oil consumption

so i have a 2009 tacoma with 4cyl and 5spd it seems to go through oil a qt. every 2 weeks replaced the pcv valve any other thought i am running 5w20 high mileage oil

 

Any sign of a leak or oil smoke from the exhaust?

Watch the exhaust when started after sitting overnight. Does it smoke a puff? Have someone follow you and watch for smoking when you shift gears. If it does it seems you may have worn valve seals and guides.

 

What is the mileage?
Service history?

Could be piston rings, valve seals, gasket seepage, leaks........

 

Try a 5W30 HM oil.

 

A quart every 2 weeks doesn't tell us much. A quart every 3000 miles or more is not a problem. A quart every 1000 miles or less is.
