This is what I found out too,
This is what I found out too, the oil light is triggered by pressure, not volume of oil, which makes it useless to help with this oil usage problem with the Subaru Forester. The oil light comes on to indicate the oil pressure is critical, which the mechanic told me basically means if you see your oil light, it is already too late. I have had this on-going problem with my car as well, did not realize it was a common issue. Am now facing the replacement of the short block. I appreciate this forum of shared information which has better armed me to negotiate this with the dealer.
