Why is it Im losing so much oil on my Subaru Forester 2006?
Have to top up oil every three weeks. I'm using 5X40 synthetic oil as dealer's
spec yet it disappears quickly as normal. The thing is you cannot find any leak
around or under the engine. Some backyard mech of mine suspected my rings
may have been gone but others said no, because they checked my plugs and
seemed okay, besides the smoke coming out of my exhaust looked
normal...not black. Can anyone shed some lights with my prob? Had almost
five litres of oil already been used for topping within 2 and a half months. thnx.
