09 Civic R18 engine with around 41K miles on it. Never noticed any oil consumption before, but today I checked and the dipstick was half way down. Only 2500 miles since last oil change (Dec 2014) with Subaru 0w20 (Idemitsu made) and it took about 1/4 quart to bring it back to full.
We did have an extended winter for basically the last 4 months with daily cold starts. I'm thinking that the valve seals or possibly piston rings might be leaking oil into the cylinders during cold starts due to shrinkage in below zero temps?
This engine isn't known for burning oil at all especially with such low mileage and proper maintenance. There are no oil leaks anywhere, any ideas?
