Ah the seafoam, required ever 10k miles on a B headed car. Never was a huge fan of basically lighting the inside of your crankcase on fire (which is what it pretty much does) but I've seen too many ****tily running cars fixed by it. Also have seen more than one dip**** ruin an engine with it but that was their own damn fault.
2000 Mustang GT Steeda build #48. Bolt ons, suspension, Novi 2000.
Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
