I have a chance to get non ethanol fuel for the near future. I have a
2.6l 200 hpdi with hydrotec heads tuner and reeds. Before I was encouraged
to run 91 octane 93 was not necessary. This ethanol free is only in 93 octane.
I guess my question is is the 93 going to be worse for the engine than running
the ethanol and 91 octane??
