Note: PF48 oil filter is missing anti-drainback valve. Please read lab comments:
The most unusual find in this report was the 2.3% fuel dilution. It's possible fuel came from
idling or starting the engine right before sampling, so we're not going to get too excited at this point, though
if fuel increases next time, we may start to wonder. The viscosity of this oil was lower than the 5W/30 you
guessed it might be. It's probably a 5W/20. The high wear and silicon are wear-in materials and should
improve next time. Universal averages show normal wear after a 5,200 mile oil run. Go 6,000 miles next oil.
