Hi BMF,
The GT tank is confirmed to have components in it that are not compatible with ethanol. It was not tested but is not necessary to be tested since the component materials are known and are confirmed to not be satisfactorily compatible with ethanol.
No known or no perceived problems is not “NO” problems. Incompatibility is incompatibility and over time will affect the vehicle. Lower percentages of alcohol and less time in the tank will slow this process; however, over time it will affect the incompatible parts and most likely lead to a failure at some point. It all obviously depends on how vital that said part that fails is. Is it a tank lining that fails coming off and slowly over times clogs the injectors leading to a failed engine… is it a fuel line that rots from the inside out leading to a rupture and a fuel fire… is it simply an o-ring that slightly swells and never really causes a problem? As stated, each vehicle is different. It’s the owner’s/shop’s responsibility to make sure said modifications are compatible in areas of concern.
I’d have to agree here. However, it is a more harsh fuel and any extra care can’t hurt. I do believe that adding oil isn’t the best option… as Mark stated. Oil has a lower flash point than fuel and will aid in inducing detonation. As stated a different engine oil, one designed for use with Ethanol, is advised.
Ethanol chemically is a straight-chain alcohol. It is also known as ethyl alcohol, pure alcohol, grain alcohol, or drinking alcohol. We happen to use it as a fuel too.
When you state “Alcohol” I believe you are referring to Methanol… another form of alcohol. Methyl alcohol or Methanol is what “Top Alcohol” drag cars run and is chemically the simplest alcohol there is which is why some in racing use the term “Alcohol”. Don’t drink this type of Alcohol
Both Ethanol and Methanol are considered Alcohol fuels.
Both are capable of the destruction to engines you speak of under heavy detonation if the tune is wrong. We refer to it as "torching" the head or block because it resembles what a cutting tourch might do. The good news is the fuel is much much more forgiving than gasoline to an improper tune. It takes a lot of cylinder pressure (boost and compression), and a very far off tune up to lead to destruction of that magnitude.
Have to totally agree here… most do not know about or how to run any of the alcohol fuels correctly. I’m lucky to have started in pro drag racing running methanol on turbo fuel injected engines 10 years ago. It’s like anything else in life… can’t beat seat time.
Not trying to be confrontational, just wanting to clarify a few points
Cheers
