How much over the oil fill mark is safe?

I just had my Lincol Zepheyr oil and filter changed, and when I went to a local parking lot I didnt notice any drips of oil under the car so I know the plug was tightened and the filter also, how ever when I pulled out the dip stick it was about a little over a quarter of an inch on the fill line, is this OK or should about a half quart taken out, I really dont like to go back to those quick change oil places? thanks if anyone knowsHow much over the oil fill mark is safe?It's difficult to say for sure if this is too high or not. The critical point is if it's high enough for the crankshaft to hit the oil as it rotates. If this happens, the oil will become aerated, and it's lubricating ability would be compromised. Inadequate oil pressure would result. So if you want to take a chance on your engine being ruined, just to avoid going back to the %26quot;quick change oil place%26quot; you shouldn't have taken it to the first place, feel free to leave it the way it is, and I'm sure that a real mechanic will be happy to replace your engine for a few thousand dollars, if need be.How much over the oil fill mark is safe?you will be ok a quarter of an inch on the stick is not very much just an estimate about a third of a quart to a half there is plenty of room for that in the engine if you see drips under it then its to much but I think your fineHow much over the oil fill mark is safe?if its only a lil over it will be fine. if its over a quart over it will need to be drained because that would be too much pressure for your oil pumpHow much over the oil fill mark is safe?That's a good Question and worthy of some understanding.When you put oil in the reservoir of your car which is a low pressure area at roughly up to about 15-25psi the object is to lubricate and cool the mechanical surfaces within the cam shaft area as well as siphoning the oil up rods to spill out on the head plane so your moving surfaces have a long life. It is really a complicated piece of machinery so anything you can do to maintain optimal slip will prolong your engines life. While some people may disagree on how much is too much having too little is far worse. If you are about a half quart above the line it probably will not affect the engine in any bad way after all when the engine is on it is sucking and churning the oil on all the surfaces it can.The only way to be sure of whether it is too much is to check the engine pressure%26gt; I once got a car from a woman that had 5 quarts too much oil and you might ask how that was so but it all does with being in a foreign country and not speaking the language.I drained the oil and could not believe my eyes this did cause engine problems. I don't think you have anything to worry about but make sure they stick closer to the actual capacity limit because with today's faster and hotter burning engines it may cause premature failure of seals down the road but i think you will be ok till next oil change. something that i do to make sure of good engine slip is to once a year add a quart of super slippery oil like slick 50 and this will at least give you an edge in the event you have low pressure oil situation. So don't worry so much it will be fine but just watch the place you have it done at If it does bother you it would take a moment for it to be sucked back out %26quot; the way they probably changed it anyway%26quot; at the place that did it. Honestly I would worry so much you can always call a dealer and ask if you need to.
