Hello all!

Great forum w/lots of good info. I own an '11 V sedan which has about 15K on it, i bought it used w/about 12k on it about 5 mo's ago. Today when i was getting gas i checked the oil and when I pulled the dipstick out a few small whisps of oil smoke came out of the dipstick tube. Is this fairly normal (I can't say that I've experienced it with other vehicles) or is it something I should be worried about? The car is not using a lot of oil (about 1/2 quart in the 3000 miles I have put on it) and has what I think is pretty normal oil pressure 30-35 psi at idle and about 40-45 cruising after the engine is warmed up and it runs consistently at about 210 degrees.

Thanks!

It might be blow-by, if it was running at the time. It's under warranty, so it's not a problem then. The engine's own system should take care of that too.

nah, it wasn't running. Just shut it off, pumped the gas & then pulled the stick, wasn't a lot of smoke by any means just a few whisps coming out. I live pretty far from the dealer but I'm gonna bring it it soon to have the car checked & serviced and I'll be sure to ask them about it.

I don't know if the diff oil has ever been changed (as I've seen recommended) is that something I should definitely have them do?

I think that's been brought up before. I don't remember it being a big deal...

The smoke from the crankcase or changing the diff oil? Thx BigJim

I'm still trying to find past threads. Maybe someone will chime in...

I searched it after you mentioned that & found a couple of threads that said it was normal after it had been driven for awhile. Just kinda freaked me out as I can't remember seeing it before with other cars.

Yeah, as long as it isn't a ton while running you should be fine. An old friend of mine toasted a ring land in his LT1 and it blew smoke out the breather like a mosquito fogging truck.

Maybe just normal crankcase vapor?

When I was much younger and serviced my own cars, I would see some smoke billowing out after running the car briefly and then opening the oil FILL CAP (which would be equivalent to your dipstick incident) often and it was never an issue.
When I check the oil on my lawn tractor with the engine warm, I often see smoke billowing, not that I'm comparing our Vs to a lawn tractor.
It's probably fine. Wouldn't worry too much.

Good morning halonut,

This looks like a good plan if you aren't too concerned about the smoke you saw - I am unable to provide technical advice, but the feedback from forum members seems to be unanimous. If you wanted to give us an update after you go in for a service visit, that'd be great! In the meantime, if we can assist with anything don't hesitate to send us a private message here on the forum with any other questions you may have.

All the best,
