V10 Higher Octane?
I have a 2002 F350 V10 with 235000 miles on it, and I have always tried to run the higher octane gas. Just wondering if that was a waste of money? Thanks Rich

I have heard from some mechanics that running high octane all the time in engines that do not specify it can clog valves or gum up heads or something like that? Builds up carbon or some such.
Years ago I had a 1988 F150 with a 5 liter V-8 (may technically been a 4.9?) with fuel injection. A gas station owner told me to try higher octane to see if I got better fuel mileage. I laughed at first, then I tried it.
After a couple weeks of numerous fill ups, I figured out that there was an increase in fuel mileage. If the price difference between regular and high octane fuel was 20 cents or less, I saved money using high octane. 20-25 cent difference, I about broke even. Above 25 cent difference, running high octane cost more. It was interesting.
I don't know if new engines are similar. Anyways, around me these days the difference between regular and high octane is 50 cents or more, so it is not worth it savings-wise.
I do fill up with high octane every so often when I am out of state (Connecticut fuel prices are impressive compared to neighboring states) just, well, because. Sometimes I do seem to get slightly better fuel economy, but not worth the big price difference.
