Re: 93 octane fuel
Shouldn't need that high an octane fuel unless you are running a high compression ratio. But to high an octane shouldn't cause a driving issue. How about bad fuel? I have seen several cases where the fuel (at the supple station) is contaminated with something, like diesel or water, etc.

Re: 93 octane fuel
The chugg description will need further clarification. At what rpm is this chug and is it when the engine is under load or no? Engines will miss and rpm fluctuations can happen under certain conditions but the only thing that chugs is a steam engine in my way of thinking. Stuck valves can cause after fire in the exhaust and a lean fuel mixture can cause backfire through the carburetor. These would be like the definition of "chug" when related to motor vehicles.

Re: 93 octane fuel
The question, as asked, cannot be answered. Please define what "chugg" means? Running octane much higher than the requirements of the engine can cause some performance issues but I would not refer to that as being a "chugg".

It doesn't have any more energy or higher performance. In a flathead it is a waste of money.

Re: 93 octane fuel
I run non ethanol fuel which only comes in 93 octane in my area, no problems in my ‘41 or the snow blower, lawnmower.

Re: 93 octane fuel
My impression and my friends who have used higher octane gas in a variety of vintage vehicles is the car runs better -However its probably pyschological rather than scientific . The same pyschology that gets millions adding useless fuel additives to the gas tank.

Re: 93 octane fuel
I think he is referring to non-ethanol gas. I agree 100%. The ethanol gas causes havoc in small engines and motorcycles if left to sit for any extended period; even with Sta-bil, etc. in it.

Re: 93 octane fuel
When my dad was growing up in SE Massachusetts in the '30s, they lived behind his stepdad's gas station on rt 6. They sold something like 8 brands of gasoline. Flying A, Mobilgas etc and the loyal customers would swear by their particular favorite brand of gas... "ol Bessie won't even climb a hill on the cheapass stuff you're filling up on". Well, years later Dad told me they only had One underground tank and it was re-filled at night by a flat black painted fuel truck...
