I have heard about not needing the higher octane, and I doubt this 360 has been modified in any way other than being clean and kept well oiled, cooled, and in general good shape, but it's not just me that thought it runs better on the higher octane. The wife and daughter both asked me what I had done to get it running better which made me think and the only thing I could think of was the gas... Although I did recently adjust the choke and fix the heat tube so perhaps it was that now that I think some more. I'll blame it on eating too much turkey and pecan pie.

Thanks all.

You can blame it on the tryptophan that naturally occurs in the turkey.

Prices here are at a record low and I'm paying the US equivalent of $5.20/gal.

That's mostly tax, then.

You should consider moving down the road to Washington.

If I remember correctly The higher octane's slower burn rate gives a possibility of a little more timing,right guys? Kinda like with the extra heat absorption of aluminum heads they like less timing than cast iron heads. So,if OP's truck had the timming set more advanced than it wanted the Premium fuel would indeed help. My head hurts.

Your right Jeff. I've got mine turned up to the edge on regular. I put in premium when I plan on hauling/ working the engine hard. Such as pulling the hills on highway 87.

Definitely noticeable when a bad batch of fuel slips through, if the timing is advanced in excess of OEM. Modern engines have anti-knock sensors built in of course.

Didn't Model T's have a "spark lever" or somesuch to retard timing during starting? An adjustable distributor (from the cab) would be sort of useful at times.

I know MSD and them make a system that you can turn a **** and it adjusts timing. But that crap is expensive and complicated. Two things I don't like....

Yes and a magneto ignition.

Once I filled my 240 '67 with 92 octane. After, I floored it on the freeway at 55mph. Fifteen seconds later I was going 58.
I think it bleated a little louder.

It is entirely possible that you went from a lower grade that had a percentage of alcohol to a higher grade without any. In which case it probably does run better.
