this was my first full OCI with full E85. i run E85 24/7, current ethanol content around 80%. ran it short to get a base line. this OCI had more than the normal amount of WOT 4th gear pulls. in the process of remote tuning, and try to diag a boost issues that only arises at full boost and high RPM. i'm guessing that's where some of the higher wear numbers are coming from. i was bit nervous when i drained the oil, because it smelled of straight up ethanol. but everything looks to be in order. i'm going to go out to 3K per their recommendation. (400whp).
COmments:
A full run on E85 didn't affect the oils physical properties to any noticeable extent. The viscosity is well within range for 0/40 and the insolubles level shows a low amount of oxidized solids built up in the oil. E85 use shouldn't directly impact wear metals, but the increased power could lead to wear. Metals are a little higher than we've seen in the past after a shorter oil run, but nothing inceased enough suspect poor wear or a problem, either. The TBN is very strong thanks to the short run, Give 3000 miles a try for the next run.

i noticed the unverisal averages changed since my last UOA, so i threw them in there. is that normal in just an eight month period? some of them fell by half.
