Agreed,

I just made the switch, and then wanted to get a baseline oil analysis, so I switched early, as I was eager for results. Overall, I guess 22ppm of iron isnt that great at 3600 miles, but Im sure Id have the same using a dino oil, unless the higher cold viscosity protects a little better given the tolerances in the engine.

I think Im going to go back to synthetic, although I might do an analysis on dino oil to see how it stacks up...
