Protects my engine and my sanity

This has always been the go to for our cars.

I’ve been using Amsoil for nearly 20 years, simply had no rival

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.

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.

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.

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 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

If any of my gasoline vehicles require synthetic oil 5w-30 signature series is what it gets no matter what the manufacturer says. It’s never let me down and it won’t! Great oil!!
