As usual my sense of scale being so utterly messed up has caused problems. So i changed my oil and over filled it. Not alot mind you but on the stick it seems to be up to/just below the D on "DO NOT OVERFILL" now after i did this it sounds different especially on startup. Is there anything bad that will come out of this or will it just be something i can live with. And before people say, no, it won't burn off. my XJ does NOT burn oil in the slightest.
