Seafoam: Yes? No? When? Why?

[Motogeezer1949_imp]

I use Star Tron and Sta-Bil when my bikes are going to sit a while. Thats about it, with the exception that I use ethanol free fuel almost exclusively.

I have used sea foam in everything that has an engine,with today's funky fuel . Great stuff use in in every tank ,every time I get fuel

Get rid of ethanol.. Would we need any of these additives..?

[the Ferret]

Gas was deteriorating and leaving varnish in float bowls and jets long before ethanol was even thought of.

Short answer YES imo

I use it in bikes that sit for long periods and sometimes in my Vulcan. Haven't bothered using on CB. The Vulcan builds carbon so it needs it.

Many of the additives mentioned address ethanol issues on their packaging ,or is that just marketing?

Cars and bikes that sit unused for a long winter and not stored in a climate controlled garage benefit from using Stabil mixed w/ a couple ounces of 2 stroke oil in the gas tank. This cocktail mix protects against fuel breakdown plus moisture and condensation in the exhaust and fuel system.

I always fog stored engines, aluminum oxide = sandpaper. I use stabil marine since the introduction of ethanol. So what does seafoam do? Or can I use Marvel, It smells better..

I have used Star Tron in my Moto Guzzi for over 6 years. When I purchased the bike the dealer said to use regular grade gas even though Guzzi recommended premium. I followed his advise for the 1st year until I discovered Star Tron. I now use premium grade and put one ounce of Star Tron in the tank with each fill up. Star Tron says that it keeps ethanol and water in suspension and stops phase separation. Have no way of knowing if that is true. However, my Guzzi has a plastic tank that does not like ethanol. Guzzi replaced a bunch of tanks under warranty and a couple of yeas ago switch to a steel tank. I have had no issues with my plastic tank and it is now 7 years old.

The reason the Guzzi dealer recommend regular was it cycles through the under ground storage tanks faster than premium. The longer gas sits, whether in the ground on in the bike, the greater the chance for water contamination.

My dealer recommended regular vs. premium. On road trips I choose premium and now I use just premium for the anti-knock. Regular is just not that good for it. For my Griso.
