Should I use Prem. or Regular/with flasher

[Anthony Creegan]

Well Trac almost loaded and craptrailer on back loaded with toolbox's (2000 pounds+)and other stuff. Would it be worth while to use high test for the 500 mile drive or just leave it set to regular unleaded and tow that way? :huh:

Regular for towing.

I swear that when I run e-85 my truck has significantly more power. No dyno numbers to prove it, just feels faster, plus the alcohol runs cooler reducing the possibility of pinging/detonation.
