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!!

Best oil on the planet. I run AMSOIL fluids and filters in all my vehicles. 👍👍

Great customer service, quick shipping and a quality product

Very good product quality.

⭐⭐⭐⭐⭐ 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.

Just the right amount of oil I need for the vehicle

Best product to protect your investment In the long haul HANDS DOWN!

Great product and great Customer service

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.

I run 5w30 signature series in my 2021 F-150 3.5 Eco Boost engine. This engine has twin turbos and they run extremely hot. I feel Amsoil gives the protection needed to reduce engine and turbo wear. Phil

I have been using Amsoil in my Subarus for over a 15 yrs. I usually run 18-20k filter every 5k before changing. I have never had any issues ever. Best there is

The large oil jug is a convenient size and bit more economical. I will only use Amsoil in my high meager Tundra
