as humorous as it may seem to you, I dont hardly find it amusing at all... when you are refuting what I stated as fact without any knowledge of the product yourself, other than rumor....This is very funny, you tell him to use seafoam which contains 89% ethanol as its base, then tell him not to use ethanol blended gas because it will harm his engine.This is an ole wives tale that will not die, any EFI motor will not be harmed by ethanol fuel in any way except when you add water to your gas tank which is a maintenance problem not an ethanol problem. To OP first get a svc manual for your motor so you know what your ECM fault codes are and how to access them from your ECM. This will eliminate all this fifty year old advice your getting here about how to tell if your plugs, pump etc are working. This is 2014, your ECM will tell you when any of those components are not functioning. Second make sure you check that your oil pump is bled of all air, it supplies oil to crank bearings in addition to cylinder piston lube, your svc manual (not a Chilton, a real manual from your manfctr) will tell you how to bleed the oil pump and the fuel rail of air. And never run an EFI motor dry of fuel, it is not in any way similar to an old carb'ed motor, beware of out dated advice it can cost you big money...
see the seafoam MSDS sheet for the facts.
and I did not say ethanol gas would harm the engine, but what I did say exactly was, "if its in a marine application I would recommend using nothing except ethanol free gas in it... forever. as that will prevent any future fuel system troubles."
but i will say this now for a better understanding...
when ethanol-free gas evaporates, it leaves no sticky residue... but when ethanol gas ages and evaporates, it will leave a sticky residue that clogs filters, plug up jets and injectors, and can generally gum up anything in contact with it....
when ethanol gas sets in a container for 6 months, you will see a black gum in the bottom of the container that has seperated from the fuel....its caused from the "ethanol" part of the gas.
the ethanol gas begins to deteriorate many time quicker than ethanol-free gas. this gum is a result of it
let ethanol-free gas set in a container next to it and you will NEVER see the black gum that has seperated from the fuel... because ethanol-free gas doenst have it in there to begin with.
there is such a thing as disagreeing, and thats fine and normal, but when suggesting someone else is giving out conflicting information, it would be well to have the proper facts in order, so then we can all learn something from it
what I stated is a fact, not an opinion.
