I was expecting this UOA to show high fuel like in UOA #2 as it was driven during the same time of year and for nearly the same mileage. However, I did take this sample directly after a 70ish mile commute, so perhaps the excess fuel evaporated out of the oil on the drive home. With the exception of a low flash point, this is a rather boring (Yay!) UOA. I'd like to get the flash point up into the targeted area so I'm dropping the OCI to 8,500 and seeing how it fares. As I mentioned in this thread Mazda decreased the maximum OCI from 10k to 7.5k and I suspect that's due to fuel dilution.
OCI history is as follows:
0 - 1,169 - Factory Fill
1,169 - 10,120 - Mag1 0w20
10,120 - 19,949 - Mobil Super Syn 0w20
19,949 - 30,031 - Mobil 1 EP 0w20
30,031 - 39,486 - SynPower 0w20
39,486 - Present - SynPower 0w20
