so a month ago I go to get my oil changed and the bozo puts regular 10-30 in there when I allways only put full sythetic 5-30---so I make him do it again and put the right stuff in this time......now I'm having a slight problem:
well it being a 16 year old car theres bound to be a spot of oil on the garage floor every now and again -- but lately there's been a puddle under there. A puddle that's a good foot accross. not only that but there's about 1/2 quart too much oil in there acording to the dipstick....--my grandpa is an old tracter/farm mechanic and he says that gas is probably leaking into the oil by the means of a misfire or some other way...so today I change the oil myself and make sure that I put the right amount in-but after driving around the town for a few minutes the oil level is a good 1/2 quart to high again...
is he right? how do I find out what is causing the problem?
Normally if fuel is getting into the oil when you drain the oil you will smell the petrol are you sure you put the right amount in i.e. did you fill it run it then let it stand with the engine off before checking it? You have to let it stand to allow all the oil to run from the top of the engine back into the sump.
