Never had a problem with amsoil

For the quality, the price, and the ease of shopping, this is what I buy! I buy mostly because of quality, but the rest just makes it even better

I have been using Amsoil for many years. I drive a 1997 Jeep Cherokee with close to 160k miles. The engine has had Amsoil for years. I use 10w30 and it runs fine. It uses a quart in 5k miles and that's when I change it. Great stuff.

Great product at an extremely competative price!

Have been using the oil for a long time and very happy with it

Best oil for race engines Farm equipment or just your around town vehicles I use it in everything I own

I have been using this oil in all my cars for many years..

Oe amsoil oil is the best I've use every 4,000 miles good stuff

Provides my 2005 & 2014 Fords great protection.

This is the only oil in my vehicles since day one, drove home from dealer , changed oil to amsoil.

Great products. Fast shipping.

Put Amsoil after 1 oil change in new vehicle..Runs great 5.7L Hemi in Dodge Durango runs hard in Pony..50k in 1yr -30° in Canada to 101° F on Route66. Vechicle got great fuel economy.. Great oil...????????

Overall this is a great product for a lower price. However the difference in price is worth going up to the XL oil, twice the oil life for only a dollar or so more.

I have 3 Fords and they all use Amsoil products. The daily drivers use the OE product and my beloved 1996 modified Mustang runs exclusively on Amsoil's Signature series. Very satisfied.

I had always purchased the top-line signature-series for my cars and trucks in order to take advantage of their long drain intervals. Recently I bought a new midsize truck with a V6 engine. The dealer offers a free one-million-mile powertrain warranty to the first owner. Owner must follow the factory-recommended service intervals; oil drain and filter come every 5,000 miles. I went with OE because it has to be drained so often, but would it provide about the same protection and mileage as the SS? Before OE the mileage average was 23.4 mpg. After 5,000 miles on OE the mileage average is 24.3, an increase of about 9%. The engine is very quiet at idle and runs very strong. No oil seeping anywhere.

Owning an air-cooled Harley and a Subaru with leaking head gaskets, I can't really afford to take chances with oil. AMSOil is competitively priced and in some cases, less expensive (see Motorcraft gear oil vs AMSOil)

Using it in an engine that burns oil. It is more affordable that the signature oil but still quiets down valvetrain and runs smooth.

I use this oil in the winter time since i put around 6000km a month regardless. I like to change my oil a little more frequently in the winter season since i idle more with heater on and since fuel can get diluted into the oil since it takes much longer to warm a vehicle up in the winter. I use this during the winter and go 2 month intervals/approx 10k-12k km. Summer time i jump upto Signature series 5w20 alongside the EaO filter and go 4 month interval/20-25k km. This is a '12 mustang 3.7L cyclone engine with just over 215,000km. Still looks like new down the oil filler! I'd say the OE & XL are far better than whats on the shelf at any store.

Read the reviews and test comparison 's of Amsoil versus other brands of synthetic oil. It appears the Amsoil brand out performed the others in most instances and that is what sold me on their product.

Bought a ton of 5W20 and put it in my 09 Cherokee Laredo. Smooth driving all the way!
