Burning oil when switching to 8 cyl mode

Burning oil when switching to 8 cyl mode
I notice when cruising on the expressway at about 70-75 mph for a few miles that when it switches to 8 cyl mode my exhaust blows out a big puff of blue smoke. Anyone ever experience this?? My car also goes through a quart of oil every 1500-2000 miles.

Yes disable DOD as soon as possible!
Youll lose about 1-2 mpg on the highway, city stayed the same for me about because its rarely in 4 cyl mode then anyways..
When I had 4 cyl mode I would burn a quart or so every 5k, sometimes a little more..
I disabled DOD about a month or so ago, and got an oil change the day before I disabled it..I have not lost any oil since...Ive put on I think roughly 3.5k to 4k miles since.

Mine just started to do this and since I'm under gmpp still till the end of the month it's going to the dealer. I saw a post involving something about this issue that gm actually acknowledges this problem. Found the pdf for it. http://ww2.justanswer.com/uploads/Bl...alve_cover.pdf

I just posted this on clubgp, but I'll post again anyway, with at least my experiences and I know quite a few other people on this board:
"If you're using Mobil 1, it's known to burn faster than any other synthetic on this car (it's also one of the thinnest synthetics to slip through the piston rings). Check the ls1 forums (ls4 sub forum) for more details. Other synthetics seem to burn slower, but yes there is still consumption no matter what on these in 4 cyl mode. Since I switched to Pennzoil Platinum, I consume only 1 qt every 3,500-4,000 miles as opposed to the 2 qts every 2,000 miles when I was using Mobil 1. Just my 2 cents."

I've used Mobil 1 oil exclusively in my Monte SS since 9000 miles... I'm now at just about 109,000 miles...
never burned 1 drop....
my DOD is disabled - has been for the past 5.5 years... 4 months after I bought the car brand new...
it's the DOD causing the issue... NOT the oil....

Thank Goodness for this forum I was wondering why this was happening I run pennsoil and it never fails when the counter gets around 60 percent im a quart low even when i babied it so im guessing dealer or buy a tuner to disable the DOD?
