Customer Ratings & Reviews

AMSOULS NEED RETAIL OUTLETS TO ADVERTISING.

I highly recommend this product. I only use amsoil products in everything from my compressor to my vehicles. They have done there homework to produce great products.

Oil pressure is improved with this product

Trusted product! This particular oil was made for my engine what can you ask more? They took the time and knowledge to make the oil possible for my car... its really a no brainer! Nice to have a compagnie that's back you up!

While I can't say the car runs better with this vs another top synthetic, I have hundreds of thousands of miles on my vehicles with this oil only changing once a year. Great stuff!

I have been using AMS Oil for 18 years and wouldn't use anything else. It is by far the best and all of my vehicles with several hundred thousand miles on them combined is the proof.

I doubled my miles between oil changes which saved me money, I use it in my small truck also.

So I run Amsoil signature series in all my vehicles. I run 5w-20 in the 2015 Jeep Rubicon Hard Rock and when I changed the oil at 7000 miles of use the oil lab came back and said to change at 9000 next time and see how it's doing. The wife's 2011 Subaru Impresa 5w-30 oil was changed at around 7000 miles as well and the results were the same! I think once the oil is tested at 9000 they will most likely advise I go even longer. They measured for contaminants as well as assessing the TBN which both came back outstanding, and both engines have zero issues. Black Labs is where I send my oil. The higher price for Amsoil is worth it in my opinion especially when I can go so long in between changes. It pays for itself.

I have numerous vehicles with 60-400,000 miles on them that have been running Amsoil most of their lives. All still have original engines. What more can I say?

Best you can buy for your vehicle.

The best price and solid transactions

So far so good. Only have 26k on the car so far.

Have been using this oil since around 2006. My 2006 Ford E350 work van has145,000 at 15,000 mile change intervals before I sold it . My 2006 E350 15 passenger van currently has 185,000 at 20,000 mile change intervals. Great oil have had no issues with it.

Engine has been running smoothly after changing into this signature oils.

I was nervous switching from high mileage to a full synthetic, but 84 Chevy pickup now runs better than ever and actually has less leaks now. I also run this same oil in my 84 Honda Nighthawk motorcycle.

I have used this product for years, I wouldn't trust any other product in my vechicles.

All I use in my vehicle's is Amsoil ...I wanted to put good oil in my vehicle's so tryed Amsoil and been using it for 20 years now. It's the best hands down period...

Solid oil that's maintained it color and viscosity for 3k+ miles of spirited day to day driving

Big deal. I've used Amsoil for about 10 years now. I've had really good results, but then I did using Shell Totilla for diesels also. I'll keep using this product until I get my Model 3 Tesla.

I have been using this product on my 2010 Mazda 3GT since new. I am nearing 186,000 miles on the car and have the oil checked at every change. The analyzers are always telling me the oil has more life left and everything looks great. I will be using this product in every vehicle I own and recommend it to everyone who asks. A first rate product!
