Customer Ratings & Reviews

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.

Run this in my 2016 Subaru legacy 2.5 and works well

Seems like a great product gas mileage improved about 1-2 miles per gallon hiway engine sounds slightly quieter

Amazing oil

Running smoother and cooler, hardly any burn off and keeps the inside nice and clean.

I been using this in a 2016 Chevy Trax from new! uses on oil @ 53'600 miles!

Great product! I use it in my 2018 f-150 with the 2.7L ecoboost now granted a 1.5 mpg increase isn't much but it ads up when you put on a lot of miles every little bit helps. It's even nicer to have the peace of mind with the added wear protection due to the new start-stop technology who know what long term internal damage its helping to prevent due to these added emissions systems. Big thanks to Amsoil for the great products keep up the good work!!!

I feel the AMSOIL 5/30 is the best protection for my engine.

Awesome oil,

Good oil I won't use anything else in my 2018 Camaro ZL1!

my truck is getting the best gpm it ever did
