Hi there,
My toyota rav4 2007 engine is burning oil,estimated 1US quartz every 1600KM.
Common problem with this type of engine and is known by Toyota.
No performance, smoke or other related issues.Can I switch from conventional to synthetic oil? Will this be helpfull?
I have already changed the pcv valve.

Changing to synthetic oil will only reduce oil consumption if oil consumption is due to oil quality dropping.
If problem is blocked piston oil return holes in theory you can clean them with engine flush or pouring diesel or solvent into cylinders and letting it sit. But it may be too late depending one when it started.
The short answer is, don’t. For more info you can read the discussion and watch the videos.
