Oil can be consumed by further skinny oil getting previous piston rings or valve guides and both being burned up or simply flowing by the exhaust system and out of the tailpipe.
Blowby — a course of by which oil, combustion gasses, and unburned gasoline/air combination are pushed previous an engine’s piston rings and into the crankcase — is one other frequent explanation for extra oil consumption sometimes brought on by worn or caught piston rings. That is simply noticed by checking your PCV valve. In case your PCV is oily or clogged, or if a number of smoke comes out whereas the engine is working, chances are high you’ve gotten some blowby.
So, now what?
