Hello. I have a 2006 caravan with the 2.4 engine.I purchased the car new. I change the oil and filter every 3-5 thousand miles and use the recomended 5W-30 oil. Up untill about 44000 miles the engine would use about.5 quart of oil between changes. Gradually the consumption has increased to about one quart every 2,100 miles. The vehicle has about 53,000 miles now.
The engine does not leak, there is no smoke out the tail pipe at start up, nor when driving. There is no increase in fuel consumption. The PVC system functions as the service manual describes. There is no blow by out the crancase vetalation inlet hose. The spark plugs have carbon on them but are not oily. The engine has never been overheated or abused. 80% of driving is 55-60 M.P.H high way. Chryslers response to other owners via ethusiasts web sites who have oil consumption issues with there engines is. One quart per 1,000 miles is OK. If Below 50,000 miles and 1 quart per 750 miles over 50,000 miles is Ok. I have never had a low milege vehicle consume this much oil. Do you have any insight to this problem? Your expertice would be greatly apreciated. Thank you.
