I'm not surprised by this statement, but could you go into detail? For instance, no wear difference between a slippery synthetic and a dino? Not even wear caused by cold start-ups?

BTW, what does "TBN" mean?

Thanks.

I know it's hard to believe, but its true. With my car (and my maintenance schedules), there is no difference in the PPM rate of the typical wear metals (aluminum, chromium, iron, copper, etc.) for dino or synthetic. This is true even comparing winter to summer, (very) spirited driving vs. highway miles, etc.

TBN - Total Base Number. This is a measure of the amount of "life" left in the oil (additives remaining compared to a base stock).

I'm an engineer - I'm very anal when it comes to data, assumptions, and my car
