Black tailpipes are usually carbon deposits from the burning of Gasoline. The richer a car runs, the blacker the tips..

HEHE, I was editing my post as you posted this. I agree, I was being sarcastic.


Edit again: I did go back and read the OPs post though, and he has added in oil. I lost sight of the original post and for some reason thought this thread was about black tail pipes = burning oil. Think I misunderstood.

Hoping the mods can clear up the "junk" in this thread.
I know for certain the VQ37 is loosing oil, not necessarily burning it, but def loosing...
All to familiar for me...:shakes head:

And you know this how? If an engine is losing oil and NOT burning it through the combustion chamber, it is leaking it. Fix the leak. Pretty simple. Not all of the tens of thousands of VQ37 motors are consuming oil.

I had to check to make sure i was in the right forum after trying to read the previous page's posts! Who let the trolls in here?
So back to the issue... less than a quart per oil change interval is ok, but more would be indicative of a oil-burning issue?

No, Not really..... Very few manufacturers will give you the time of day if you're not burning more than a quart/1000 miles. Chevy (for the Corvette) even has a published bulletin that says 1 qt per 500 miles is acceptable if used in an aggressive manner (aggressive being defined as operation above 3000RPM's...LOL). A quart between changes, or even 2 would not be considered excessive enough to warrant correction with most all companies...
When you get into the serious usage area they will do a monitored test by documenting miles and sealing your oil fill to determine true usage..

(Just ignore the idiot trolls)

just checked mine. 6000 miles and 150 from next change. It's slightly overfilled still.

Proper action taken. HEre's the new "clean" thread. Please keep it on topic. Thanks. :tiphat:
