seafoam users and hydro lock...

[98valk]

so how many who have had HL were using SF at the time? or some other fuel additive such as kerosene, etc.?
could this have actually been the cause of the HL, incompressible and non burning oils?
something to discuss? opinions? are these legit reasons to avoid usage?

 main ingredients of SF
"PALE OILS are light coloured, non-staining naphthenic oils refined from specially selected wax-free crude through the use of severe hydrogenation. This process produces oils of excellent initial colour and colour stability while maintaining their compatibility with most synthetic elastomers. With a flash point of 330 degreee F or more. E10 flash point is around -40 degrees F. Diesel is around 143 degrees F by the way. Have you ever wondered why Seafoam will stall your gasoilne engine unless you rev the piss out of it. Well now you know; the stuff does not want to go BOOM.
Naphtha flash point is a little lower then gasoline. If want to buy Naphtha go buy some Coleman Stove Fuel.
Seafoam has a flash point of 55 degrees F and gasoline is -40 degrees F. That is why when you pour it in a carb the engine wants to die.
The stuff does not want to burn like gasoline and by filling the racor that is exactly you are trying to do. Anybody hydrolocked a motor trying this?"

My hydrolock last week had no additives. Actually drained the old gas out of the tank and all the bowls and added fresh ethanol free gas back in so whatever was left of the old gas was minimum to none. before i put it in the garage i always shut the gas off and let it idle til it dies to empty the carbs. I don't think there is a rhyme or reason they hydrolock.  Many say it starts with the petcock but i don't believe this. Unless gas is flowing down the vacuum line to #6 cylinder. If it does not lock on #6 but another cylinder then you have carb problems that need to be addressed.

I doubt seafoam is the culprit on hydro lock.

I never overdue seafoam or any other chemicals in my gas tank though since I know some guys put a whole small can of seafoam in their gas tank (guessing 12 ounce can?) and personally I think that is too much.    At most I have used 1/2 the can to a full tank of gas. 

I once mistakenly added 2 or so ounces of seafoam to my small lawn mower tiny gas tank and I could not get the darn thing started and I know seafoam was the issue on that since mower ran fine  a few days prior.  sometimes too much is too bad.

I think of seafoam as a gas treatment for ethanol gas.  I never felt it did much to correct issues like Chemtool does.  Second choice would be Techron.  I use a Lucas product now instead of seafoam to treat ethanol gas and like it. 

The other product that is good for routine maintenance is Marvels.  A couple oz in a full tank is all you need.  Its supposed to keep everything from carburetors to the valves cleaner from deposits.  I never had a way to verify but I do throw some in every once in a while

@Chris: would the cleaning effect show up by using one of those cameras to inspect the pistons?

I'm talking about something like:

I would think so, but I would not expect immediate drastic results.  Regular use and periodic checks would be very interesting.

I use seafoam for winter storage. I start using some in the couple of weeks before putting the bike up, and on the last day, I add a little more, and fill with gas. Run the bike into the garage, and put the trickle charger on. Sometimes, the bike ends up being stored 4 to 5 months. I have never had a hydrolock. I use seafoam a couple times in the summer, just to keep stuff clean. I use it in my tractor, and lawnmowers as well.

I think a more logical question would be just the opposite?  Does not using  preservatives have something to do with it? Crap gas that eats and rots the fuel system a reason? Be curious to know if and what product if any they used prior to their first hydroloc?

I'm a fan of Sea Foam...

I'm 68 years old. Been using Seafoam in everything I own with a gas engine for as long as I can remember. Half a can to a tank full on the Valkyrie. I have put 116K miles on the Valkyrie with absolutely no carb problems. I know, like oil and tires, everyone has an opinion. I'm not saying Seafoam is the best but it works for me.
