The Yanmar people at the show said to use FPPF Marine Formula in my fuel. What do you think? Thanks in advance.

brewster, started using fppf, and swiched over to the standene

Got my FPPF from Costa Oil www.costaoil.com The son's owner is a boater and told me he got the FPPF for his boat and then decided to sell it.

Both products work fine.

Some say the FPPF reduces smoke a little more than the Standyne.

I can't tell the difference.

Do any of you guys know anything good or bad about the Fuel-Tek CAL-5 fuel additive? www.fuel-tek.com My biggest concern was the lubricity of the low sulfur fuels and keeping the fuel system clean. I talked to the guy at Fuel-Tek and his explanation was that it is not the sulfur that lubricates, it's the process to remove the sulfur that lessens its lubricity. Along with adding lubricity, it claims to provide stability, remove carbon deposits, increased injector and pump life, promote complete combustion, eliminate smoke / soot, disperse water and stop fungi, bacteria and yeast growth. What interested me was it's concentration (1 oz to 40 gal) A half gallon at $75 will treat 2500 gallons of fuel. Anybody know something good or bad?

Brewster, i have using their products for the past 3 years. Mack Boring pushes their stuff. I like all of their products, especially the Cetane 8 for better performance.
