If you have an 05
I have an 05 Gto just had a new engine put in after it ran out of oil at 8000 miles. The dealer sent me this today..."The accepted rate of oil for engines used in the 2005 GTO is referenced is 0.946 liter(1qt) IN 3200KM (2000 miles)"
This would explain some of where my oil went. I did not check my oil. The dealer change it one month ago at 6700 miles before it blew. it also says.
"This rate only applies to personal use vehicles,under warranty, That are driven in a non-aggressive manner and maintained in accordance with the appropriate maintance schedule. Important: This rate does not apply to vehicles that are driven in an aggressive manner, at high RPM, high speeds. Oil consumption for vechiles driven under these conditions will be more" It says that you must let the car sit at least 15 min before checking the oil and after putting oil in. Now I did this waited that is and my oil leavle did not go up even after 15 min. You have to start the car and let it run for a few and the check the oil again and it will be fine.
I have 2000 miles on my new motor and the car is down 1qt of oil today. I will keep checking it let you know... between the knock sensor and the oil I'm just not sure about the engine....
Anyone else with this oil problem I can't just be the only one?
