I'll admit I know very little about engines but I don't see how it can make much difference, where exactly are these carbon deposits meant to be sitting? I guess your capacity could be reduced by 0.01cm3 if there was a layer on top of the pistons?



I bet the cat was cold in the first readings they took compared to being red hot after running for over an hour.
