They are motorheads who who don’t give a flying rodent’s posterior that E15 is available at the pumps. Makes no difference to them at all. They don’t use it nor care that it exists.
Where in the heck is that? And if it is 104 octane, it isn’t road fuel, it is race fuel.
Yes and no. E85 race fuel is an estimated 99 octane. That’s why I know it isn’t race E85.
It is likely Sunoco 260 race gasoline, or similar with an octane rating of 104. Not subject to the sales restrictions of road fuel because it is not E15 road fuel.
That sounds like the right number. I pass by on the shared-use trail on the north side of Indian School. I only know it by the cross street. I don’t buy 104 octane. I don’t see any airplanes fueling up there; I assume some motorist is burning it.
In US races, it’s 98% ethanol/2% gasoline. 100% ethanol would be drinkable and that’s illegal in the US. I think some races in other countries allow 100% ethanol, but not here.
100% isn’t drinkable because you have to remove water to get ethanol past 95% (the azeotrope, why Everclear is 190 proof) which leaves behind traces of the drying agents, which are poisonous. It’d also be a waste because it would absorb water from the atmosphere until it reached 95%. And it’d be expensive.
We denature alcohol to make it legally undrinkable, though not actually undrinkable. You can drink enough mouthwash (43 proof) to get drunk without killing yourself; I’ve had less-tasty cocktails.
If there’s ethanol in our gasoline during the summer, will it damage small engines like lawn mowers and chain saws - especially old engines? My lawn mower is a 1967 Lawn Boy 2 cycle.
Good info Troll. Especially, the tip on mouthwash:wink: When I did my senior design project back in college, I researched the impact of E95 on fuel economy, emissions, etc. by converting a vehicle off a dealer lot directly to E95. I assume E95 is still commercially available.
