Customer Ratings & Reviews

I switched over from 5w20 to 0w30 because I use my 13 Ram 5.7 Hemi engine for towing ,this engine runs great, went on vacation this April to Tennessee, didn't Tow any thing my average millage is now (Hwy)19.2,this is Great the engine just feels good,been using Amsoil since 1988.

I use signature 5W 30 in my 2007 Range Rover Sport Super Charged. I will not use any other brand, the truck has had regular oil in it from factory to the 5000 mile mark, since then we have only used Amsoil signature synthetic and rightfully so the Range Rover has 245k miles and it' still as strong as the first week we owned it. Thank you Mr Amsoil.

Right for the Tundra!

Great product

I use this in my new car.

Product used in a 2016 Mustang GT with Roush supercharger. 690 HP which is up from 670 on factory oil. If you cant feel the difference using AMsoil, dont ride a bicycle, motorcycle, or fly an airplane!

I uesd amsoil in my mother car. Did a engine flush. With her oil change. When it was done. She drove to her house which is up a mountain. She notice right away how smooth the engine running. Big difference she said. Thats from a women who dosent know about different oils.

My Toyota RAV4 runs smoother with better fuel economy that it did with the MOBIL Full Synthetic that was being used previously. This oil is also used in my Cummins whole house generator. Engine runs smooth and quieter.

I know that Amsoil is relentless in producing the finest motor oil anyone can purchase for vertually any vehicle. My high performance car still runs like new with no issues using Amsoil SSO 5W-20 for the last ten years.

Every six months oil change intervals at 10,000 miles with Amsoil's oil filter. UOA came back showing the oil had plenty of life left in it. 10,000 and every six months is where I feel comfortable.

Best product, fast shipping.

I use it a2005 Mercury, it was what he used so I just kept using it, it has around 220500 miles on it and I think the rear seal has a little leak. I also us Am soil in my Harley and has made a difference . I have also bought it for my 93 diesel I am working on.

I have the highest of faith that ALL Amsoil products are the absolute best that money can buy

Love the long life of the oil. Still retains lubrication quality after a year in use.

AMSOIL customer for 20 years. Outstanding products. Best engine oil products available.
