Compression
Well, from those numbers(thanks!) It looks like I'm 3 psi above spec on two cylinders. I'd guess that the individual doing the test made sufficient inconsistencies to account for that... Still, seems high after 185K!
Carbon buildup could cause that, no?
BTW, California98Civic, I've just been reading your WAI thread- I have a hunch it will prove very helpful to me in AK. I consistently note 10% loss or worse on my work truck in winter vs. summer- same tires. I suppose There is an increase in idle time for car warm ups though, and rarely extra rolling resistance from snow. Also, In the VX, I've noted warm days make it seem easier to stay in lean burn... but then... less air density could be a factor there... I'll throw out my conjecture and just say I can count on 1.15mpg...
