joemd60 It is obvious the jeep is not burning oil nor leaking from the rear main seal, it was checked and re-checked it is not wet around there or anywhere for that matter. that concludes and it is obvious whomever is changing the oil at the shop is not adding enough oil, if my last post was read thoroughly it said I had 2700 miles when it went in the shop.
As for the 1/4 of the blue book value of my jeep, I will send you the tires and rims. When you come up with the other 11K you can have the rest of the jeep.

BlackJeepoftheFamily Did you check the rear main? Look at the bottom bolt where the aluminum plate bolts to the transmission. It's a subtle leak because usually drips off WHILE you are driving. When it's not running, there's not enough oil in that area to really leak. My 99 Sahara had the rear main replace but it never dripped on the ground.

Seriously, I have a '07 Taurus with 29,xxx miles with a rear main leak that loses 1/2 quart of oil in about 2,000 miles but never drips on the ground. You can just see the oil on the aluminum plate after you've driven it. Mechanic at the dealer says he can't see the leak because by the time they get the car on the lift, it doesn't look like it's leaking. Still 1/2 quart in 2,000 miles is NOT acceptable to me. My Jeep now has 74,xxx miles and doesn't use a drop between oil changes.

rrich You can try the suggestions here - if they work, great.

If they don't, you can have the engine totally rebuilt for $2000 or so - that might help.

Then you'd save $2.50 every 1700 miles.

Or better yet - sell it to me - I'll pay you 1/4 Blue Book value - we already know it consumes way too much oil.

joemd60 Well strange as it may seem, I only had about 2700 miles on the oil when I dropped it off. The jeep burned 0 oil between that so I am happy.

I am just driving it and trying not to worry about it. Although while I am saving for a lift and install costs amongst other things I want to do to my jeep. I have temporarily put everything on hold until I find the oil problem.

MOz I know it's a Jeep and not a Ford, but perhaps this can serve as some industry reference:
According to Ford's warranty guideline (as I was told one day when I replaced a 351M engine in my 90 Bronco)...

Acceptable oil loss for a "NEW" motor is 1 quart for 2000 miles. Anything more is considered excessive and they would cover the warranty to rebuild it.

How much and how often do you add? My oil rarely makes 3k. I change it every 3 months or 3k whichever comes first.

I hope to get off road soon, need to take care of moving expenses first. And hopefully I find the solution to the disappearing oil soon.

I'm pretty sure I have read through all the posts and he has stated that his dad told him to drive it the way it is. There may have been some confusion on my part weither he is going to fix it or drive it the way it is.

stevens243 I'm just gonna throw in my 2 cents here.

I've owned like 20 vehicles.

Only 1 of them went thru any real amount oil on a regular basis (the 66 chevy that sucked the rear main on the I 80 won't count here).

Had a 69 Pontiac that somehow "lost" oil (yeah, an old pontiac that didn't leak, what are the odds)? That car didn't really smoke too bad, but it would go thru a quart every 1500or so. Drove me NUTS!

The rest of them don't or never used much more that a 16th of an inch on the dipstick in 3-5k miles.

So, I call that "normal".

Oil doesn't just disappear. It leaks, burns, turns up in the radiator but it's doesn't just "go away".

joemd60 That is one thing I am going to look at closely when I change the oil. There are no spots on the ground, if there were this jeep would be in the garage getting fixed.
05-06-2009 07:35 AM
flattietj u are not except for most loose their oil at the rear main seal
05-06-2009 07:29 AM
joemd60 Well my friend, it is what is. Unfortunately that is the card that was dealt to me. I drove my jeep for 1.5 years without having to add. And now at 40k it requires a qt. Between changes. So let's look at my options, 1. Spend a fortune trying to find the problem. 2. Sell it thinking the problem is solved until the next buyer figures out why I sold. Or 3. Drive it and live with it. The 3rd option seems to make the most sense. None of us have a crystal ball to predict the future, if I knew my jeep was going to start needing oil between changes I would have not bought it. Sorry I don't mean to rant, I appreciate everyone's response. This thread is turning into whose jeep uses oil between changes and whose does not. Maybe Mods we could turn this into poll as well. With all the members on this forum I would be willing to bet I am not the only one with this problem.

flattietj my 1990 cummins uses less oil than that motor and it burns oil for fuel........i change my oil in my jeep twice a year with no consumption.......

PT Barnum was right!
oil companies should not add them if they worked, because they have no place in a perfectly operating vehicle.

For me, I will never EVER run an oil additive in the modern superb multi-weight engine oils (typically Valvoline) I run.

jerry, is the way it acts on gears gonna be different than in your engine, since that is all pressurized oil through passages, not simply splashed around?

all i know is it helped oil consumption for my prior jeep. although, i am not a fan of many additives, bandaids, or quick fixes, i found this stuff to work well, and reduce oil consumption even while decreasing the use of it.

Thanks Spanky I will, synthetic oil is more for longevity. In the years I have been driving, I am anal when it comes to oil changes that is why I have made the 100,000 mile plus club without any major engine trouble. And I never used synthetic oil in any of my vehicles, not that I am downing it. It is too expensive when it comes to 6 quarts it is cheaper just to add if need be. I am having the oil changed again in a couple of weeks. When she is on the lift we will go through it with a fine tooth comb. In the meantime I will keep you guys posted on this. What I like about my Mechanic, is he gives my jeep a second eye when he is changing the oil so I trust him.

I have been talking with my StepDad about this also. He was not to keen on the idea of lucas. He holds his ground and said to just drive it and keep up with the oil changes.

Since synthetic flows more easily through tiny oil passage ways like bad rings, I'd bet big $$$ without hesitation oil consumption will go up slightly when compared to a mineral based oil.

Changing to a synthetic certainly won't decrease consumption.
