Shell Rotella T6 Full Synthetic 15W-40 Diesel Engine Oil, 1 Gallon

Good oil for a reasonable price.

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.

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.
