Seafoam
Seafoam really isn't much different from any other "mechanic in a can" fixes out there, and a properly tuned motor should really never need anything like that. My '93 150 with that 300ci motor had regular tune-ups by a fleet mechanic and often sat months without being used. Currently has 92k on it and the motor couldn't run any better. The only possible quirk is sometimes it has a slight hesitation right off idle, but it only occasionally happens and doesn't get in the way of driving.

I pulled the filter to inspect it after some ones else had problems with there filter after the treatment - The black particles are normal - what I didn't like was the filmy like stuff- Like a very thin film - chunks of like plastic - looked pieces of a plastic sandwich bag, where did that come from? I'm think it's some kind of film on the inside of the tank that Seafoam can't fully break down. I had prolly 180,000 on my truck, maybe it's just something that developed over time.

I think the best procedure is to replace the fuel filter after Seafoam fuel treatment, when I bought my used '92 in May first thing I did was get an oil and fuel filter change, and I'll get fuel filter done again when I get the oil done soon, I figure I'll have all the crud well and truly flushed by then, and the new filter won't be getting clogged.
