I have been using 2 stroke engines of all types for decades. Still do. I mix my own fuel using factory oil and premium fuel.

The consistant decline in gasoline have been causing more and more issues.

The Husky and Stihl premix is expensive. I see this stuff. Rated at 94 octane and no ethanol. $10 less per gallon. Any feedback.

Thanks guys

I use 100% gas with no ethanol and add some Stabil to it. Never had a problem with any of my equipment. I also run 50:1 and only use Stihl oil.

True premium top tier fuel has more and better additives than regular. You probably don't need the high octane in your 2 stroke engine but the additives are good. If I could buy ethanol free premium gasoline, I would add the stabilizer and 2 stroke oil saving lots of money. I can't find convenient ethanol free gasoline so I get the premium with ethanol and use that.

Same here.
It cannot be found in the St. Louis area, it's illegal to sell.

I bring it back from the Lake.

I buy av gas lo lead 100 octane for around $5 a gallon. Mix with Amsoil Sabre at 80:1 and run it in everything. Regional airport is about 10 miles away and 5 gallons last me all season.

I have been buying stihl and husky oil with stabilizer and using non ethanol premium but have still had regular issues.
Looking for a better option. So bought a gal. of this VP 50:1 mix

Go to your local airport and buy 100LL avgas at 100 octane, for considerably less money. You can still blend with oil.

It does have a high lead content.

100LL does not have all the aromatic crap that turns to jelly and ruins carburetors. It is more expensive than the cat piss that they sell at the local gas station, but the savings in repairs and aggravation are well worth it...

ETA: Nah, it doesn't have a high lead content, it is low lead. If you want the high lead content, you need to fly down to Mexico and tank up on their 100/110 avgas (or is it 100/130? It has been a while and I don't remember.). From memory, it is dyed green instead of blue like the 100LL that we have here.

So where does one go at the municipal airport to by
100ll?
I do not recall seeing a storefront at one.

There is either a pump or pumps (often card reader self service) or a gas truck. Generally it is run by a fixed base operator at the airport. What airport? Your invisible friends may be able to look it up online and get you the FBO’s #.

Oh, if it is a self service setup, don’t get hung up when it ask you for the N number. N12345 oughta do the trick, or you could use Nxxxzz where the xs are digits and the zs are letters. This came out of a bad batch of fuel from Chevron where they ended up paying to rebuild a lot of engines. Now if there is a problem they want to know who is affected.

If you happen to live by any racetrack you should be able to buy race fuel there as well.
I can buy 100 and I think 110 Octane fuel there..

Me too!

VP makes great fuel. They are what many of motorcycle racers use, and likely car as well. I mix my own 2 cycle fuel with premium non ethanol gas from a gas station and use Royal Purple synhetic 2 stroke oil to mix it. Works fantastic in my stihl blower, chainsaws, trimmer, and pole saw. Sometimes i even leave it in there for 8 or 9 months and no issues. I do add Stabil in my fuel can just prior to fillng it.

TruFuel canned fuel mix from Lowes is also very good, albeit much more expensive at $5.xx per quart.

If you have marinas with fuel, many have no ethanol. Somestill do though.

100LL and Stihl oil.
No need for stabilizer.
Find a small country airport with self serve pumps.
Racing gas won’t store anywhere near as long and is usually much more expensive.

Where to buy 100LL avgas

Where in SW Illinois? I see several sites listed on Pure Gas.

Thank you guys. Great info. I really appreciate it. I suspect the non E fuel sold locally is tainted somewhat.

Of late I have been mixing my mix (husky XP) and non-e premium and the canned Stihl premix and have had better results.

The old avgas system included 100/130 (green), and 115/145 (purple), and a lower octane 80/87 (red) fuel used primarily in lower compression engines. 80/87 disappeared a long time ago, though many engines certified for it's use can use car fuel (mogas) today.

115/145 was primarily for military applications, used chiefly in high compression and turbocharged/supercharged engines, and also disappeared some time ago. It had no lead limit, but was typically four to six grams of lead per gallon.

100/130 was produced for a long time, and had no lead limit, but used three grams of lead per gallon.

The double rating for the fuel is the octane or anti-knock rating on the fuel, and in aviation fuel uses a rich and lean octane rating. In part, the octane rating is adjusted with tetraethyl lead (TEL) and other additives. Avgas is aromatic. Contrary to popular belief, the octane rating of the fuel does change and does deteriorate over time, though avgas does not form the varnish and system deposits ("gum") common to automotive fuels.

100LL (blue), called 100 "low lead," meets the 100/130 octane rating when shipped from the refinery, but is made with 2 grams of lead per gallon, and uses a toluene additive to meet the final octane rating.

While called "low lead," it's only lower in comparison to the original 100/130 that it was intended to replace. It is less expensive, requires less additive, but 100LL will still damage catalytic converters and foul spark plugs in automotive equipment, especially if not leaned properly. The TEL concentration is necessary for valve protection and lubrication in certain engines, and to meet octane requirements.

It's available at the local airport; some FBO's, or "fixed base operators" are not inclined to sell it for use "outside the fence," some will prefer to sell it with minimal visibility. Most tax and licensing situations do not allow through the fence sales for automotive or other use, but many FBO's will sell it to fill up a personal tank or carrier, and won't necessarily ask about the use. Avgas will typically run about five dollars a gallon, depending on where it's purchased.
