The truck has 97,172 Miles on it. There are 6,776 Miles on this Shell T6 15w-40. I added 1 quart of Shell T6 5w-40 over this mileage.
I hauled my truck camper around 2,500 Miles on this oil on a trip to TX from MO. The GVWR was a bit over 13,000 lbs when loaded up for that trip. All the other miles are empty around 8,720 lbs with the wife & I in the truck. I ended up being about 1 qt below the full line when I changed out the oil. The results are not too bad for being a commercial use truck hauling heavy GN for the first 75K before I bought it!
