Sea Foam in Vespa GTS125 – [SOLVED]

I have a Vespa GTS125- can I use Sea Foam Motor Treatment? How much do I use (obviously it has a small tank)?

Yes, Sea Foam is safe and effective in a Vespa GTS125. Use 1 oz of Sea Foam per gallon of fuel if you are adding it to every tank, or 2+ oz per gallon for periodic cleaning. I like to add a high concentration (4-8oz per gallon) to a low tank of fuel (1-2 gallons) and run it until almost empty. That lets you take advantage of the high concentration of Sea Foam for the best/most efficient way to clean.

Hope that helps!
