Much improved over the previous UOA. I'm pretty sure my suspicion that high fuel in the previous UOA was caused by winter driving is correct. I do think that dropping the OCI down to 8k miles is probably optimal, but, going to 10k miles certainly won't hurt the engine. With that being said, I don't trust the OLM system. Once again, this sample was taken with an OLM reading either 50 or 60% remaining. I did contact Mazda to find out about their algorithm and they actually seem to be intrigued by the lack of depreciation on my OLM so that's something we're now digging into.
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 - Present - SynPower 0w20
