I finally pulled the trigger and switched to Amsoil. I've been using 15-40 in both my diesel pickups and I'll have a more in depth review once I change my oil again.

Great oil for my 2004 Cummins with 200,000 miles keeps the engine running smooth

Instantly sounding much smoother considering how industrial this engine is as a whole- Much quicker to build oil pressure than the Rotella with 5k on it with an ambient of 7*F- Being in So Cal and having a interesting time finding 5w40 approved engine oil,glad to know you guys have it on the shelf- Have purchased a few 2.5 gallon jugs since-

I have a 25 hp LS tractor that I have used the max duty oil in since new and it’s been great. The tractor seems to run cooler than the factory oil and it gets hot in Kansas during mowing season

For me to be the first time using Amsoil And rate the product I’ll have to see how looks when I do the oil change again then I can said all good or bad things since I never heard of Amsoil before but l am impressive with some of the challenges they had put against other competitors I hope that Amsoil would be my first and forever oil For all my cars

Great oil, let’s my duramax run cooler than rotela oil and stays clean upto 5,000 miles!

Watch out these ram dealers are using 15-40 conventional all year long in the diesel cummings ,motor heats up faster but extremely bad for motor as it doesn't flow . I switched to amsoil immediately much quieter on startup and warmup nice steady oil pressure the whole time

Started using this on my 07 Duramax and now use it on my 19 Duramax. Just wish I could get a EA filter.

Merci très bon service

I’ve done my research on this oil before making a purchase had contacted the number of vendors and watch multiple videos on YouTube regarding testing. I had bought a new turbo for my truck and it was recommended to use Amsoil two pre-lubricate my turbo. Outstanding customer service and the delivery time was top notch

always checks good with oil analysis even up tp 20,000 miles

The have the oil for my vehicle but are always out of filters

Great oils for excess mileage

Have two company truck that had a ticking sound. After switching to amsoil , the ticking has gone away. Great oil for all trucks in general. Highly recommended

I use Amsoil products and everything I own and why anyone would be skeptical about Amsoil products is beyond me.

Great oil and great service

Amsoil is the only brand in the game you can trust. As long as they keep their formulas and quality the same ill be a customer for life.

The oil is perfectly match for you Diesel engine. Plus the containers are just the right size.

Quality Product! Excellent delivery, ordered on a Friday and was sitting on my door step Saturday. Just switched from Rotella T6 due to shortage but I believe I’m going to be running amsoil from now on!
