Premium gas

[HolmenTree]

Guess I have to check my tuning on all my 2 strokes now... I just switched over to 100LL avgas. No ethanol.
Running it a little rich with mix too.

Another good point of av gas is the lead in it is a lubricant giving a little extra protection against lean seizure. Only bad point is not so good for your lungs.

My dad used to run avgas gas in his 69 442 4 speed he bought new. I just remember the dual tail pipes always being white.

Do you get Stihl Motomix in US?

 

[sawinredneck]

NOPE!

They only super gas I ever ran was Sunoco 260 in my '59 Poncho if I ran it at the strip and Cam II in my Harley chopper every so often . Some of the guys ran av gas in the hotrods back then .

Now they ran the kart engines on the stuff all time but it was laced with nitro methane and castor oil . Probabley not something the average person would do on a chainsaw .

Something my cousin might do..... Not me...

I remember Sunoco 260. It was dyed blue instead of the usual reddish color.

 

[Al Smith]

Looking back it probabley was a sham .Supposedly it had a custom mix thing built into the pumps which mixed the grade ,It reality knowing what I know now it most likely wasn't what it appeared to be .Between grades 190 and 260 there might have been 7 cents a gallon in 1966 if that .That was back in the days of 27 cents a gallon for regular though . Sun Oil Company I think still makes racing fuels but I haven't seen a gas station locally in years .

 

[MasterBlaster]

I'm going on my second tank of ethanol free reg gas and I swear I seem to get better MPG, and maybe even better engine performance.

 

[Cobleskill]

We still have Sunoco stations here. I think they do still make 260. I remember the selector dial on the pump for the different octanes.

 

[Cobleskill]

Ethanol doesn't have as much energy as gas, so mileage does go down. The whole ethanol deal smelled like crapola from the git-go to me. Subsidies are what keeps it flying.

 

[Al Smith]

You should most likely see at least a slight increase in milage Butch .It takes something like 40 percent more ethanol than straight gas to get the same power .

Long time ago in a different life with a former wife her Olds 442 got about 2 more MPG on a trip using premium .That engine was 10.75 to 1 compression ratio though and spark knocked pretty badly on some lesser grades of regular gas .I had to keep my lead foot out of it depending on the fuel in the tank at the time .Nice factory hot rod ,just fussy about the fuel it drank .

Thats funny, I was talking to one of my younger employees last summer, about fuel pumps, I remember the flip 'switch' and the little glass bulb with the balls floating in it as the gas flowed. Thats only 20 years of fueling cars, I wonder what the pumps will look like in another 20 years? Thats assuming we dont run out of the stuff before then of course.

 

[Cobleskill]

Sunoco really cashed in on those gimmicks, I'll bet.

Algae fuel production could be the future. It sounds good anyway.

Meanwhile, we're all paying higher prices for food, too.

Just seen on the news food is getting ready to take another giant leap in prices. Wages keep going down and prices keep going up. I think mine met in the middle 2 years ago and now I'm on the losing end.

Even though I had my best year last year with wages lower, I put lot more hours in the last 4 months of year to do so.

 

[Stumper]

I run premium simply because I have fewer vapor lock issues in hot weather that way. I have been told that the issue isn't octane but "10% rate" (evaporative volatility). Whatever. I don't care why I just prefer avoiding problems and the premium fuels help. Our last non-ethanol station can't get it anymore so everywhere in town sells adulterated fuel. If I have trouble this summer I'll drive out to the airport and try to buy avgas. Otherwise I'll stick with the convenience of premium pump gas.

 

[CurSedVoyce]

Premium is almost 4.00 a gal here. Might be today. Should see 5.00 per gallon on regular by summer..

 

[rskybiz]

Could not resist sharing this here!

I think that's pretty much the universal feeling .It was I think about two years ago my income was basically cut in half because of a down turn in automotive .

It happened to a lot of people but prices never went down and the government cries like broke dick dogs because they lack tax revenue .:what:

 

[CurSedVoyce]

Airport just cut me off on 100LL. The lady in there today knew me and said NO MORE for you !
I might try the boss man on Wed. or find some racing fuel

 

[woodworkingboy]

Why reason did she give to not sell to you?

 

[NeTree]

I'd love to hear the excuse.

 

[Strikermike]

Try a speed shop for Sunoco 260. I can not see what her problem would be. Unless she thought you were using it on the street. Not paying the road use tax.

 

[CurSedVoyce]

Policy and fear of EPA regs. I guess Sunoco even said something. Probably afraid to lose her job or something.
