Customer Ratings & Reviews

The oil is second to none. A bit disappointed that you keep running out of my oil filters. If I'm using Amzoil which I have for many years then I also want the best filter for it.

Have always used this oil in my 2006 Tundra V8. After 20 years does not use any oil and runs like new.

Have used this oil on two vehicles requiring this weight. Highly recommend as it seems to keep our engines in top condition. I do change it every 5k miles as daily commutes require a lot of stop and go.

Great product. Excellent service in getting my order.

Probably the best motor oil available. This synthetic just sounds different and feels smoother than any other brand I've tried, and I think it delivers slightly better MPG than other synthetics. I have no reservations at all taking this oil to it's annual service interval, which for me is roughly 10-12,000 miles. 2004 Toyota Sequoia - 236,000 miles

Protect your engine with the Best. I change Signature series every 5,000 miles. I cannot afford to buy a new vehicle.

I have used Amsoil in my cars and motorcycle.

Have a newer car that uses 0w oils. Oil had been changed twice by dealer with whatever was cheapest that week I’m sure. Did oil change with amsoil and wow. The entire engine sounds drastically quieter. Plan on changing every 3000k to keep turbos and small passages clear. Thank you amsoil.

I just bought a new car with a few miles. I drove it around for a week. I'm not sure what the manufacturer puts in so I switched the new oil to Amsoil. What a significant change. The car runs smoother with Amsoil. It feels like a totally different car. You get really good results when you use the best oil.

Keeping my old cars running like new. My car run so much smoother with Amsoil. There's nothing like it.

It protects my Honda Civic SI 1.5 liter turbo in the summer heat. Winter time I run the 0W-20 .

Want the Best Buy amsoil

I have 180k on the odometer, and the engine is smooth, quite and has ample power. Amzoil is changed before 5k.

I can always trust Amsoil

I haven't changed my oil yet , I am waiting to get the 5 W 30 instead of the 0 W 30 because my truck will sits 2 or 3 days and not be started so I want the heavy r viscosity for better protection .

Use amsoil in everything.

Awesome oil. I don’t go the full 25k miles but I did extend the change intervals to every 8k miles. For my car to be a 2004 with 230k miles the engine still runs quiet and smooth using this oil.

I have used Amsoil 0W-30 in my truck for over 10 years. I love this product, I have not found in other oil that works like Amsoil.

The signature oil was recommended to me and I’m glad I tried it. This oil kept my engine cool during a blistering hot cross country drive recently. I was confident the engine was fully protected. Thanks for making a great product!

I would say best oil I’ve bought in a long time would recommend to everyone
