I was really hoping to see no fuel in the sample this time (last time was 5%) but it went the other way!
I put in more 0w20 AFE and did not change the filter, but my original plan was to switch to either 0w20 EP or AP on the next interval after this one. Now I'm wondering if I'm better off to just stick with shorter intervals and cheaper conventional oil. I really don't want to spend a lot of money looking into the cause of this excess fuel, as the car really isn't worth much at all and just needs to last me 4 more years (and then I will be retired so we can get away with just the BMW and Corvette) The car still runs great, there is no hard starting problem (like there was a few years ago when I had a lot of fuel in the oil) so if it weren't for this UOA I would never even know there was any issue at all. Considering the high fuel and low viscosity, wear numbers are excellent!
I had done back to back doses of Gumout Regane over two full tankfulls at the start of this interval to try to lower the fuel (which has worked for me before) and I will try it again this time.
