Customer Ratings & Reviews

I like knowing that I have superior lubrication with AMSOIL, especially when cold starting in the extreme cold temperatures.

Just bought a new car with 90k miles. The Carfax is missing info from 70-90k miles, so I want to make sure I take care of my engine as well as I can in case it was neglected for those 20k miles. I trust Amsoil to extend the life of my engine as long as possible and it feels good to have the good stuff.

Best stuff on the market

No matter what type of engine you have Amsoil is the only choice you should make, from small two cycle motors to big block 2500 or anything in between. It is absolutely the best wear protection product, regardless of how much it costs, it’s way cheaper than replacing unnecessarily worn parts..!! Just use it..!! 🇺🇸

exceptional resistance to thermal breakdown.

Awesome oil. I have been running this in my 2011 F150 Raptor 3 years and 50000 miles now with no issues.

Product is great and reasonable prices and fast shipping ! I use in all my vehicles

I have put this in all my vehicles even my boat. Its by far the best oil. I also have alot of friends and family turned into amsoil as well. So thank you amsoil for making great oil and filters

Received my shipment fast. My Ford F250 6.2L runs better and smoother than it did with other Synthetic oils. I highly recommend this oil for anyone who wants their automobile engine to last longer.

I have used this product and many others from AMSOIL and it's performance has been second to none. Yes i have seen increased fuel mileage, and I know this means less friction, easier cold starts and better hot weather performance. Yes you really can realize a difference of you switch from your current oil and Use Signature Series Synthetics

Have used this product for years and hundreds of thousands of miles. Send drained oil for analysis occasionally and after as much as 17k miles they report oil is still usable. No, I don’t pour it back in at that point but good peace of mind to change oil only once a year regardless of mileage.

I have been using Amsoil 0W-20 in my Subaru Legacy since my first oil change. The car has 131+ and runs like new. Very happy with Amsoil products.

The second time using this oil I put it in my Toyota Corolla and works great lasts a lot longer than expected

This the only oil I use in all of our cars

Great product

Using this during the winter in my WRX, switching to the AMSOil 5w-30 in the summer. No worries using this 0w-20 as it's better than every other companies.

This is about as good as it gets for longevity and mileage. 25K intervals for changing oil is unprecedented and will be experimenting on my truck.

So far I've noticed better mpg in both vehicles will send off to test oil sample I. Fee months and will compare my results with royal purple results but I am sure this is the superior oil of the 2.

I love these products. Normally, I would use the AMSOIL XL, but I switched to this a couple of weeks ago and noticed the engine ran quieter and smoother. Thank you!

Good
