Only once more

I don't want to beat a dead horse, but my 3.8 is burning about a quart every 1200-1300 miles, not enough to get Chrysler to do anything about it, but annoying. Has 46K on it now. Do you think it will level off at this amount or continue to use more? Also have seen a couple of posts indicating synthetic might burn less. Could this be possible? Have always used 5-20 conventional and 3k changes. No leaks-cement driveway is clean.

Can't believe Chrysler won't do anything about a quart every 1200-1300 miles - that's unacceptable! I don't check my oil level that often so if mine burns that much it'll be blowing up shortly! Do you see it inside the tailpipe? Is the PCV clogged? That much oil must mean something else isn't kosher. Am I understanding that it's burned that much all along? (I assume so since you wouldn't expect Chrysler to do anything about it past the 36K warranty)

Lots of states, maybe Feds(?) have laws about how long vehicles have to be within emissions standards. If you're burning that much oil, Chrysler may be on the hook if it throws your emissions out of compliance. Worth looking into IMO.

Here's some federal EPA info: http://www.epa.gov/oms/consumer/warr95fs.txt

Will check PCV. Oil use has increased gradually from about 25K. Just passed Wisconsin emisions test with no problems though. Tailpipe is pretty black but not excessive, nor do I see a lot of blue smoke but then I'm usually in it when starting, will check.

the cat convertor will burn and mask excess oil consumption so its tough to judge from the tail pipe however i recall back in the late eighties/early nineties when fuel injection was becoming popular and more complaints of useing oil (less fuel dilution because of injection verses carb) where common ford considered 1 qt oil per 1500km/900miles as normal usage but not sure about todays standards

Your right. They won't do anything unless you burn more than 1qt. in 1000 miles. How long has it been burning that much oil. Some indicated that syn was burning more. Some went to 5-30 and said it helped. There have been some comments that engines assembled in Mexico were more prone to burn oil. Check your window sticker. It will indicate where the engine and trans were assembled. I have to say that if my 10 Rubi starts to do that it's gone. So far, it doesn't burn any. The engine is listed as United States and the 6spd Germany. My 89 YJ maybe burns a half quart in 6000 miles. Amazing.

I'm probably jumping in here too late, but within the last 12 months (ironically since I left Illinois and moved to California) I have noticed that I burn about a qt about every 4K miles. I just turned 35K this weekend. I never had this problem the first 16 months when I lived in Illinois and do the same driving, but now I find myself checking the oil every few weeks. Maybe it's normal, but a qt every 4K seems to be a lot for just normal wear and tear. Maybe I'm wrong??

Synthetic usually make an oil consumption or leak WORSE, not better. If you want to try anything, try going to a thicker weight oil. No guarantees, though.
