Is anyone using gas additives when filling up? These products claim they neutralize the bad effects of the 10% ethanol that is added to gas. Any merit to these claims or is it just a marketing hype?

Re: ethanol gas treatment additive

That depends on what the treatment contains and what it "specifically" aims to treat. Lets set the record straight. People are blaming all sorts of things on ethanol when in fact ethanol has nothing to do with the problem. Anytime ethanol blended fuel is introduced to an area some old engines (pre-1987) or vehicles/boats with neglected fuel systems (neglected as it dirty, full of water, etc) may experience clogged filters, plugged up carbs, and as a result poor operation. Ethanol is an excellent cleaning agent and will do a good job of cleaning the fuel system so be thankful for that. The down side is the filter and carb clogging but you would have had that problem in a short while anyway. The issue is that people tend to run there engines knowing they have an issue. Clogged carbs means lean fuel mixture. Lean fuel mixture means lack of lubrication. Both conditions can cause an engine to burn a piston, score the cylinder walls and therefore result in a rebuild. If your engine acts up, whether or not you use E10, fix it. There are reports coming out of the east coast where for some reason they seem to be seeing more plastic and rubber part failures than elsewhere. Ethanol can create failure of fiberglass (not plastic) fuel tanks. Ethanol attacks the adhesives used in tank manufacture and turns this stuff to a glob of goop which can also result in fuel leaks. There is no fix for this. We've been using E10 in the midwest since 1997 and there are no issues except as pointed out. If you have an older engine, clean the fuel system, replace fuel system hoses, fuel pump diaghrams, and carb kits and gaskets with current E10 tolerant replacements and go boating. Chances are your engine needed this even before E10 came on the scene.

snake oil, once your system is use to enthanol, not needed. may have to clean the carbs, as the alcohol, loosen crud in system.

Re: ethanol gas treatment additive

Silvertip is right on the money. Most of the problems I've help diagnose where from neglected or inadequately protected fuel systems. Most I know that took the proper precautions limited their problems to a couple of abrupt fuel filter changes.

About this time of the year my fuel starts get cloudy and water start showing up in drains in my Racor. Nothing serous, but I have to keep and eye on the Racor and drain it from time to time.

Last fall I stumbled into a case of Startron at a price I couldn?t resist. Out of curiosity I added a bottle of Starton to the tank to see what would happen. Well it cleared the fuel up and water no longer accumulated in the Racor. I?ll give it that. Would I run out and buy Starton at full price to resolve what was a non-issue to begin with, doubtful.

The best approach I've found so far is to top off the tank before each outting in an effort to keep fresh fuel into the mix.

As a 10 plus year user of E10, like others I have no issues.
