I have a 2005 Dodge Neon. I've been running E85 in it for almost a year now with no problems. The only thing I did was swap out the injectors with ones from a Ford Mustang that have a 25 percent greater flow rate. The computer did the rest, without a tune.
@BlackthumbTV10 ай бұрын
I'd love to see the computers learning values. Also, have you ever had to put 93 in due to lack of E85 in the area? We have E85 in most parts of this area, so not a huge risk to go corn-only here, but those long trips would be sketchy.
@dzim88229 ай бұрын
@@BlackthumbTV I have added a couple gallons of regular 87 gasoline a few times when I was running low and wasn't close to an E85 station. It ran fine and I actually couldn't really tell a difference. It probably just ran a little rich. For long trips, I run the tank down to less than a gallon and swap the stock injectors back in. Then I fill up with 87 gasoline and disconnect the battery to reset the computer. I did this before a 500 mile road trip during which I used 87 gas exclusively. I don't think the stock computer advances the timing when the E85 is added, so I don't think using regular 87 after using the E85 has any effect on predetonation (knock).

Fun fact, Amazon sells e85 ethanol distillation systems so you can make your own fuel. Another fun fact, ethanol fuel was founded by Henry Ford which he called gasohol and every Ford vehicle till 1974 was designed to run on it. Ford was paid by oil companies to run vehicles on gasoline. But before gas stations dotted the maps people made their fuel at home with Ford's fractional distillation system. Amazon also sells e85 conversion kits for most vehicles. Enjoy your freedom from the pump!

I used to run E85 in my 96 Lincoln Towncar. That car loved it. Engine light would come on for the lean code. But it wasn't that bad, aside from its higher octane rating, ethanol also burns cooler. And it's great for cleaning carbon from the valves, pistons and heads. Similar results running corn juice in the 2003 Chevy 1500 van and my 2016 Ford Flex. When it was time for annual state inspection just run it low and refill with normal gas and the light goes away. Yes, all 3 cars had improved power, all 100% stock.

Love all the plot twists throughout the video, every single time I was about to write a comment addressing a caveat it was immediately addressed. Something that wasn't addressed though is that your stock fuel pump might be too weak to supply fuel to all injectors upon an upgrade, I've only seen this happen to really old cars which were due to have it replaced in the first place though.

Fun Fact: In Brazil, Ethanol and Gasoline are the norm of fuel. Diesel is only for trucks. Ethanol gives more power, but more consuption. The gasoline is the opposite. ALL Vehicles from after 2005 have Flex Fuel Capabilities. Great video to see how a normal car behaves with Alchohol. (In Brazil its made with Sugar Cane). The car with Flex Fuel can run in ANY mix of gasoline and Alchohol. But it has its downsides, as the engine is "bogged down" having to work with two fuels, and there's a saying that goes somewhat like this: Flex Fuel Engines are Engines that are made to run Ethanol, that are forced to run with Gasoline. There are engines that when running in 100% Sugar Cane it gives 5 hp's more! (its not insane but its quite a bit more power).
@gabrielv.43587 ай бұрын
In 2003 VW Launched the Flex Fuel with the Gol G3 1.6 Power, and generating a whole new Flex Fuel ecosystem here. (In the late 70's and mid 80's when the fuel crisis came, we found out about the sugar cane fuel, and to prevent having no gas, vehices from that era, specially after 1976, were manofactured to run on Ethanol instead of Gasoline, with cars returning to gasoline in the mid 80's) Specially back then, the Ethanol vehicles needed special carburetors and fuel systems to handle the water on the Alchohol, that could corrode the normal carburators and rubber hoses.

i ran E85 on a Stock Citroen from the early 90s for quite a while, you need to slowly change over from normal fuel to E85 and back, if i quickly changed over it then went into limp mode and got the same issue as you did, i am guessing the ecu might be able to correct both long and short term fuel trim and thats why it's fine? I don't really know tbh, it just worked.

the regular gasoline lubricates the rubbers and casings of everything in the fuel system. stuff will start becoming brittle and cracking leading to shorts in things like the pump if you run e85 too many tanks before switching back to regular fuel. I like the idea of mixing the 2 getting the best of both worlds with low knock from e85 and lubrication/longevity of regular gas.

I have an 09 Impala that is a glex fuel ready vehicle and I just stsrted having the issues starting when its cold due to the sensors thinking its starting out with more fuel than it actually is. If I press the gas pedal a little it starts right up which is a known issue with these vehicles and replacing my Idle control sensor or Cooland temp sensor should fix this issue in my case. My point is that even in vehicles that are E85 ready the CPU can have the same issues if a sensor starts to malfunction or the ECU cant properly detect which type or what mixture of fuel is actually in the tank.

I see a few common questions, so here's some answers! - E85 is better for performance engines as it has a ~105 octane rating. Research how octane rating effects high compression and boosted engines for more info. - E85, while technically getting "worse mileage", is still cheaper doller-per-mile than 93 (at least in my area) - E85 burns much cleaner than petrol meaning less carbon deposits, and even tends to clean existing carbon off engine internals. - The jury appears to still be out on whether or not it's "environmentally friendly" on the whole, I see sources on either side of the fence. - "IT RUNS FINE IN MY NON-FLEX CAR!": Some cars ECUs will learn around the additional fueling requirements different than others, this is an example of what can happen and how it can cause damage. Show me datalogs, then we can talk. None of this is new, this info has been around forever. All we do is show the literal data coming from the car in the real world and describe the potential ramifications.
