I use this particular product in both my diesel powered Motor home, and my F350 truck. I used oil testing to determine oil change periods and have saved considerable money over fossil based oils. In addition easier starts, and increased mileage have added to the positive results of the AMSOIL use

Been using in 06 chevy 3500 has 253,000 uses a qt, in 25000 miles can't complain !

Run it in both of my duramax trucks one has 260 thousand miles other one Amsoil is all it's ever had both all clean as gold

I use Amsoil 10W30/SAE30 in my Massey Furguson compact diesel tractor. I've used this oil from day one. My tractor was delivered and I drained the oil that day and changed the filter. I do this with everything I own . Amsoil is the best..

ALL MY CARS AND RV USE AMSOIL OIL AND FILTERS AND HAVE NOT HAD ANY ISSUES USING THEM. ALL RUN COOLER AND SMOOTHER. THE ONLY OIL I WIL USE. ALSO USE ALL THERE OTHER PRODUCTS TOO.

I tried this oil the first time I ran it for 14,000 miles it test still good. The second time I ran it 19,000 miles, it still tested good. I may change the filter at 20,000 and go for 25,000 this time we will see how it goes. I think my Duramax likes it too!!!

I use this product in my diesel tractor and small gas engines.

Excellent oil!! Performs just like all Amsoil products do.

Run this oil in my 8000# open diesel truck. it has been ran in this truck from the time it was new.

I run the 15w-40 diesel/marine oil in my 99 Peterbilt. I've had excellent like with it for 3 years now and the extended drain intervals save me a lot of money per year.

I've used this oil in my diesel pick up since I bought it in 2005. It's had 11 oil changes in 11 years and 142000 miles and runs great. All the fluids in my vehicles are Amsoil products. Stick with the best.

I've been using Series 3000 5w-30 in my 2005 Ram 2500 with Cummins engine for 5 years now. I change it once a year, every 20,000 miles (without sampling...vlimd faith). Truck had 140k miles when I bought it and first put in Amsoil....it now has 240k and runs perfectly. I will always use Series 3000.

Great product. Run nothing but Amzoil in all vehicles including off road vehicles and boat

Have used this for years in my trucks .

Love this oil. Why don't you guys send stickers anymore?

I have 100k on my engine I service it at amsoils recommended intervals and have had no issues.

I have used this product in my 05 chev duramax for years. My truck has 155000 miles and I'm sure the oil has a lot to do with it

Our Kioti, non turbo charged, needs old school oil. But, in a 10-30 weight. Hard to find as most are 15-40. Our tractor works best with this oil.

16 plus years in gas and diesel engines, no regrets!!

Bought the 2012 Ram 3500 18 months ago. Didn't know what oil the previous owner used but took the truck home. Changed oil to amsoil 15-40 at 22000 miles. I currently have 90000 on the truck and performs great. I also pull a 39 ft 5th wheel
