Hello everyone. This is my first post. I found this website looking for advise on my new 2014 silverado I purchased in August. My truck has the 5.3 engine and my issue is excessive oil consumption. My truck calls for 0-20 oil and it's using about a quart per 900 miles. The dealer said this is normal and the engine is still breaking in. I have 4200 miles on the truck and this just seems excessive to me. It just drive it for commuting I haven't towed at all and haven't even hauled a heady load in the bed yet. Any advise would be appreciated. I'm sick over this I paid $35000 for this truck and I saved for years trying to afford a new truck. Thank you
