Additive Treatment for Ethanol gasoline
I was told that with the amount of ethanol being put into gasoline ranging from 10-25% regardless what the sticker at the pump says...the additives are not only recommended but almost required to prevent start/run problems in marine applications.....because you don't tend to empty your boat tanks as quickly as automotive, in theory you don't need in your truck. I was told Seafoam was the best additive to use, anyone else run into issues or have a better recommended product? Also was told Kwik Fill doesn't use ethanol additives, anyone corrobate that myth?

Use an inline water separating filter.

I've been getting all my gas from CoFo(Citgo) and haven't had a problem... Man I hope I didn't just jinx myself. Had gas sit all winter and no problem, same with the stuff we've gotten this year, although it isn't doing much sitting. Still not water problems.

"because you don't tend to empty your boat tanks as quickly as automotive" I haven't found that to be true. 
If it has fins and gills, I'm there.

I use something in a blue bottle. It was like $12 and works great. blue star or something...I dunno. I got it at the marine shop by the docks where the EJ moors.
I run a little jet boat and the difference was HUGE once I started putting in the additive. I saw much faster revving, better high end speed and horse power and easier starting. I only burn through a couple tanks a year, so moisture accumulation is definately a concern for me. I highly recommend the additive to anyone that is running a boat and isnt burning a tank every week or two through it.

Seafoam works well. One can in my 20 gallon tank works wonders for my 95 Merc 150 EFI. I also use Marine Stabil evey time I fill up. Prevention can cure a lot of problems down the road since we live in the land of limited fishing time here in the north country. Unless your unemployed or retired, then you can go till you check says no. Suck a fat one umemployed folks. Retired get a pass with me, they earned their stripes. I have no idea what the above post means to SOME people.

Sta-Bil makes a new marine formula too and I believe its a little cheaper than sea foam.

Been using seafoam with an inline H20 filter that seems to work for me. The volvo engines do not like ethanol. I run the high test 93 as well.

Well, I don't know how to say it, but nothing is going to remove ethanol from gas, not Stabil, not Seafoam, not anything. They will help keep gas fresh and help reduce the water in gas. Ethanol is hygroscopic, meaning it has a tendancy to absorb water. So in short, I water Seperator is a must for marine engines today. Also, where possible, it is a good Idea to unplug your fuel line from your motor and run your motor at idle until it is out of fuel to keep from gumming up, especially if it has long periods of time in between use. Fuel injectors and Carbs can become gummed up fairly easy, especially on new engines that have strict emissions. For my motors, I use Stabil at every fill up (Since gas only has a shelf life of 14 days), and I also use the Johnson/Evinrude/Omc fuel conditioner for 2 or 4 cylces. Mikelak Marine turned me on to this, it is not cheap, but works excellent. It is around 8 bucks for a 16oz bottle. For my kicker, I unplug the fuel line and run it at idle until it is out of fuel. It is a 2009 and I have had to clean the carb out twice since at the beginning of the season, I was leaving the fuel line plugged in.

thanks for the inputs, (except you Young Guru)......does anyone know that Kwik Fill or other major supplier does NOT use ethanol? Also, not to badmouth another, but I've heard Sheetz ethanol % ranges into the 20% range, typically.

The reason ethanol is hydrophillic is that it has an OH group on the molecule, making it an alcohol. Any two molecules with OH groups have an attractive force called Hydrogen bonding. That is why water (HOH) gets pulled into the fuel. These fuel stabilizers offer a different kind of molecule to help use up those available OH groups, thus reducing the amount of water that can be absorbed. They arent going to do anything to remove the water that is already absorbed into the gas, which reduces your caloric density, resulting in crappy engine performance.
having more ethanol in the gas is not really an issue if you add enough of the fuel stabilizers, just make sure you get ones that are Marine rated or Ethanol rated, b/c if they aren't (like regular stabil) they just keep the heavier organic molecules from plating out of the gas. It is the heavier molecules that plate out and gum up the engine, so regular Stabil won't do much, if anything, to help reduce the effects of ethanol in your gas.

Currently in the US it is only 10% ethanol, there is a push for 15% from the ethanol producers. Most boat motor manu. will not honor warranties w/ anything above 15%. ORIGINAL: tmccart388
