Customer Ratings & Reviews

I have been using amsoil for Years and Years, I don't use any other oil. I use Amsoil for all my Vehicles, including my StreetBike, Lawnmower, 4 wheeler, Pressure Washers, Anything I have that needs oil, Amsoil Goes Into it... 100% Loyal Customer!!

Amsoil is the best. Hands down. I've been researching ways to prolong the lifespan of all my motors. Royal purple isn't even a close second. Do your own research. Amsoil is king. ..... anyways, I was needing quantity, viscosity and oil filter for 2019 dodge ram 1500 5.9l hemi. 7 quarts and a win filter for a little over a hundred bucks, not a bad deal. I change mine every 10k. Premium gas and amsoil and you should get 300k miles outta your engine. We'll see.

great oil I change my oil once a year

Great product with fast shipping

I have been using this oil for over 20 years. Every vehicle I have used it in has never had any problems and it has increased the gas mileage.

I use only Amsoil's best in my high output 2.0 Ford. It puts out 400 HP and turns high rpms. It pays to use only the best.

I put nothing but the best in all of my vehicles, and Amsoil is by far the best. Scott Galbreath an employee of yours, has always been great to me and getting what I order quickly.

I send a sample to Blackstone after 16k miles on an 219k miles Acura tsx. Didn't add a drop of oil in thay time They told me will hold another 10k. Impressive. I have the report in case anyone wants to see it.

Excellent high grade oil

I’ve gotta oil consumption issue so use this oil there 5-w20 works the best for my 12 Acura TL and i always highly recommend this oil to anyone and everyone..?

Every time I’ve ordered products from Amsoil it’s been handled perfectly. Everything arrived ship very nicely. No problems at all. Very easy to use the website.

Had this tested at 5k. Results were almost the same as when new. This is good stuff!

Bar none the best oil on the market!

I've used all the commercial "synthetic" oils in numerous vehicles at my place of employment, and in my own vehicles. Amsoil Signature series by far holds up better during oil change intervals, especially in small displacement turbocharged engines. Other commercial brands become very black and deteriorated over the course of a service interval.

Yeah I've been running this oil for many years and just used it on my jeep gladiator Rubicon.

Great stuff

I use Amsoil in all my vehicles! After I do an oil change with Amsoil, the engine runs quieter, happier, and healthier! Would recommend to anyone. There is even science behind it! It tests better than other manufacturers!

I've used Amsoil in all my vehicles and never once have had an issue. 200k and climbing on my current one.

Engines run smooth and quiet. Once a year oil changes are perfect with the Signature Series. Customer service is top notch and knowledgeable if you ever need to ask questions. Email responses are always quick. Been using Amsoil in all my vehicles, motorcycles and small engines for 20 years. Noticeable difference and improvement.

Excellent advanced oils I’ve been using for years with no issues and full motor protection in muscle car performance.
