Better than most oil

I Use Shell Rotella Synthetic Blend 15W-40 in my Wakesurf boat. The engines in these boats take a beating. Heavy loads at high RPM's, (3000) and only moving at 10 MPH, need an oil than can withstand the heat! Looking at upgrading to Full Synthetic on my next Oil & Filter Change

I run t5 in my high output daily Cummins and it definitely shows up for the job. 96k on the engine and she doesn’t burn a drop even at the 3500k oil change mark. In 20 degrees she’ll start right up with low top end noise. Keeps her running cool. Definitely thinking about going to t6 next oil change!

I used the Rotella products for decades in my trucking companies. ( & my personal diesel pickups.) In Millions of miles for semi-trucks, using oil testing labs to continually monitor oils, I was able to extend oil drain intervals significantly. In all those years I NEVER had ONE oil related failure or indication!! One such truck I took out of commercial service & continued to use it for personal use for 7 more years. I sold it with 972k miles, & Still had never needed to do an engine overhaul!! ( that was with NON synthetic oil ) Now that synthetics are available, my personal trucks use this exclusively!! I grew up in Northern NY, on the Canadian border, & value the cold weather performance of synthetics even more.

First time I ever put this in my 2006 vw jetta with the Diesel engine with 220,000 miles and I've never heard the engine idle so quiet at highway speeds and with the low ash it gives, I never have to worry about blocking up my cat like the other oils

I've been using t5/t6 oil since I bought my diesel truck. I have had the truck for a little over a year with no problems. Sounds crazy but the way the truck ran after a fresh oil change using t5 was noticeable. I have a landscape/lawncare business. My truck gets driven hard, and I put a lot of miles on her every year. Rotella stands the hard wear and tear. Will always use Rotella on my vehicle.

Why we can not find it the stores and at truck stops I have a semi and I had to chevron in my truck because the TA truck stop can’t get it and can’t find it in stores

Been using T5 in my cars and trucks and farm tractors for over 15 years and have never had any problems, fuel mileage is great and even better in the trucks and farm tractors.

I have been using T5 for the past 35,000 miles and the engine runs smooth from the moment the oil is fresh until the moment before an oil change. High quality oil! I even run it in my 65 F100 Gasser!

I have a small farm, and I always service my equipment every January. Well this years could not find any Rotella anywhere. Had to switch to Delo just to get my equipment back and running. This made me very sad.
