Great oil unbelieveable mileage no problems whatsoever

I am using this oil lately and I am very satisfied with it. Usually I change it every year but I didn't exceed 9500 miles. Engine is running smooth and quiet. Thanks.

Good product

I use Amsoil in my 4 vehicles and ZTR mower. It's the best.

Amsoil is the only oil that has consistently been able to withstand the unbelievable abuse I put my engine through.

my Subaru forester says thank you and purring along for nine years could not be a happier person.

I have been using Amsoil products for over 20 years. Every vehicle I own has been run with Amsoil. The product is the best on the market and I won't use anything else. I have a Tacoma with over 300,000 miles on it and it still runs like new and a Mazda B-2600 with over 400,000 miles on it. I use the transmission fluid, gear oil, motor oil and filters. I am a customer for life.

So far so good! Been about a month, its August and hot here in KS. Definitely starts up and almost "breathes" and revs easier. It will be interesting how it feels starting come this winter. Im replacing my antifreeze and adding the additive this winter too. Excited about that!

Excellent product.!!!! Outstanding service!!! You couldn't have done any better.!!!!

Been using AMSOIL since 1985 in everything from snow blowers, lawn mowers, cars, trucks, ATV's Motorcycle's & Stock cars never had a oil failure

Best oil I have use on my chevy truck

Best oil out there!! Great engine protection!!

I buy this oil all the time! Every oil change! I have used all the brands over many years and Amsoil is my preferred!! I have put 150k miles on my Tundra using this oil and it's runs like new!

I run this in my ecoboost explorer. Makes motor sound smooth and quite

The best oil I have used by far

Almost 200,00 miles on a 5 cylinder motor and it still runs great, started running amsoil at 2000 miles

I use your products because I trust them.

Best synthetic oil on the planet.

I use this in our 2000 4Runner, which we use to pull our camper during the summer. It gets a real workout in the Colorado mountains, and the signature series has been great at protecting the V6 engine from high stress and heat.

It is what the car manufacture calls for, and we have had no problems with just changing the oil once a year. We now have over 50,000 miles on the SUV, and it averages better fuel economy than what the EPA rates it at.
