Customer Ratings & Reviews

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.

What an excellent product! I always want to use the best products for my vehicles and with AMSOIL that is exactly what I got.

The best motor oil, money can buy,I ran it a full 15 months before changing it. And it was still clean.!!

AMSOIL is one of the best oils on the market. I am typically 3,000 to 5,000 mile oil changer. I do a lot of stop n go traffic. If I go a little longer between oil changes, nothing to worry about it. The longevity of the oil is there. My gas mileage seems to be a little better with AMSOIL due to the lubricity. Folks use this oil and stick with it. Your engine will last much longer.

Since I started these oil, when my uncle recommended to me. So far its one of the best oil by far and I don't have problem with it even though run my car over 5k since my last oil change. For me, I will recommend this oil to my friends and family.

Great oil

Best oil ever it is the best oil you can use in any motor. One se with over 250k miles
