The Only Oil My Duramax Trusts — Full Synthetic Powerhouse

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.

Protect your investment, worth the cost.

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.

Was Recommended for MEP-803A Army Generator, Seems to Run Well on this Oil

Bought this oil because it was recommended for my MEP-803A army generator. Seems to work well and I think is lower friction than the original oil, because I noticed I needed to turn down the RPMs slightly to get back to 60Hz. Possible improvement in fuel economy.

Great Oil, Even better Warranty

I hesitated to switch from MotoCraft for my 2021 F250 Diesel for warranty purposes (drive train is 5 years). When I looked up qualified diesel oil meeting the Ford requirements, Shell Rotella was all over in terms of standard, semi-syn, and full syn. To top it off, Shell Rotella Syn picks up the engine warranty when the Ford warranty expires up to 15YR or 500,000 miles. WOW, I was sold. Don't forget to register for the warranty if you buy this oil.

Rotella T6 is for me, the ultimate multi viscosity synthetic oil .

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.
