Here is my first UOA post, its a bit hard to get this to look good so bare with me. The truck has 129k on it and I put over 14k on the oil. I did change the filter at 7500 miles. 2qts of make up oil was M1 0w-30AFE and the other was Amsoil. I have been using Amsoil with the same OCI for several years now. The trucks air box has one stripped bolt, no extra silicon though. My climate ranges from 15 to 115 degrees and lots of dust, I drive off road almost every weekend. 34 mile round trip commutes the rest of the time. Now that I'm confident Amsoil works well in my truck I'm going back to M1 or similar at 10k OCI or so due to the price. All comments welcome. The factory report looks so good but I cant get it to load on my computer.
05 GM 5.3L V-8MAKE/MODEL: OIL TYPE & GRADE: Amsoil 5W/30
UNITGasoline (Unleaded)FUEL TYPE: OIL USE INTERVAL: 14,145 Miles
COMMENTS: This engine looks great. Universal averages show typical wear after 5,800 miles on the oil. This oil was in use longer, though it seems like you took good care of things during the oil run, adding oil when you needed to and changing the oil filter to keep in-solubles nice and low. And things worked out for you really well. In fact, we think your next oil run can probably be a little longer. No contamination was found and the TBN is good at 2.5. Anything less than 1.0 is considered low for extended use. Try up to 16,000 miles for next time. Nice engine!
