| Re: Oil Consumption
In the recent past I recall GM's definition of excessive oil comsumption is 2 qts or more in 2000 miles. My guess the dealer can't get reimbursed unless there is documentation oil comsumption is excessive per GM's definition. This is probably GM's way of drawing a line in the sand to say we won't pay for repairs unless comsumption is greater than a certain amount BUT to say it's normal is not correct in my opinion.
If "loose tolerances" were the culprit that would imply a much higher percentage of the popluation would be oil burners. Like the other posters none of my GM vehicle come close to using even a qt/5000 miles. I'm still using 5W-30 in the 95 S10 @111K but I know that anything mechanical is built to a tolerance. If those tolerances line up wrong excessive clearance can and do happen.
Has it gotten worse with mileage/time? At 3/4 qt/1000 miles you are getting close, assuming the 2qt/2000 is still the magic number. I'd ask the dealer to see the actual GM document stating what he told you. |
