How much engine oil is TOO much??

[homchz]

I must have counted wrong, as yesterday I was doing my fisrt oild change on the XJ I bought, and I thought I put 7 in. I put in 6, started the engine, let run to fill the filter, and when I check the stick it was low a quart, but I must have only put 5 in.

Big difference going from a 4cyl to this though.

well, as mentioned it's almost impossible to fill the filter with oil and put it on without loosing that oil.... so that trick is out the window...

Anyways, I always fill about 5.25 qts and then start it for about 30 seconds and stop it and wait 15 ~ 30 minutes (just walk away and do something else or maybe start your cleanup or something) and then when you come back check it and readd as necessary.... I don't think that you can really add 6qts to it as unless you figure out some vacuum pump setup you will not be able to drain all oil from the engine...

Anyways, I try to stay between the marks...

granted you will lose some oil from the return hole (in the center) but a great deal will be absorbed into filter medium and add for a much quicker fill time than if you didnt fill it before hand. the mechanic put it to me by saying any way that you can cut down on dry start is well worth it....also told me to change oil every 2500 miles not 3000......go figure, but I take it to heart and do on all my cars now.....

Well, I dump in a full 6 quarts every time (use up a case, since I change both DD's at once) and both of my XJ's drop smack on the "Full" line. No trouble, no seals dropped, no nothing.

If you are having a slight overage at six quarts (which is spec,) the only thing I can think of is that the rubber seal may be compressing or something and the dipstick is going in a bit farther than it is meant to...

this is getting long winded

I hate to add to the posts on this thread that is already too long for the complexity (or lack thereof) of this issue. However, I will concur with Eagle: Just drain all the oil, making sure it's warm and loose, put the plug and new filter in, fill it with 6 quarts, and start the Jeep. Make sure that you have tightened the filter, and then clean up your garage, because that's actually mor important than a centimeter on a dipstick. I put 6 in mine, and unless you have a massive crater in your oil pan, you should be able to put 6 in too.

Take it easy,

My friend just did the oil on his turbo volvo. Didnt fill up the filter.
Just in case anyone was wondering.:eyes:

Ive never filled the filter with oil prior to putting it on the XJ, but i always fill it first on the dodge. Cummins engine = big filter, that thing holds well over a quart. I dunno if its critical on the turbo engines, but better safe than sorry if ya ask me. Go price a new turbocharger for that thing and you'll fill it too for peace of mind
