Here's my latest analysis for all to see. Oil was used for 4,878 miles over four months and the computer was at 29% remaining. Engine time was 203 hrs with 61 @ idle (30%). The lie-o-meter said I averaged 16.7mpg, but it's generally about 1mpg higher than hand calculations.

I'm mildly surprised and very happy with these results. No fuel dilution. The marginal viscosity results from my first sample had me a bit worried on this sample with the increased idle time, but it stayed within spec. The TBN is still good and no excessive wear metals. I guess I could easily go a full cycle on this oil.

 

good info.
