Are you sure you actually used that much? Did you check the oil level when you left the dealer? It is highly likely that it was not full when you picked it up. I used 1 full qt during the first couple thousand miles but it seems to have gone away now that I have 7000. Some use in a brand new engine is normal, but not 1.5qts in 400 miles, thats like a qt per tank. I think you would see white smoke in the exhaust at that comsumption rate.dorn22 said:I have about 400 miles on my 2005 GTO. It has used/burned 1-1/2 quarts of synthetic 10-40 oil. Is this normal? Any recommendations?
Don't get too excited. I'd buy into JMVorbeck's theory. I have an 05 and I experienced the same thing you did. At 5,000 miles the synthetic dinosaur juice was down about two quarts. At that point, I had an oil change and refill done at the dealer. In the last 4,000 miles the oil usage has been barely detectable on the dipstick, as it should be.dorn22 said:I have about 400 miles on my 2005 GTO.

Westell, I have no idea about the Gen III but my Gen IV burned some and now it has stopped completely. I have 4000 miles on this oil change so far and the oil is exactly at the full mark where I filled it to 4000 miles ago. I drive the holy hell out of it too.westell said:Gen III engines burn oil, period. Those not consuming oil are in the minority.
I buy 2 - 4qt Mobil 1 bottles. I put 7 in, and 1 in reserve for about 1500-2000 mile refill :seeya:
Isnt it smoking? I had an old honda that didnt use that much oil and it smoked enough to fumigate the neighborhood. You should be leaving a vapor trail behind you as you drive down the road at 2-3qts @ 700 miles. No leaks?huskerGTO said:Oil Burning you say? My Goat drinks the stuff like I drink beer during a Nebraska Cornhusker game...
I've been having the GM "engine consumption test" done on my car for the past 2k miles. This weekend I got sick of waiting around after once again seeing that the oil is below the fill line on the dipstick.
I average about 2-3 quarts every 700 miles. IS THAT SICK OR WHAT?!?! Scheduled an appt to have them look at it. Amazing enough, if you use the words "state" and "lemon" they really do want you to get it in, and my dude actually told me what they'll be doing! (Checking to see if its either an intake valve or an ring that hasn't seated yet. Either way, they know its messed up, and they know I mean business.
Could this be the reason I had crumby dyno results???? hmmmmmmmm
Man, I just dont see how you can move that much oil through the cumbustion chamber without the tell tale blue smoke. You have any dirty neighbors who may be siphoning your Mobil 1?huskerGTO said:No Blue vapor trail reported from my moms and pops who had the courtesy to let me leave them in the dust. They said they saw a big brown streak of smoke. Funny it wasn't blue, but still the same, its my only guess because there are no leaks. At home or in my parking spot at work.
