Brandon S. –
I’ve been using Shell Rotella T6 Full Synthetic 15W-40 exclusively in my Duramax diesel truck, and I couldn’t be happier with the performance. This oil is built tough, just like my engine needs.
Here’s why I stick with Rotella T6:
Full Synthetic 15W-40: Perfect viscosity that protects my engine from cold starts and high-heat operation.
API CK-4 and CJ-4 Approved: Meets the latest diesel engine protection standards for reduced wear, deposits, and oil consumption.
Enhanced Shear Stability: Keeps the oil film strong under heavy loads and high temperatures.
Advanced Additive Technology: Helps fight soot, sludge, and corrosion—critical for a diesel engine’s longevity.
Excellent Wear Protection: My Duramax runs smooth and quiet, even towing heavy loads.
Using Rotella T6 gives me peace of mind that my truck’s engine stays clean and protected mile after mile. If you drive a diesel and want dependable, top-tier synthetic oil, this is the one.

Wish i could buy it in a 55 gal drum. I have been running this in my 11′ Ram 2500 for years no issues with oil pressure or wear. It definitely does the job.
Amazon Customer –
Good oil for a reasonable price.
Glen Maxwell –
Good product
Robert Moen –
Great oil,great price
D. Williams –
In my opinion, Shell Rotella 5w-40 is the best oil performance and price wise for any heavy duty diesel truck. I use this in both my 2004 Ram 3500 with a 5.9 Cummins and in my 2015 F250 with the 6.7 Powerstroke. This oil and a good filter keeps my engines running like a champ. I live in West Texas where summers get ridiculously hot but it can get cold in the winter. The 5w-40 works great in both conditions and I’ve never had issues with cold starting either of my trucks unplugged.
