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.

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 .
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.
Bottom Line
Yes, I would recommend this to a friend.

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
Bottom Line
Yes, I would recommend this to a friend.

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!!

⭐⭐⭐⭐⭐ Excellent products! The AMSOIL engine oil keeps my engine running smooth and quiet, and the oil filter is high quality and provides great protection. I’ve had a great experience with both and highly recommend them.
Ordered and picked up the same day - could have had it delivered but i was in a hurry. I use it in all my
cars and trucks for the last 15 years and I never have to worry about my engines.
Bottom Line
Yes, I would recommend this to a friend.

I’ve been running Amsoil in my motorcycle and cars for years. I trust their products. This signature series seems like the ultimate oil. Highly recommended.
