I've been using this in my '06 Dodge diesel for years at extended change intervals. I also use it in a small diesel tractor. It gives me easier cold weather starts than 15-40. I don't see any reason not to continue to do so. I run Amsoil in two generators, two motorcycles (Harley Davidson 20-50 and KTM 15-50) and run the Saber oil in my trimmers. No complaints.

Been running this oil in my 7.3 powerstroke for 200k and truck has 300k on it now. I usually ran the oil for about a total of 10k miles with 1 filter change at 5k miles, but recently I decided to have my oil tested and with changing just my oil filters every 5-6 miles. I ran the same oil for over 18k miles and it still checked out good. I do hotshot so I put on miles fast and I won't use any other oil brands.

Happy with your products. Ships quickly. Easy to use website.

Used Amsoil in my 2006 Ford Van. runs much smoother and much quieter now than previous oil that has been used. Seems to have more pick -up that before!!

Absolutely appreciate this oil product for my 7.3 diesel and the truck loves it too will continue to purchase.

Absolutely love this in my Duramax runs better gets good fuel mileage

Great product use amsoil in all my vehicles and snowmobiles should say all my toys

My truck use to go throw 2 qts of oil running rotela 5w40 in 5000 miles. Switched to ams oil and now I can go 10000 miles no oil lost. I am very happy.

Great product! Will continue using!

Gives me all the protection I need in my Duramax. Gives me better fuel mileage then Rotella

Amsoil is the best and cost effective oil I have ever experienced especially driving on average 4000 miles a week.

Great Synthetic Diesel Oil. Amsol is one of the BEST in the Industry. Trusted and time tested products.

Love Amsoil products! Fast shipping as well.

Amsoil is the real deal nothing works better in my 07 6.0L PSD. You really notice the difference on the cold starts. It runs so smooth you compared to any other oil I have used.

Great oil!

This oil is very good, IMO, for cold weather climates. Helped on cold day starts and the engine runs much smoother and quieter than before.

Excellent oil for heavy towing, with a good Donaldson filter I’m going 10,000 plus miles between changes on my Cummins 12valve, also like the added protection for the Turbo which gets HOT towing long grades with my 5th wheel

Been using 15w40 in my 07 duramax for over 150k without any issues. Sometimes it maybe 10-12k between oil changes… no issues. Ordered a 2.5 gal jug… got damaged during shipping. Amsoil sent another one out (so I thought) got the box… 2x 2.5gal jugs for free! Great customer service! ⭐️⭐️⭐️⭐️⭐️

Months of research has brought me to using this oil in my 2007 Silverado classic 6.6 with an Allison trans. There is nothing better! While pulling 42ft fifth wheel if the temperature outside is hot 95’ and the incline is long enough for the truck to start heating up 240’ my sensors detect that the oil is low and the truck will go into limp mode until I shut down long enough for the sensors to reset. The truck checks out fine, master mechanics have come to this conclusion.

Wonderful product, I run amsoil in everything. Definitely worth the money. My opinion is this is the best quality money can buy. I ordered Monday night, had product by Wednesday evening. Amazing customer service!
