Customer Ratings & Reviews

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.

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

Been using since pretty much day one!

I've been using this oil for a while, but the price has increased $26.30 between my January and June orders. At this point, I'm not convinced the extra cost is worth $200 + oil changes twice year. This will probably be my last order, and I'll likely go back to buying Ford oil instead. The product has worked well, but the recent price increase has made it difficult to justify continuing to purchase it.

Great oil! The bottles make it easy to pour.

sticking to what works and what has been used in the truck before me

I have been using this exclusively in my 2016 F350. It out performs the Motorcraft Oil by a large margin. I drive lots of short trips. The Florida temps in Spring, Summer and Fall are routinely above 90°F. The severe service schedule suits me for my driving style.
