Any benefits to high octane
Are there any benefit to running octane gas when towing? I had heard when towing use high octane gas.

If you reduce the temperature in the combustion chamber by adjusting the timing, you also affect the conditions under which pre-ignition can occur.
Wait ? What ??
Pre-ignition occurs BEFORE the spark hits and the temp at that point is most dependent on the compression.....and overall engine operating temp too a little bit.
I'd like to see a reference for this claim you make.
Not that an engine working harder with an overall higher temp is more prone to pre-ignition.....but that spark timing alone will affect combustion chamber temps enough to make any practical difference in PRE-ignition.
