whould it be worth adding a few gallons of racing fuel per fill up on these truck my local gas station sells 93 octane and also sells racing fuel i was just think about it. thanks for replys.
If it is the Turbo Blue 110 leaded then no...it can bugger up your O2 sensors if used often......plus you will probably lose power without being tuned for higher octane.......higher octane gas normally has less energy per gallon than lessor octane fuels...

unless your spraying it wouldn't really do anything for you. Maybe if you had a tune to run a few more degrees of timing and had a detonation problem then you'd need the racing fuel but on a pretty much stock truck(even with a mail order tune from any of the vendors) it's not gonna do anything for you.
