I'd think that running 93 just for the knock insurance would be nice. Then again I "tuned" my NA for 91 by bumping the timing 4 points so I have to back it off in the summer

I'm just speculating that "E-85 is better than 91/93 from a detonation standpoint" might be their logic for not having a 91/93 pump. If you were to roll in on fumes in something requiring premium that has a fuel system capable of handling it, it wouldn't be the end of the world.

You're going to need more than just "something recent" with a fuel system that isn't hurt by ethonal to run E-85. Most cars won't be able to handle 85% ethanol without a re-tune and possibly bigger injectors at minimum. Cars that are built for E85 have multiple engine maps that can adapt to the lower powered fuel. Most vehicles out there aren't going to run properly at all. You would be better off putting midgrade in and letting the computer adapt to that than putting E85 in. The former just involves pulling timing, the later is a completely different air/fuel map. bull3964 fucked around with this message at 21:12 on Sep 4, 2014 |

I also used to live in Arizona and yeah, the floods are surprising. One thing they warn you about is being out in the desert when there's a thunderstorm, even if it's not in your area. You'll be standing in the sun and see a storm off in the distance, and figure you're okay, and then half an hour later BAM a flood comes out of nowhere and washes you into a canyon and you drown. What's happened is the rain falling in the distance wasn't able to soak into the baked, hard-dried earth, so it just ran whichever way was downhill and ended up at your location in a big mass all of a sudden. The desert is a strange place.

The state of Tennessee seems to have some sort of weird hardon for non-ethanol gasoline. When I lived in middle-of-nowhere NC ten miles from the nearest little hick town (which was in Tennessee) the gas station there made a big point of promoting their gas had no ethanol, and it was significantly cheaper than ordinary e-10 in NC. Since I was always driving around out of boredom, I would fill up there, though it really made no perceptible difference. Recently I visited the hellhole known as Knoxville, TN, and was surprised to see that Conoco stations there charge a small premium over other stations, but later noticed they too make a point of the fact that they sell non-ethanol gasoline. The Conocos always had a lot of cars there filling up, so someone must care. I guess it would be nice to have the option of non-ethanol gas for use in stuff like outdoor power equipment. If I was unfortunate enough to have to live in that god-forsaken shithole corpse of a city, I'd probably drop the extra $3 a tank on real gasoline, but thank christ I stay the gently caress away from there. Knoxville is tied with Dillon, SC as the shittiest place I've ever been.

If there are older vehicles there, that's probably a big part of it. Carbs prior to sometime in the 90s have a higher zinc content, which ethanol erodes...also a lot of the rubber lines and older gaskets and diaphragms, etc. All the current replacement stuff will work, but if you haven't replaced all of it, it'll erode poo poo and leave deposits all over the place.

# ? Sep 5, 2014 07:07 |

It's the water the ethanol carries (up to .5 percent by volume, a few ounces possible per fillup) that forms zinc oxide, but you're otherwise correct. And the ethanol itself can mess with rubbers.

That would make sense in the first case, I was driving a fuel-injected Volvo 240 at the time (~2009) and the LH-2.4 injection was presumably designed for pure gasoline and didn't care, but there were a ton of old country-boy trucks with carbs driving around. This was Johnson County, TN, best known for that song about moonshining called Copperhead Road, from the 80s. Knoxville is also full of redneck shitmobiles, so it's probably a mix of them and people like me who would pay the extra money for real gas as well.

It really depends on your car. An acquaintance ran his unmodified Volvo 740 (non-turbo) on about 40% E85 (34% ethanol) for two years with no problems. Changed his injectors to Bosch Orange (310cc/min), and with no further changes he fills it with straight E85 and has done so for a couple of years.

With an older car and an injector swap, I can see that working, as long as you consistently use the same fuel. The kit I linked basically causes the injectors to fire twice (the second time being a shorter pulse) instead of once every time the ECU commands them to fire - the reasoning behind that logic is the ECU will realize "poo poo's rich, better cut back" if you're running on actual gasoline, and run normal if it's on E-85. I know GM's Ecotec ECUs are rather picky and tend to toss a CEL if you do so much as add a header + catback.. or even fart near the MAF.

Usually charge a bit more for it but I always pay the extra for the older cars that don't get driven as often. But yes otherwise Knoxville, especially downtown is loving terrible.

Geirskogul posted:And after a short bit of time that clogs the gently caress out of cats in cars. Our office had a Navajo which we used primarily for shuttling prisoners around. That plane always had an issue with the outboard tanks picking up water, as the plane was not stored in a hangar. Any time he had to drain those tanks our pilot would save the contaminated fuel, run it through a water separator then we'd dump it into whatever vehicles were nearby - usually the vans. Excess fuel made it into other things as well. tip : mowers and weedwhackers run sweet on 100LL. We lost the plane several years ago, ditched in the sea while on approach with a full load of pax. (No fatalities, only minor injuries.) Unofficial cause : loss of power in both engines due to contaminated fuel.
