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 don't consider it a waste, esp towing in the mountains and hot weather. Higher octane will help prevent detonation under those conditions. Then the computer won't back the timing off as much or any. Most of the time, I don't use premium, but will if towing heavy in hot weather.
In reality the computer does indeed back off the timing to eliminate pre-ignition and does a great job. The newer Ford system is very robust. What year is your vehicle?
