Hi,
Link to UOA for M1 0w-40...
M1 0W-40 UOA
This after 3 track days (say 400km total) and around 1000km of road driving. Vehicle is 2001 Mazda Mx5 / Miata. OEM mazda oil filter. Total km on vehicle is approx. 70,000km. At the track it's between 5000rpm and 7200rpm. The road km are just driving to/from various tracks, mostly on the freeway, at say 3000rpm.
UOA looks ok to me. The fuel dilution is a touch odd, but I did idle the car for a while to warm it up before doing the oil change so perhaps that is it.
Looking to extend the drain interval, so perhaps try 5 track days next? What do you think?
Cheers.
