2011 GMC Sierra 1500 - Oil loss

Truck is losing oil some where . No oil leaks and truck does not smoke . And the oil engine light did not come on .

How much oil does it use in miles per quart? The catalytic converters reduce visible spike.

I think you meant visible smoke?

^This +1. A quart between oil changes isn’t a big deal for a 9 year old truck. OTOH, if you’re adding a quart a week…

Yes, smoke, I guess my proof reading skills failed, again.
