ok.
i have often thought that i could hear and/or feel a slight 'lope' or stumble in the engine's rhythm. now i know why, i guess.

i did both dry and wet readings twice with 6~8 spins each and the numbers were within 2~5psi both times for all cylinders. (i think the meter i borrowed from a friend is a harbor freight type and not a proper professional 'TOOL' per-se) my engine gets regular revs above 3k rpm, Virginia highways have long mountain/hill climbs a-plenty.

does the decent compression on the other 4 cylinders explain my avg mileage holding above 20mpg on the highways? does using too much oil do something to the readings? i used a full teaspoons worth of oil in each for the wet reading, i thought that what i read about using, now im second-guessing myself.
