wranglers do not use an actual valve, but the pcv passages tend to get clogged. start there.

Thanks jg, that was my thought also. I checked the air cleaner passages and they are clean.

1 quart of oil between changes is normal. Any manufacture of a naturally aspirated engine will advise that is in normal guide lines. Call your local Chrysler dealer if they are still in buissness and they will advise you the same.

In 45 years of driving, I remember maybe one vehicle that consumed about that, perhaps a quart between oil changes. None of my other many (!) cars and Jeeps ever consumed oil between changes. Not even my TJ with 180,000 miles on it consumes any oil between oil changes.

He also stated that after 1700 miles it used a quart. Not even to 3000 yet, I can only imagine how much it would use after 3000. If the pcv or the engine flush or lucas don't work I'd sell it.

I think you are being a bit extreme. My StepDad is very good around cars, he restored his 67 Mustang and has been fixing his own cars for years. His theory is if there is no smoke, leaks, and the engine oil is not black. ( Which that is the case.)Than take a deep breath relax and drive it. Some vehicles unfortunately will need a quart between changes and it is not totally out of the ordinary.
My jeeps engine is dry and clean, the air cleaner is oil free, and the pcv ports are free and clear. So while I am not completely happy about it, I am also not worried either. The jeep passed inspection without a hitch, and she runs excellant. So I am not going to sell it over this not to mention I am in no position to since I still owe money on it. Also one thing I do is make sure I change oil so it will never see over 3k.

You know jp what makes me laugh is reading a couple of posts here making my jeep out to be heading for the bone yard. It is 1 quart of oil not huge puddles in the driveway. And to be clear it was not quite on the add line I probably could have driven even further before I had to add. Thank you again for your helpful input.

Are you sure your checking the oil right, It should be on level ground when you check it. I've just have never seen a engine consume oil and not smoke. Its not going to fall apart on you though I drove a 85 ranger a round for about 1 year that had bad piston rings and it consumed more than just 1 quart every 1700 miles mine was like 1 quart every 2 or 3 weeks and it smoke like a freight train while doing it. I'd just flush the oil throw some lucas in it and be done with it.

I am going to look at the lucas option. I am not happy with this either but my best option is to just drive it and keep an eye on it. I check the oil where I buy my gas which is flat. I liked the post saying I should sell it.Selling my jeep is not an option nor a solution. Selling something with the intent to mask a problem could come back to bite you in the ass.

Try a good synthetic oil for an oil change and see if it still consumes a quart in 1700 miles.... bet it wont

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.

Before the Lucas was added, the oil had very good "climbing" traits meaning it climbed up the gears well, stayed put, and the oil stayed the original color meaning air was not being mixed into the oil. Then when the Lucas additive was added, the climbing was reduced but more importantly, the oil then started turning a light brown from having air being mixed into it turning it foamy... not what I'd call a good quality for effective lubrication.

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

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.

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.

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.

If Slick 50, STP, Bardall, Bubba's Magic, Lucas, or any of those really made any difference - wouldn't the oil companies add that stuff to their oils to gain a competitive edge?

PT Barnum was right!

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

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.

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.

I think you took my post to heart a little too hard there champ. Look at the facts, you burn a quart every 1700 miles! Not normal AT ALL. Think of how much your going to burn in 3000. There is something wrong internally with your motor or one of your seals or gaskets are not sealing properly causing a leak. Find the source of your problem and fix it.

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".

anyone who has read thru all these posts will know that its at the "diagnosing the problem" step. im pretty sure he realizes its abnormal, and it is a problem by now.
