If you have a ticking, slapping, knocking, squeaking noise the answer from the dealer is, "that's normal". If the car is out of warranty the classification of the noise changes to "that's $1,500", followed by the phone call that changes the noise to, "that's $2,000", sometimes followed by the follow up call, "that's $5,000". You have to have some sympathy for the service writer. A new car is a lot more complicated than a vacuum cleaner. A vacuum cleaner does not have a hood release or any of those other complicated things like a battery or a spare tire.
Overfill of oil.. What happens?

My 408 with the dual filters/cooler has a capacity of 7.5qts and we fill it with 8 even. My "rule of thumb" taken from the shade tree bible is simple....after driving it...leave it at idle on level ground...pull the dipstick and if there are bubbles or foam...you got too much oil in it....if not your OK...
That's the problem, you have to refill it.
Oh, sorry.
The reason GM recommends adding a quart to the Corvette is at high rpm with the standard fill you will only have 1 quart of oil in the pan the rest is in the upper engine.
The only time that you will need a windage tray is when you consistently run over 6000 rpm. Under 6000 rpm the oil will not foam.
I solved all of these problems by using a deep sump 10 quart pan with oil cooler it holds 12 quarts. The engine has a windage tray plus a crank scrapper and trap doors to keep oil under the pickup under acceleration.
I overfill all of my daily drivers my 4.0 V6 calls for 4.5 and I always dump 5 quarts in it. Since it won't wind high enough to foam the oil it is like patman said.

Get the dealer to take out the extra oil, if they don't listen become a hardass and make them do it, if they still don't listen hire a lawyer and sue them and then sue them for lost wages and court fees! Then never go to the dealership again!!!
My altima said it took 4 1/4 quarts of oil after oil change and new oil filter, but I put 4 in and it was above the full mark by a little bit. Weird, because I let it drain for a good hour or two. It didn't seem to hurt anything though.
My F150 manual says 6 qts. It takes 6.75 qts. to get it to the full line on the dipstick. I keep it at the full line. I always fill the oil fiter prior to starting the engine as well.
I have never been a fan of over filling. I am of the opinion that there is a bit of capacity built in to handle a small amount of overfill, but when you consider that when you fill the car with oil, it has normally cooled down, so the level will be lower than when its hot which will already mean that by the time its at operating temp it is affectively overfilled. Thus overfilling when cool will result in a substantial overfill when hot due to oil expansion.
That is why my Opel/GM states that the level must be checked when the car has stood for 5 minutes after a good drive.
Based on this I in fact under fill by 200ml (3,8l in total), so when the car is hot, its spot on the full mark.

1/2 a quart of oil won't hurt.
Alot of oil pans have a 'baffle' inside to keep the oil in place.

Hey, I have the 3.1L as well, also takes the 4.5 or 4.6 qts. I have seen both amounts listed in different manuals. I was thinking the same, because I always buy the big jug, but am starting to think to just dump it all in. What filter do you buy?? I get the NAPA golds, but what model would be the oversized one? I also looking for oversized one as well
The reason you should wait awhile after you shut off the engine is to wait on the oil to drain down into the pan.Quote:

The oil will expand very little but once the engine is running a lot of oil is up in the engine and the level will be much lower than when you checked it with the engine off.
If you hang out on some forums where guy's have Modified engines you will see guy's posting about oil pressure problems this is because 3 quarts will be up in the engine at high rpm and if you corner or accelerate the small amount of oil left will flow away from the pickup. That is why GM advices overfilling a Corvette when driving it hard.
Under normal driving it is not a problem.
