I'm starting to notice a bit of roughness when at idle or when rolling very slowly. I'm running just fine when on the gas. How can I tell if it's time for a tune-up? It's a '99 328i automatic with 80K miles.
Also, just had an oil change (could that have something to do with it, or was that just a timing coincidence?). The boneheads put natual oil in the thing! My original plan was to run it for 3K miles and then get it changed back to synthitic. Is that a good plan?
And, when I check my dipstick, I notice the oil is reading overfull by about half a centameter, probably. Also, I noticed a little oil mess on my engine. It looks like a bit of oil sprayed out of the dipstick hole of something. It that possible? That doesn't sound good.
