I got my UOA today. The overall severity of the report is showing normal.
My fuel contamination has dropped from 3.6% (High end of ABNORMAL), Viscosity 9.0 (Critical), to 1.8% (High end of NORMAL),
Here are a few factors:
1. The only change that I made was adding the Amsoil gasoline fuel treatment. This may have helped with a sticky “leaky” injector? I don’t know…….
2. Even though this is my daily driver, the UOA only had 944 miles and approximately 90 days on this interval.
Conclusion: I have no signs of coolant in my oil, which is a good thing. I have no idea how my coolant problem took care of itself without making any changes. I’m going to add another bottle of the Amsoil gasoline treatment to see if I can totally eliminate fuel in my oil. At this rate, I feel safe changing the oil at 4 month intervals and resample accordingly.
