Greeting, this is my first post.
I have a problem with excessive oil consumption and blue/white smoke intermittent on start-up. Been to the dealership 6 times already and they've just complete the second oil consumption survey. I'm using about a quart and a third for about 2000 miles (1.5 litres over 3500 kms.). So far they've change 1 valve stem seal on cylinder #4. While this did cut some of my smoke issues for a while it seems to be starting up again as well I did not notice any reduction in my oil consumption. I have a feeling that there is a problem with all the valve stem seals straight out of production. Whether it's the seals themselves or installation during production, I believe this is where the problem lies. I've made some inquiries and Dodge has come up with what they say are oil consumption guidelines that seem a little excessive to me. The thing is, since 2007 I've had 5 dodge pickups in my household and this is the only one that has had this problem. So I have a hard time believing this is normal. Does anyone have any experience with this issue? Sorry this may have been posted twice. I originally asked a question, had to register and it disappeared. When I register and posted, I saw my original question. My apologies as a new member.

 

Only suggestion I can offer is maybe have your oil analyzed by a lab. Somebody like Blackstone labs. They can detect trace amounts of different materials in the oil that may point to certain parts like bearing material, seals, etc.

 

some say it has to do with running on 4 cylinders. i run on 8 all the time and no dif in mileage. seems to be smoother.
