E0 or Ethanol-Free Gasoline superior for pre-2001 vehicles as most automobiles produced before 2001 were not designed to be used with ethanol based fuel mixes. Save gas & money by using Ethanol Free gasoline if you can find some nearby using the Pure-Gas smartphone apps for IOS or Android or the Website, link in the posting :)
Most small carburetor engines are damaged by ethanol so lawn & garden, scooter, motorcycle & other power sports engines tend to be more reliable & get better fuel economy when they use ethanol free gasoline or E0.
Ethanol great in Flex-Fuel vehicles where the fuel system gaskets, tanks, seals & other parts are stainless steel or corrosion resistant & not damaged by water or ethanol at any concentrations up to 85% ethanol content in E85 fuels.
Saving Fuel Improves Profits by Lowering Operating Costs
If a trucking, airline or other transportation system able to reduce fuel consumption by 3-5% that would improve profitability & they would immediately adopt any feasible technologies to enable such fuel savings that also reduce emissions. Ethanol added to common gasoline in the USA called E10 widely available at most gas stations reduces your vehicles fuel economy by 3-4%, while E15 reduces fuel economy by 4-5% because of the higher ethanol content. Ethanol not even legal to use in boat engine fuel because of how ethanol attracts water from the air & can cause corrosion of the fueling system, fuel tank, injectors, head of the engine, valves, pistons, cylinder walls & lead to reliability problems & reduce engine life.
If you want to find Ethanol Free Unleaded Gasoline
Pure-Gas also has an app for IOS & Android smartphones to find E-Free or E0 Ethanol Free gasoline on the go & it works great on both platforms in my testing. I usually look up the station on the Pure-Gas app then copy the address into Apple Maps or Google Maps since those are more polished navigation apps if I am going to an unfamiliar ethanol-free gasoline station.
Locally I go to The Grange in Issaquah to fill my 2.5 gallon or 10 liter HDPE safety sealed button controlled tube dispensing gasoline can. I add 1oz of red colored Sta-Bil fuel stabilizer to the can before filling it with fresh ethanol free gasoline. This makes the fuel stability increases from 2 months to over 2 years.
Ignore If Your Regularly Refuel With E10
E10 fine if you are adding gasoline to your car or truck or ICE vehicle every 1 month or more. If you have some old gasoline in the tank, like 2-4 gallons, fill the tank with fresh gasoline to help solubilize some of th gum polymers that have formed whitish threads in old gasoline.
In extreme cases you can remove & filter the polymer threads out of the fuel by carefully filtering the gasoline from one can to another, with a coffee filter or nylon stockings or fabric or any filtering media, placed into a funner in the receiving can, such that as you pour the old gasoline into the funnel the filter will capture the polymers & gums that are prone to jamming fuel injectors & drying into varnish like lacquer's in the carburetor jet or bowl or float or jamming the fuel injector nozzles or fuel pump or fuel filter.
E85 ok in Flex-Fuel, but 30-40% lower fuel economy results
Most Flex-Fuel vehicles sold in the USA like the Chevy HHR are gas hogs that get terrible fuel economy. I consider anything lower than 30 MPG abysmal fuel economy when a standard Toyota Prius can achieve 45-60 MPG using regular unleaded fuel without any special driving techniques, and have sold more than 15 million units worldwide & are widely available as used cars with excellent reliability & long life, many able to go 350-700K miles without any major or expensive repairs.
Excellent fuel economy + high reliability why Uber, Lift & Taxicab companies use Toyota Prius vehicles, they give some of the lowest total cost of operation of any vehicle available, sorta the way the Boeing 787 uses half the fuel of a comparable older passenger airliner, like the 767.
Blended Wing Aircraft 27% lower fuel consumption than Boeing 787
Future Boeing airplane using blended wing technology will be able to get 27% better fuel economy than the 787, since the "Tube with Wings" shape not nearly as aero-efficient as a blended wing aircraft.
The problem with blended wing aircraft comes down to the need for active computer controlling the flaps hundreds of times per second which requires complicated costly low glitch highly optimized redundant electronic control fly-by-wire technology originally designed for the B2 Spirit & other military aircraft where control system cost was not profit sensitive or cost naive.
X48B by Northrup Grumman shows the benefits of a carbon-tape layup robot blended wing body aircraft in terms of superlative economy but also greater range & performance.
Airline Fuel
Jet A fuel used by airlines does not contain ethanol. Its highly refined version of kerosine that has excellent low temperature performance & does not expand or contract as much due to the changing pressures that aircraft experiences while ascending or descending in pressure cycles in Earth Atmosphere, many passenger aircraft doing this multiple times per day.
Another reasons the tube with wings platform common for passenger airplanes, its easier to certify such tubes with windows as flight worthy for the FAA which requires extensive testing of anything going on an airplane, such that a ROTAX aircraft engines like the UL912S much more expensive than a similar ROTAX engine for on-road or off-road non-aircraft applications. Even batteries for aircraft cost a lot more than identical batteries used on-road applications.
Small Engines or Carburetor Engines
Our 2013 Honda PCX150 scooter for example only holds about 1.1 gallons of fuel max. It gets around 100 MPG so range is about 100 miles, but we only have 5400 ish miles total ODO on the unit, so I only re-fuel with Sta-Bil stabilized ethanol free gasoline to prevent fuel system problems.
I fire up the scooter periodically to keep fuel moving, even when it's cold & raining or snowy during the winter. I try to run it for 15-20 minutes every month to keep the fuel system moving fuel & to prevent fuel from sitting in the fuel pump, line, filter or injector too long. I do the same for our pressure washer & backup generator. I run them for 10-20 minutes every 30-60 days to keep fresh fuel moving. I also top off the tanks with fresh ethanol free gasoline with Sta-Bil mixed.
