Checked my oil today for the first time since giving it a change last week. Had just bought the truck a couple days prior to giving it a change. It's down halfway already, haven't noticed a lot of smoke so I'm not sure if it's burning... but also haven't noticed any spots at all in my driveway, at that rate I'd surely see something right?

Only other thing I can think of is that it's collecting on the engine or underside of the truck. Underside is already pretty caked with oil/dirt but I figured it was just from never being cleaned.

Hopefully it's an easy fix because I do not have the money or knowledge right now to replace the head or anything inside the engine.
