Below is the 1st UOA from my new truck. This is the 1st UOA that I have done since it was purchased new. Out of the 7952 miles on this sample, 2,296 miles were towing a 10k toyhauler. I was concerned with the oil thickening since the oil temp has spiked to 250 degrees at times when towing. Normal towing oil temp is between 220 and 230. Oil filter and Air filter was Wix. Everyday driving for this vehicle is 30 miles each way all highway. Universal Averages are on the right which were at 5900 miles. After this oil changed I switched to Rotella T 10w30 since I was installing a Frantz bypass filter that I had on my previous truck. I will sample again at 10k since it will have 3 quarts of makeup oil. TBN was not tested since this was a baseline test before the bypass filter.
This motor does not have MDS and GVWR of 14,000 lbs or more is advised to use a 5w30 oil. I will be switching back to Amsoil after a run of Rotella for comparison.
