Looks like my Civic burned or lost 2L of oil in the past 6 months, I think that is excessive. At previous oil change garage mechanics advised me to use 5w30 viscosity oil because 0w30 is too thin. I used 5w30 just to see now that consumption is exaggerated.
I always used high quality oil and replaced it often ( twice per year, around 12000km between drains ). I fear bad/warn piston rings, I must admit that I drove the car at the limit sometimes, maybe more than needed, like revving the engine to the redline. I fear bad rings because enigne always used a bit of oil like 1L per 10000.
Is there a chance for worn piston rings on an gasoline engine which has only 130.000km on it?
However, according to this increasing to a thicker oil might increase oil consumption because of bad rings.
