ethanol free gas, should I use ethanol free gas for my 1975 914 2.0? Options

I have a 1975 914 2.0, should I be using ethanol free gas? It appears to have the orginal metal gas tank.

That is a tooooon of work just to not have to worry about replacing your fuel lines with modern ones...which you should be doing anyway...

Mark Henry offered earlier in this thread how to check for the % of ethanol, that's the procedure we use to scrutineer ethanol in racing (SCCA has a max allowed limit). That's the same technique as described above to separate it.

But that's a lot of work just to avoid replacing your fuel lines with new ones...

GA, living in CT where "pure gas" is just a fantasy unless you want to buy it in 5 gallon pails...and wicked expensive at that...

Fuel lines are just the start - that is simple and should be done especially anything 50 years old - got to love stainless steel lines.

What about the steel gas tanks? and the aluminum and zinc parts of the carbs? What do we do with them? What about the 50 year old injectors, can they handle alcohol? They were never designed for it.

No simple answer. The ideal answer is something chemical to add to protect things - if it exists and if it is verified independently as something that works. This has had to come up with PCA members or other classic groups. Unless this is one of those "I can still get ethanol free at Joe's gas station so I'm not worried". That was me with Shell V-Power until now... no the sky may not be falling yet but it is time to start seriously thinking about it.

Yes, pure gas is becoming a fantasy everywhere... just a matter of time... the pure gas website isn't a very accurate resource anymore. Perhaps better than nothing, but I am going to invest in a small graduated cylinder to do my own checking... I don't want to be replacing my tanks and carbs, or wonder if my problems are now caused by the fuel I use.
