A big shout out for Sea Foam

[Tom Galloway]

White can with red letters - this is a fuel additive that really works - usually the most expensive on the shelf but if your car needs more "snap" the second can will do it

[digger]

works to do what exactly?

[e30davie]

Gives more "snap" apparently, whatever that is.

[Frosty352i]

what about the crackle and pop? or is just snap better?

[DesertBMW]

Sea Foam is a scam
