What diesel additive at fill ups?

If you keep your diesel tanks 1/2 full, you will condense 2X more water and are therefore 2X more likely to start your own algae (microbe) farm in your tanks than if you keep them as close to full as possible. You won't burn any more fuel, but you will drive yourself crazy trying to "turn over" your tanks and clean up the mess when you do get some microbial growth started.
 
Frank, if you are following the right protocol, is there any benefit to polishing every few years as an added safeguard? What if the boat is sitting for an extended period time and the fuel use is low. Does polishing for another type of preventative maintenance make sense?
 
Bill,

As long as you are using the right protocol and you keep your tanks full, there is no need for polishing. If you are worried, then once a year, right before a fill up, treat your tanks for full capacity with a shock level of biocide, use Diesel Kleen as you normally do (for full tank quantity) and add the lubricity additive, again for full tank capacity. Finally, add 1/2 gal (I think it is really an 80 oz. jug) to each tank. Then, run the boat as long as possible before refueling. If you follow the above, the only fuel system maintenance you should have would be replacing your fuel filters regularly as you normally do.

One of the neat things about these additives and this method is that you cannot over treat your fuel and everything is 100% soluble in diesel......besides that, it works and is cost effective while protecting your engines and fuel systems.
 
Roger that, thank you

What are your thoughts on SLIPSTREAM marine fuel... The guy that delievers fuel to our dock started using it.. Said the additives are already in it and I don't need to do anything... Thoughts??

Can your fuel distributor furnish you with test data on what his additives are really doing? Also, how are the additives he is using put into the fuel?

In my case, our marina advertises they are a Valvetech dealer yet they have no data on what is really in the Valvetech product they add....It comes in an un-labeled jug......What does it do to cetane? Does it disperse water?, What does it do to lubricity? Does it contain alcohol? But the worst part of it is they only add the Valvetech chemical after they receive a load of fuel. It is poured into the fuel tank by one of the yard guys so it cannot be mixed well.....This is also a guy rides a bike to work because he can't stay sober long enough to keep a driver's license and who isn't allowed to drive the forklift, tractor, golf cart or use the pressure washer. He washes boats, spots for the forklift drivers and handles the Valvetech stuff.

No thanks, I prefer to do it myself with additives I know are correct.

FWIW, I follow Franks fuel maintenance suggestions. My boat is in storage 7 months each winter. I double dose biocide on the last fill. I've went thru the first winter with no problems. I've run 2 months now on the same fuel filters, looking through the Racors things look as clean as when it was parked.
