Fuel

Ethanol has a propensity to degrade rubbers and other items.



Granted, cars manufactured past the mid-90s SHOULD be more suited for ethanol-blend than those made prior; actual engineered-in compatibility ranges by manufacturer. My '92 integra I had in high school (growing up in central iowa, home of the raw materials) ended up needing a new pump and hoses after about 2 years of running it on the cheaper ethanol blended fuel. Back in those days 87 was still non-ethanol and since it was only the LS model, I just did that from then on. Happy times.

All other factors notwithstanding, it shouldn't have any negative effects (assuming you still use proper octane of course)

 

Ah, roger. I'd stick with proper octane rating (91 minimum, even at Reno's elevation i wouldn't go lower)

 

I use 91 Octane, ethanol-free. Very happy with that.
