Customer Ratings & Reviews

I use the 15W40 in my older diesel truck and I use the 5W-40 in newer diesel trucks and my entire gasoline fleet it's fantastic because I can run 15K between changes and the oil that I am draining usually looks so exceptionally better than anything else on the market looks like after 5,000 miles

I have a 21' Ram 2500 Mega Cab W/6.7 Ltr motor. I've used this oil since it's first oil change. 10,000 mile oil changes are recommended and I usually follow that recommendation consistently. This last change, I've monitored the trucks 'oil life' percentage gauge as I'm in the middle of a move and the truck is towing a 24'x8.5' enclosed trailer full of household stuff. I reached the 10k recommended limit and still had over 30% oil life remaining. I chanced the extended oil life and am now at 20% and 2000 miles past the 10k change interval. I'll change the oil before my next long journey. I wouldn't have trusted any other oil to run me past the recommended limit, but Amsoil has always met and exceeded my expectations. I'm an Amsoil customer for life.

I can tell how the turbo works more freely with Amzoils diesel oil

This is peace of mind in a jug. I use this every oil change in my 2016 F350. Based on all my research and lab results, from several sources whom have tested this product against other brands. I know it's a little bit more than using some of the other available brands. However you get the added peace of mind knowing you're using the best product available for your truck. It's worth the added expense for me because I plan on keeping this truck until the wheels fall off.....

Love Amsoil products. The recent price increase of 20% is excessive in my opinion.

AMSOIL produces superior Diesel oil products. I have used AMSOIL products for both gas and diesel Ford trucks for over 25 years. My 2011 F250, with 74,000 original miles, has all of its fluids changed with AMSOIL Diesel, Transmission, and Antifreeze products since the first 5,000 miles on the vehicle. My diesel mechanics swear this vehicle runs as well as it did when it was new at the dealership.

quality

My truck love this oil.

Great oil for my 05 Silverad with 278k miles, looking to the most out of her as best i can, that is why I use Amsoil products.

Best oil on the market for my 6.7 ford

It bit more money. I BEEN use 10 30 in 6.7 ram foe year now with amsoil by only stay cleaner longer

I have an issue that every time for the last six months your company is constantly out of stock of the oil filters but if you call a place the order over the phone for will call at a location then the oil filter is suddenly available... I find this frustrating. And poor service that it has been 6 six months and still no oil filter in stock to purchase online?\

Such a firm believer in this product. I have seen first hand how this product protects the life of an engine. There is no doubt that Amsoil is the reason my vehicles can all become "high mileage" transportation and still be running smoothly when it is time to sell/trade!

Good stuff so far

Watching a lot of videos, and AMSOIL cannot be beat. If feel at ease using AMSOIL. I also installed the BMK28 on my 6.7 power stroke.

Loving this oil so far! Been running it in my truck the last 1500 miles and I love the confidence that comes with using the best oil on the market

I’ve been using Amsoil for nearly 20 years, simply had no rival

Simply the best

Will always use in my diesel trucks

Only oil I will put on my Ram 2500
