Been using Amsoil’s 15w-40 on my Duramax for years and I absolutely love it. I can get 15-18k intervals out of it and it’s still got a couple thousand more miles left in it. Take care of your vehicle and it’ll take care of you… run amsoil

Great product with super fast shipping! If you have a tech question they are quick to respond to your email.

Have used Amsoil Diesel Oil in My 2005 F250 for 190,000 miles i would not use any thing else.

This is the first time I have used the signature series oil I always used the silver jug previously. I rate this oil so highly due to the instant noticeable increase in fuel economy after my most recent oil change. The big diesel runs at lower RPMs during all driving ranges and I have gained approximately 2mpg!

Love it

I've been using Amsoil in my 6.0 Powerstroke for almost two decades now highest quality oils available that's why I use it and that's why I recommend it

Great product have been using it for several years

Best oil I have ever had!

I have been using this oil in my long distance trucks for years. Cummins and Caterpillars Oil performance is what i hold in high regard and this has never disappointed me.

Only use amsoil I. My cars and truck. Won’t allow anything else in my motors

Awesome oil for my lb7 Duramax it has 306,221 miles on it and still running like new, iv never had any issues with Amsoil, I highly recommend it for any Duramax

I've been using Amsoil Signature 5W-40 Diesel Oil in my 2015 Ram 1500 EcoDiesel since it was almost new. I'm confident that using this oil has helped keep my rig going strong without issue for the 240,000km's that are on it so far.

Excellent service and delivery

After 25,000 miles oil was dirty but not sooty. It did not thicken up the viscosity of the oil.

All I using my Duramax

Amsoil is the best. I really feel that this oil has my back when I put my foot to the floor. The delivery service is excellent.

Learned about Amsoil by watching Greg A. On YouTube. Tried it in my 12 Ram 2500 (Cummins) and used it on both my 21’ 3500, and now my current 14’ 2500. Soon I will be ordering it for my 01’ 2500 (Cummins) I definitely noticed a difference in engine chatter(noise) after doing an oil change with Amsoil. Ram quieter and smoother. I won’t run any other oil. Thank your for the great product!

Amazing for my 2015 ram 1500 ecodiesel

Best product in the market, use it on all my motorized equipment, from my vehicle to chainsaw

This oil was sent to two friends in Zambia, Africa to use in their Toyota Hilux pickups. It will not get there until July 2023. They have used it before and really like it.
