ive been keeping a close eye on my oil level for a few weeks now and it has been on the low side even though i have added oil each time. i have to add about 1/2 qt every 4 or 5 days (regular driving, haven't kept track of miles yet) but it continues to lose oil somewhere. I have looked all around it for an visible leaks but don't see any.
I had it in a shop a couple of months ago for other stuff and they said it will need a new head gasket soon but the oil looks and smells fine...
has anyone had this issue before on their truck?

 

Any blue or black smoke out the tailpipe? What does the coolant look like?

What engine and miles?

 

no blue or black smoke, coolants fine (keeping a close eye on that too) v6 (3.0L)

 

V(3vz-e)

 

Have you taken a look at the spark plugs? Seems you have to be burning it internally or dripping/leaking someplace externally where it is hitting something hot and burning off while driving thus creating no drips.

Give the engine a good degreasing, if needed, which may help to spot fresh oil.

 

i havent checked them yet but planning on it tomorrow
