  • My Go To Diesel Oil
Size: 1 Gallon Style: 3-Pack Configuration: 5W-40
I've put lots of miles on three different diesel trucks using Shella Rotella T-6 and I've never had an oil related issue. I have sent this oil to Blackstone laboratories in the past and it always comes back within specs all the way up to the 15k mile mark. The price is decent. If isn't broke, I'm not going to change. ... show more

  • The Only Oil My Duramax Trusts — Full Synthetic Powerhouse
Size: 1 Gallon Style: 3-Pack Configuration: 15W-40
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. ... show more

  • Rotella T6 is for me, the ultimate multi viscosity synthetic oil .
Size: 1 Gallon Style: 3-Pack Configuration: 5W-40
I use Rotella T6 in all my engines, both gas and diesel as well as my farm tractors. For me, T6 is the ultimate lubrication. Having said that. this pail is white, not the usual blue and it leaked just a tad in transit. Not a deal breaker as the per pail price is excellent and I will purchase it again, just like I have in the past. Rotella in the 5-40 viscosity insures easy cold weather starts and performs excellent in hot weather as well. ... show more

  • Protect your investment, worth the cost.
Size: 1 Gallon Style: 1-Pack Configuration: 15W-40
My diesel is getting old, no problems just wanted that little extra protection for summer months, always used the oil for 1999 F250 7.3 Diesel. Run around 6000 miles between my oil changes, I use a bigger oil filter than OEM Ford. I do put actives when changing. No problems with order. This truck was my work truck, and now my retired truck. 210K on it now and towed a car from Cal to TN with no problems, with the protection this oil provides. ... show more
