Which octane gas rating do you put in your F?
#1
92 or 94 octane?
I normally put 94 octane for cars requiring minimum 91. However a friend who restores classic cars said that it's better to just meet the minimum (91 or 92) rather than going all the way up to 94. He had some technical reason for that which I couldn't follow enough to repeat, but I'd like to ask what people's opinions are on that here... 92 or 94? (Assuming both are readily available where you are located)
Thanks.
Thanks.

I don't have a scientific answer for you, but it seems that those of us that can get 93 octane put down slightly better numbers than those that are limited to 91.

I choose 93 always if I was able.
#1 - Will run a little leaner and the car will not compensate for the 10% content and since alky takes a diffrent A/F to be sotich you end up with a little leaner burn which is usually good for more power on all stock cars.
#2 - Car will allow more timing if it was ever knocking due to altitude or other factors like hot day

Is it ok to use 93 octane gas contains 10% ethanol for the F
I always use a free-ethanol 93 octane gas for the ISF. But last week i was on the way home from work, i saw the gas light pop up so i stopped at the Citigo gas station to refill gas. But i did not pay attention until the pump stopped and i saw a little sticker says " Fuel contains 10% of ethanol " and i thought it will be ok because it happens only one time. But with 30 miles on the way home i felt the car run smoother and sounds like the car responds better. So i would like to get that kind of gas again for my F
Do you guys think is it harmful to go a long run for the F engine or is it ok to go with ?
Any ideas will be appreciated !
Thanks !

It's been my understanding that all automotive gasoline contains ethanol. I was under the impression that E15 (15% ethanol) was the standard these days. My truck is capable of burning E85, but there is only one station in town selling it, and I have no compunction to try it.
93 Octane fuel in the west? I wish

I would dare to say your car will run better filling up at a station that only sells E10. Why is that? Because all the big name top tier brands sell nothing but E10 now (Shell, Chevron, BP, etc.). Their fuel has the best additives which help keep your engine clean.
The only stations I've seen selling ethanol free gas are small no name stations with unknown or no additives at all. Obviously, the best of both worlds would be a top tier brand with good additives still selling ethanol free gas, but that is not the case at least in my area.

Depending on where you live, there are probably a few stations that offer non-ethanol (usually their premium).

I'm pretty sure it won't make any difference in the F. I don't bother with my vehicles but when I did my own yard work I made sure to use non-ethanol. I don't know if that even mattered. I was just always told ethanol can cause problems in small engines and marine engines.

The problem here is why i use the same grade of gas from the 2 different station and it gave me different results in performance of the car. The most importance is with 93 octane gas contains 10% ethanol saved me about 20 more miles in a full tank of gas
