Viscosity at 100c 9.6



I put in Mobil 1 ESP Formula 5w30 this time, along with a Fram Ultra filter. It's nice to see that the fuel dilution is down (it was 2% on the first interval) although I do believe it's probably still close to 1% considering the 9.6 cst viscosity at 100c (M1 5w30 starts out at 11.0). Iron is way down (was 48 on the first one), copper went down (was 36) as well as silicon (it was 124), but I'm sure it'll be a few more intervals before the break in materials come down to a more steady level.

I will run this oil out to no more than about 5 or 6k, or the late fall, whichever comes first.

Not enough Zink. Gonna ruin that flat tappet cam.
That's a Corvette joke...
