New to the site. My 2005 has been burning a lot of oil. I have already come across the air cleaner problem and the fact that they just burn oil.
The real problem I have is from a dead start and then WOT the car will jump up then drop to nothing and back to WOT. I didn't look at the tach but I am guessing around 1800-2400 then 600 and back up and down. It also seamed to do it from a smooth 35 mph, and going WOT just didn't feel right ??
Drives fine for my wife. (Light foot)
90K miles 3.6 L RWD
No codes show up with my Accutron reader
Bad fuel pump wouldn't show so fast I don't think ??
fuel filter ??
Clogged Catylist?
ECU ???
Throttle position ??
I will post a Video if it will help.

Press and hold the traction control button for five seconds to turn it off. Still the same?

Excessive oil use is not normal. How many miles are on the car?

It says 90k miles in his post chase. Would it be blow by? Far as the oil loss is concerned?

onlygm, I have a 06 STS V6, 48k. Was burning a quart of oil every 760 miles under Cadillac test. There test is they change the oil, I drove 2000 miles. Under warrenty the piston rings were replaced. Done some reseach and found out the new piston rings are not the same and have a differant part number. 30,000 miles later uses no oil. Unless you rering the engin, buy stock in oil. Danny
