Tying to fill the oil on my Grandsons 1998 jeep cherokee. It just runs out wiyh about a cup input.

Gasket/O-ring bad on the oil fill cap. The fan is throwing it around where you've found the excess.

1.) Open 2006 Jeep Grand Cherokee Glove Box, remove the 2006 Jeep Grand Cherokee owners Manual from glove box. Open owners manual to index page, locate oil filter page.

2.) Secure 2006 Jeep Grand Cherokee from moving fowards or backwards by blocking wheels in front and back which will NOT allow movement of said 2006 Jeep Grand Cherokee.

Using a small person of average build, average height, average weight, average intelligence, average physical appearance, move average said person with said average features of above near the 2006 Jeep Grand Cherokee, instruct said person to physically crawl under vehicle while laying on said person backside, (**** scraping on average dirty ground or average dirty filthy oil filled garage floor filled with oil filled kitty litter. Hand said average person an average shop light with an average wallmart brand soft white light bulb, light bulb will bo out very soon so move to next step ASAP. view engine while calling out all massive oil leaks INCLUDING a dirty oil caked oil filter.

Congradulations!
You found it when a black oil droplet drips from the oil filter into said average oil filled hair of said average person!

Well kev , if he had it serviced at a quicky lube type oil changing place , chances are they did not tighten the oil plug very tight... and it fell out....
either that , or he got a piece of highway shrapnel thru the side of his oil pan....

should hold six quarts...just to be sure, add five, run it and then re-check.
It's good to fill the filter before you put it on...doesn't need to be "full full" but just pour some in it, tap it on the ground a few times and add more...helps priming after oil change.

oil pressure is mechanically controlled by a valve inside oil pump. if it is not leaking it is ok to drive to have it replaced. mainly used as input to computer and for your gauge

Assuming that the transmission is a automatic, you fill it through the transmission dip stick tube. Just make sure you do not overfill it.

may be oil leaking and burning on manifold,could be small coolant leak but u would smell the coolant check valve covers maybe leakin,intake,breathers?????

yes you should remove the access. This will cause the engine to drown in a sense and have to fight. It is always safe to put in not enough to too much. You onlt have a certain amount of oil that can be placed in the pan before it runs up into your cylinder heads and can break the seal on the gasket. Then you would have to pay to get the cylinder head gasket replaced.

does it have the 4.0L motor ? if so open the hood stand off to the side where the exhaust bots to the head and have some one rev it up quick if its coming fron under the hood by the engine the exhaust manifol is cracked. The 4.0L jeeps have had lots of problems with this.
