Greetings Everyone,
First time poster here, but I have been on the site and found some useful information several times before. I have a 2015 Colorado pickup (49,000 miles) with the 3.6L V6. It is a GDI engine, which I know can mean increased fuel dilution. I have a 20 minute drive to and from work each day. In the cold Michigan winter, I have often suspected that 20 mins might not be enough time for fuel in the oil to burn off. My OLM must suspect the same, as it gets down to 10% or so after about 4,500 miles. Note, I rarely idle the vehicle for more than a minute or two. I decided to get a UOA to see how things would look.
Forgive me, as I did read the thread on how to post UOA's, but I seem to be struggling with the "code" method. I will simply summarize, as follows:
Oil is 5w-30 Mobil 1 EP, 5,000 miles on the oil
Fuel % is 2.5, "should be" below 2
SUS viscosity at 210F is 52.0, should be 55-63
cSt viscosity at 100C is 7.87, should be 8.8-11.3
Flashpoint is 335, should be >385
Everything else seemed normal. The comments on the OUA indicated the fuel dilution was beyond what is normally attributed to short trips, but that the engine was "wearing fine" and the fuel therefore doesn't seem to be causing damage. It warned me to make sure my oil level doesn't rise (I got ~6 quarts out on the last change). It concluded a 5k interval was fine to stick with, and that it was "overall good".
Obviously those comments made me feel better, but I am curious if some of you would be alarmed by any of those metrics. I am very picky about taking good care of my vehicles, so I want to do right. I am new to the UOA world, and would appreciate any input.
Thanks!
