i have scan data logs and scope images

but
i was using 2.5 oz diesel to 1 gallon of 87 octane E10
top tier fuel in the summer time

and the stock G10 engine is not a high compression high performance engine

Hmm, interesting, this is opposite what happened in my dodge but I used a very small amount of Veggie oil mixed into a container of E85 as top lube Somewhere in the 1:200 range.

I always figure less is more, in this case I must have been right.
