Removing ethanol from gas

[543_Dallas]

I use the tru fuel in the weed wacker. The quart lasts almost all season so it's not a bad deal.

The local Walmart sells ethanol free at the pump. The Kohler engine on my Miller hates ethanol. It's harder to get started and will occasionally die when it's been idling and the governor bumps up the engine speed. No issues at all with ethanol free gas.

It takes more ethanol to make the same power as gasoline. The ethanol stuff may be cheaper but a lot of people say their fuel milage goes up when they get the good stuff. I don't know. I've only ran ethanol gas in my gas truck and the other one burns diesel.

Ethanol should be used for drinking not motoring!

Want GOOD GAS with high octane? Aviation fuel, or AVGAS. Better than racing fuel!

Best thing in the world for old cars and any generator or 4 cycle engine that doesn't get run much.

Plus you just can't beat the smell of burnt AvGas coming out of the Model A tailpipe.

Is boat gas anything special? I'm close the Buckeye Lake. That gas website shows a station that has ethanol free. 5 gallons would last me two years, unless I ride my bike more than usual.

Mud , I use the Stabil Marine additive when I pull up to the fuel dock , it's more $ but they say it's " Supposed " to be a better grade . Been using it close to 5 years now in 300 Yamaha & no issues so far . 73 , Leo

Aviation gasoline has ALWAYS had a different formulation than automobile fuel.

The octane rating DOESN'T transfer 1:1.

Sure. Things will run on it. But it has drawbacks long-term.

Discussions on NORIA or BITOG are a start.

Back in 1976 I filled a 5,300-lb V8-440 Chrysler Town & Country with 115/145 octane aviation fuel. Made a 110-mile run from North Dallas to Lake Tyler in just over an hour (55-mph speed limit). I kept the cruise at just above 120-mph after any decelerations, etc.

Leaving town passed a guy doing 60 or so in a brand-new ‘77 Corvette just as I was nearing the 3rd Gear WOT shift point. He floored it, so I stayed on it as he wasn’t about to get blown away by Mommas station wagon . . . but he was. I hit that 92-mph mark and we started accelerating all over again. (Buh-bye hairy-chest disco king)

Made the return run a few days later with six guys in that wagon. Had three brand-new V8-460 Grand Marquis owners been gambling out at Shreveport. Kept irritating me by passing then slowing. Wheezing Fords. Finally, just settled in to a 96-mph cruise and they faded from sight.

Dialed the advance mechanisms back and re-set the part-throttle back to stock. Plugs were “clean” but toasted. Slap in a new set, and back to Regular.

I ran that old beast harder than that trailer towing. WOT for more than 20-minutes climbing La Veta Pass. Etc. Plugs looked like they should.

Do some investigation.

Hey Leo Just bought a 2019 tracker 195 tournament edition with a 150 merc. The mechanic told me to use only mercury additives...

so what arte the drawbacks? The model A has 5.1 compression so octane doesn't matter, AvGas has a shelf life of about 6 months (by the FAA) this means for non aviation it will last several years without "Going Bad' like pump gas.

Any car that gets driven like you said would eat spakpliugs. Remember you were back in the 70's and titanium tip plugs were things that you only dreamed about. Normal plugs lasted about 10K before you needed to take them out and sandblast the deposits off of them (low voltage ignition + Lead = deposits).

AvGas works great for 4 stroke engines you do not use regulariiy. I fill my generator, never worry about draining it and it cranks on 1 pull when tested for hurricane season.

Plus AvGas doesn't smell if you get it on your hands.

 

[357magnum]

Bobby , They never told me that ? But then again Dealership it came from guy was kind of an Arse hole ! Only thing I was told it has to be serviced/winterized by a Certified Yamaha mechanic until the warrantee runs out & I think this is the last year .

I think you missed what I wrote. I worked that engine 10X as hard and didn’t ruin the plugs. Av Gas was fun, but not ideal for cars. It’s the wrong operating environment for the formulation.

20-minutes at WOT with a 14k combined gross rig at 9,000 feet (do the HP reduction for altitude) is a huge difference from only a few minutes accel time with a car varying between 5-6k at a few hundred above sea level.

And that car had been fitted with Chrysler’s transistorized ignition.

It’s the lighter duty work that cooked them.

I haven’t said no one should use it. But you’ll have to fill out the tax forms to do so, and — as it’s simply not ideal as a one to one swap — the question is why.

With others, I’d just use recommended additives.

The other part you missed is that THE QUALITY of today’s gasoline is terrible versus what we had 45-years ago. This has nothing to do with lead or no lead.

The extremely tight controls on these modern marvel engines are why the quality doesn’t matter as much. Good luck running an older engine without a complete redesign. Daily hard service.

Experience with available fuel is where it’s at. Correct storage and additive mixture. Supply of both.

Av-Gas will be highly restricted in the event of a problem.

If that problem presents you with reliability issues (learning curve) using conventional gas, nows the time to get that out of the way.

I foregot to say thati ts easier to get when you have your pilot certificate.

Home depot sell 4 cycle fuel in quarts.

If you want a good clean burning fuel that will help your engine last a long time,
LNG, Propane, and CNG. My dad had an International Harvester that ran on propane and we never even had to take the valve covers off. Changing the engine oil every 5000 miles(75 Hours) seemed like a waste because the oil looked as good as the day we put it in. We changed the spark plugs once in five years, and I doubt it needed it then. Looked just like this one.

My grandfather has 300. It's had a hard life and is more of a natural rust color.

Ours perished after an accidental shed fire caused by welding sparks. I'm so glad I was over 5,000 miles away when that happened! My dumb ass brother could not blame me for it. Thinking back on it, it may not have been so accidental.
