Hi, was wondering if other 3.6 engines are using oil,as mine does just around 3k a quart. Dealer says its normal,but i think its ridiculous to add two quarts between changes.Have 39 k on it and noticed the loss starting around 30k. My verano did the same and the dealer did nothing. Never used a drop with the 2.4. untill around 60k.now it also uses around a quart every 3k. What gives, GM claims they wont do anything unless its around 2k and under. What a joke.
