Synthetic Oil Comparison
When motorists look for synthetic oil comparison reviews to help make an educated choice, they find that there’s precious little data available since very few synthetic oil companies are willing to put their products out for head-to-head comparisons.
AMSOIL Oil has long been quite willing to put their synthetic oils up for review and for synthetic motor oil comparison tests.

|Pennzoil Platinum||Mobil 1 Extended Performance|
|Valvoline Synpower||Quaker State Synthetic|
|Castrol GTX||Shell Formula|
|Chevron Supreme||Motorcraft Synthetic Blend|

- Cold cranking ability
- Wear control
***AMSOIL 10W-30 Synthetic Motor Oil dominated the motor oil brand comparison testing across the board.
AMSOIL Synthetic Oil Customer Reviews
In the review section at Amazon.com, AMSOIL Synthetic Motor Oil Received Rave Reviews and a rating of 4.5 stars out of 5 from customers. Here are some quotes from reviewers.
Modern Blue Argonaut said, “I really love Amsoil. I’ve been using it for years, and in many different vehicles. Of all the vehicles I’ve used it in; none have ever needed engine work despite most hitting 200,000 miles before retirement.”
Reviewer John3620 said, “I’ve been using this oil in all of my vehicles, the oldest being a 2002 Chevy with over 200k miles. I have had no major engine work done and it runs as smooth as the day I purchased it. This is by far the best, but you know the saying, you get what you pay for.”
Sergei Olschewski offered, “Had a truck running in -45C with just over a quart of Amsoil 10W30. The truck still runs great – amazing lubricant for extreme temperatures. Will another brand do the same? Maybe. But at least I know that Amsoil works in -45C beautifully.”
Synthetic Motorcycle Oil Ratings
AMSOIL has also enthusiastically placed their 20W-50 and 10W-40 synthetic motorcycle oils in comparison testing with competing brands. Again ASTM testing methods were used to compare brands such as:
|Mobil 1||Royal Purple|
In the motorcycle synthetic oil comparison, the AMSOIL 20W-50 Synthetic Motorcycle Oils dominated the testing in categories such as:
- Wear control
- Shear stability
- Gear protection
- Foaming resistance
- Rust protection
Independent Synthetic Oil Comparison Test Results
Independent testing was conducted by Auburn University to determine whether AMSOIL Synthetic Oils Improved Fuel Economy under stop and go driving conditions in a diesel delivery truck.
- AMSOIL Premium 5W-40 Synthetic Diesel Oil was used in the engine
- AMSOIL SAE 50 Long-Life Synthetic Transmission Oil was used in the transmission
- AMSOIL 75W-90 Long Life Synthetic Gear Lube was used in the front and rear differentials
The baseline lubricants in the test were Chevron Delo conventional oils:
- Chevron Delo 400 LE SAE 15W-40 in the engine
- Chevron Delo Trans Fluid ESI in the transmission
- Chevron Delo Gear Lube ESI SAE 80W-90 in the front and rear differentials
In a scientifically controlled test using the SAE J1376 Fuel Economy Measurement Test for Buses and Trucks, the result was that switching only the engine oil to AMSOIL synthetic oil resulted in a 2.38% fuel economy gain.
Switching the engine, transmission fluid and gear lubes to the AMSOIL synthetic oils resulted in a 3.15% fuel mileage increase over the conventional Chevron Delo oils.
