Who use Petro Can 94 w/10% ethanol?
...does 10% ethanol affect your brass and rubber carb parts?
just read that in Jan. 2017 all fuels will be required to use at
least 5 % ethanol.
I use petrocan 94 with 10% ethanol. I run it cause I have iron heads with 10:1 compression. I don't nessecarily NEED it. I'm sure my car would run fine on 91. I just prefer the extra few octane points. Little extra detonation prevention.
No problems whatsoever. I have no buildup or problems with it in the carb (my carb has other problems however). No problems with it in my lines. My filters. My hoses. Etc etc.
Any of those "myths" about Ethanol gas are just that. Myths. I think some may have come from the methanol world. I worked with methanol race cars (sprint cars mainly). And yes. Methanol eats hoses. And foam in tanks. It will eat through the bladder. It will eat o rings and whatever else. You do have to drain your race car at the end of the night. But Ethanol is not Methanol. I've yet to have ANY of those problems. At all. And I've been running it in every fill up for three years.
Here's what really happens with Ethanol. You get less mileage. Ethanol has 33% less energy than gasoline. Which means to get the same power, you burn 33% more. BUT with that comes a TON of octane. E85 has a 100-105 octane rating. If you buy from a direct supplier (like most race guys do) it will come at a guaranteed octane rating. How much would race gas with 100-105 octane rating cost? Add on top of that the extra cooling of ethanol. Cooler intake charge, with higher octane rating, means incredible knock reduction. There are guys playing with 14:1 (and higher) street engines on E85 right now. That's incredible to me.
