Fuel Question

[popknot]

popknot, the only thing I will add to this thread is, high octane fuel doesn't provide a hotter running condition. Higher octane fuels are actually harder to ignite. And that is the reason high compression engines have to use the high octane fuel. Other wise the compression would cause pre-ignition or pinging like we use to hear before computers took over setting the ignition timing in new cars. Lower octane fuels ignite easier then high octane fuel. Sounds counter-productive, but that is how it works. JMHO

Yes. The reason I thought they might run a little hotter was because they are harder to ignite. But guess I was thinking wrong. Do you think since lower octane fuel ignites easier and I have a low compression engine anyway it might actually run better on the lower octane fuel?

Okay, my own personal thinking for what it's worth. I don't think you will see anything different what so ever with either octane fuels. That is other then your wallet. JMHO

Hmm? Is naptha,alcohol and oil all that's in it? May have to reconsider.

Google the MSDS sheet on it.

That's all it is!

If you had fuel injection, you would want to use something that has PEA(polyetheramine) in it which actually is something that does something. You definitely don't want to use SeaFoam in an auto engine that has O2 sensors. In carb'd boat engines, it's kinda pointless to use it.

Funny the mfgr. specifies it's safe for O2 sensors and cat converters, 2 and 4 strokers, diesels and all that written on the can. It's only stocked in every auto parts store of every denomination around here. Has been used for how many years since O2 sensors and combustion computers have been in existence........many. I think that supports the theme: Quality survives the test of time. It has!

LOL...you really think the manufacturer would say anything else? Putting OIL into the gasoline of an engine that has O2 sensors is just stupidity at its best.

Well, through all this a couple of people have mentioned they have used the regular unleaded fuel and never had a fuel related problem. I have to say the same I have used the regular fuel containing ethanol in all my other applications, often stored for long periods of time, and never had any issues. And nobody has chimed in and mentioned that they have had issues with phase separation or know anybody who has. So I think I'll just use the regular fuel and keep it treated with fuel stabilizer, at least through the boating season. And then maybe towards the end of the season if I think it may be in storage for a while I'll start using the ethanol free. Thanks everybody for the input.
