I changed my oil 6000 miles ago, and reused the old crush washer and my drain plug started leaking. I read on here about the Futomoto Valve and I bought one.
Anyway, the other day I put the valve in and switched to Mobil 1, and it is leaking even faster now! Almost every parking spot in the lot at work has a 4-5" oil spot in it from my car now.
Any suggestions??? It wasnt so bad when i was using normal Castrol, but with Mobil 1, it feels like every drop is costing me 10 cents.
