I didnt read all posts but I
I didnt read all posts but I am sorry to all folks this problem is discussed extensively on Subaru forums, and seems to affect newer cars that use 0w20 light weight oil. My '03 outback never used any oil, not until head gasket started to leak externally which is a chronic problem with 2nd generation ej25 engine. Oil consumption test will prove that piston rings are not sealing the combustion area from oil entering and burning. Dealer will give you runaround overfill the level during oil change as much as 1qt, so the light wont come on until 6k km oil change is due, will say it is normal come back in 1500km. This is a major blow to the brand and lots of used cars on the lot are trade ins with such problem I am sure. Was going to pull the trigger on new Forester XT or another Outback but I am not taking $35k gamble
Driving 2015 car around with bottle of oil in the trunk? This is not normal folks, especially for new '14-'15 models. My other car '13 journey has 80k and I change oil every 13k km oil level stays the same every time. Been swapping fleet cars every 2 years or so until about 120-130k no oil burning on any car.
Oil suppose to stay in the crankcase to lube engine not leak thru the piston rings and burn thru clog the catalytic converter and O2 sensors. If new car burns oil engine wont make it to 50-60k km without either CEL or catalytic converter replacement. I own my outback for 12 years and know outbacks weak spots, older engines used 5w30 oil didnt have consumption problems, they have leaky head gaskets. This at least can be fixed for around 2k, but how you are going to repair an engine that burns oil, swap engine block, pistons? thats expensive, and good luck SOA admitting and paying for it under warranty unless you hire a lawyer.Good Luck.
