I am wondering how much extra oil is "overfill" (how much in excess of 6 qt, that is), and what the risk is.
I had my oil changed and I believe they shorted me... I get the oil done every 1500-2000, so not the first time it's happened. My local place knows to give me 6 qt, but I wasn't there.
I returned very shortly and said to make sure it was full. "Don't want to over fill". Well I've heard that under-filling might be worse, so I made certain they had the level up to the "full" mark on the dipstick.
So how much over fill is overfill, and what are the consequences? Is there some faulty info out there about oil capacity?
Much obliged,
D Frank
