I think I know why the fuel dilution occurred. Has to do with ultra short trips in the morning to walk my dog - changed my practice in June. Just surprised because I do multiple highway runs during the week (30 minutes round trip at highway speeds). Also, might explain why the other numbers...

I was surprised that the viscosity was not lower, especially compared with the last UOA also using M1 0w30AFE for a shorter run with no fuel dilution. And similarly for some of the protective additives too. Is this just normal variation in measurement?

Just posted my latest UOA. Hmmm…may have to bump up to 0w40🤣

Very true. I get about 18 hwy and 14 city. I tend to drive 75 to 80 highway. Survey from From Club Lexus GX460 owners
