Last week i found out my 07 STi was lacking of engine oil from the dipstick indicator so i added about 1 litre of engine oil from the Subaru souvenier bag. Took it down to Melville Subaru, and they said the seal on the oil filter COOLER is not properly fitted. And theres a chance it wont be warranty because i got my exhaust done and someone have messed around with it.

So i went to complained to the Dealer Principal that there's no way that the exhaust people would touched anything near the oil filter cooler or the cooler itself . After few minutes of argument, they finally decided that it is warranty.

O6 / 07 STi OWNERS, Please check your dipstick oil and make sure that the oil is on the FULL line mark! It could be that your car is leaking oil
