Customer Ratings & Reviews

great transaction , great product

Oil change every 5k, it’s served me well.

10/10. I have been running this oil in my truck since new. Pushing 300k km and it still doesn’t burn a drop of oil in between services.

Keep my business running without a worry

I never worry about oiling issues with my John Deere 2320. I've put an increasing number of hours on the tractor in recent years which I use for a combination of very hot weather/ conditions pasture mowing, chipping, snow removal and logging. My usage ranges from low speed operation in colder weather to high rpm PTO usage for chipping and pasture mowing. Logging requires a fair amount of idling then low rpm winching and mid rpm heavy pulls and pallet fork usage for stacking logs. I change my oil once a year (50-150 hours depending on the year) I don't abuse the tractor but it's working hard every time that it's running. I worry about breaking parts on it but I never worry about engine lubrication.

Great product fast shipping

Run 35k changes on the cummins running this a amsoil ea080 and the amsoil large bypass system. Last truck got 1.3 million miles on all original cummins 6.7 engine .

I am so pleased with this oil for my truck.

I have used this oil for the last 10 years in a 2015 duramax. I work the truck every day and have 209k miles on the truck. The truck doesn’t use any oil between its 7500 mile oil changes and still runs like new. I recommend giving it a try.

I used Amsoil in the 1980’s back then you had to know someone that sold it. Now we can order it online, it’s costly but I use it until I reach 12000-15000 miles which is usually about a year and a half. I trust the brand. I keep a spare case on hand.

Good clean product.

Great oil , no complaints , it even got rid of the classic duramax type writer tick ! I'll never use another oil in it now that I've used this

Always a pleasure Pays to be a member for discounts My goto products

My 3500 Ram HO definitely prefers the 5W-40 over the 10W-30. It runs noticeably smoother and quieter with 5W-40.

My 7.3 diesel loves this stuff!

Been a long time Preferred Member. This is my first diesel vehicle. I have trusted this oil in my gas engines for 25K change intervals. I will trust this oil in my diesel.

Only the best for my G3 RAM. Original turbo, no oil issues. 125k miles. What is not to like?

Ive been using amsoil almost 30 years and has certainly proven to me that it is everything they say it is..I certainly recomend it. Ive just started ordering directly through amsoil for the 25% discounted price and one of my orders had 2 quarts damaged, took a pic and emailed it and within hours they responded and sent new ones immediately. Couldnt be happier with service! ⭐️⭐️⭐️⭐️⭐️💯

The best

I have continually used the signature series 15w-40 from the first oil change when the truck was new. My 2014 Ram 3500 still runs strong. I always have my oil analyzed at every change. After 229k miles that analysis is still in the green. Had a couple minor oil leaks and a bad turbo actuator and that is all I have had to repair. Thanks Amsoil for your superior products.
