Oil consumption doesn't seem to be dropping off like it should - I compression tested it tonite as well and all seems to be ok - a couple of cylinders seem to need a little throttle, but they all make 160psi (standard pistons + pockets remember)
oil is semi synth 10W40, so not too thin - engine has done about 850 miles now, so rings should be well bedded
plugs are fine too.
I'm sure I've noticed some faint signs of smoke at high RPM too.
am I missing something obvious ? - it is possible a ring or two haven't taken quite right and would give the above symptoms ? - it's the only thing I can think of
Also - would running an engine leaner cause it to burn oil ? - at the mo I've got it set for economy up to site 9 (lambda 1) - I'm sure it's not my imagination but the oil consumption seems to have increased during the last two outings, as the ECU has adapted the fuel...
