My 09 Tahoe has been consuming about a quart every 3,000 miles. It started kicking out smoke when I start it (48,000 miles) so I took it in. They are going to install the deflector and clean the engine. I will be out of warranty very soon so I'm worried about it. Any advice?
ETA: I also have an 09 Silverado but it has an iron block and isn't consuming any oil. Is there anyone with oil consumption that has an iron block?
