four Ball Wear Test determines the wear protection properties of a lubricant. Three metal balls are clamped together and covered with the test lubricant, while a rotating fourth ball is pressed against them in sliding contact. This contact typically produces a wear scar, which is measured and recorded. The smaller the average wear scar, the better the wear protection provided by the lubricant. As shown in the graph, AMSOIL Synthetic 10W-30 Motor Oil produced the smallest wear scar of the tested lubricants.
AMSOIL Synthetic 10W-30 Motor Oil provides unsurpassed protection against engine wear. Equipment life is extended, and repairs, downtime and expenses are reduced.
AMSOIL INC.has been the leader in synthetic motor oil formulationsince its introduction of the world's first API rated synthetic motor oil in 1972. By specializing exclusively in the synthetic lubricant technology, AMSOIL is able to optimize the most advanced chemistries available. The "Genuine Synthetic PAO Formulated" designation displayed on AMSOIL packaging indicates that the oils are formulated with Polyalphaolefin (PAO) synthetic base stocks. This chemistry is the industry's premier base stock technology. Unlike conventional mineral-based chemistries, AMSOIL PAO base stocks contain fullysaturated, hydrogenated molecules and are free of wax and other impurities. Combined with an exact balance of premium additives, itdelivers superior hot and cold temperature performance, resists oxidation and acid formation and provides long-term wear protection. AMSOIL "General Synthetic PAO Formulated" oils have shattered the parameters of the most rigorous industry testing and set the standard for all other motor oils.

REDUCE OUR DEPENDENCE ON FOREIGN OIL WITH AMSOIL
AMSOIL has 30+ years of oil analysis data showing their oils provide extended interval drain service capabilities. Big oil companies can't argue with that data or explain it away. They would prefer that you "buy into the myth" of 3k mile oil changes because it adds profits to their bottom line.
AMSOIL offers extended drain intervals because we start with superior base oils and and the additive package is properly balanced, blended, and capable of performing for extended drains.
Now the entire industry is moving in that direction. It has been published that automotive manufacturers will be recommending extended drain intervals of up to 15,000 miles in the near future (they already are in Europe) ... because that's what consumers want.
Amsoil's Extended Oil Drain Interval: It is the right thing to do for the consumer, for the environment, and a way to reduce american dependence on foreign oil.
Longer Drain Intervals = less oil used.

REDUCE OUR DEPENDENCE ON FOREIGN OIL WITH AMSOIL
Industry tests have shown improved fuel economy of 2 - 5% in vehicles using synthetic lubricants. Many AMSOIL customer testimonials tell of even greater savings. If all cars in America used AMSOIL synthetic motor oil, gear lubes and drive train fluids, we would save enough fuel to eliminate our need for thousands of barrels of oil.
As mentioned earlier, there is another way to reduce oil usage. AMSOIL synthetic motor oils are designed for extended drain intervals and reduce the amount of oil used by as much as 80%.
Fewer oil changes means less oil used.

I run what my father does. Is it the best I have no idea, I just no it works and has worked brand wise. I have heard nothing bad about AMSOIL. I do not run it because no I know does word of mouth, has yet to reach me. Synthetic is 100% better in the write engine. Be careful. Running it in an older vehicle could possible cause it to leak. My understanding is the molecules are smaller. Not because the oil is bad. I ran synthetic one time in my 80 20r engine Toyota and it leaked like a sieve switched back to dyno per my mechanic no leaks. I run Mobil in my 04 dak pure synthetic and It runs well. Any more power I have no Idea shave any time off my quarter mile probably not. Better all around oil performance in regards to breakdown, yep. According to my mechanic some engines like it better and some do not.
