Shell Rotella T6 Full Synthetic 5W-40 Diesel Engine Oil, 1 Gallon (3 Pack)

Use this in my 2004 Sprinter. However I mix it with the shell non-synthetic equivalent so it doesn't blow past the rings so bad. My 2004 has 280,000 miles on it. Still works excellent but synthetic is a bit too thin. I must add about 2quarts to it between oil changes. All regular oil drops mpg by about 1.5 mpg. Mix the two to about 3/5ths synthetic to 2/5ths non-synthetic and I get the same mpg as all synthetic and I can go the distance between oil changes without adding any oil. Good compromise and less work, slightly lower cost. I also use Diesel Clean in the fuel to boost cetane, stabilize the fuel, and make the fuel pumps last longer (and improve mpg). I get about 25 to 26 mpg when I add Diesel Clean and use synthetic oil.

Very Good oil decent price.

Best oil for my Duramax at a great price dropped off at my door with subscribe and save. Couldn't ask for more.

Excellent oil.

I’ve had great results with Shell Rotella T6 5W-40 in my diesel engines. It flows well on cold starts and maintains strong oil pressure once the engine is up to temperature. The full synthetic formula is worth the extra cost for the added protection and consistent performance. I’ve used this oil for years and haven’t had any issues. It’s a product I trust and will continue to buy for all my diesel equipment.

Great oil! Using it on my 6.7 Cummins RAM 3500

Used this for my 3.0 EcoDiesel and everything went smoothly. Good quality oil and the engine runs great.
