What do they mean by
junk gas??? If it's low octane (ie:
87) then yes maybe you should move to a higher number (maybe
91 or whatever is the highest pump gas you could get) and test it at 34 DEG and see if it pings. Keep moving your timing up until you hear it detonate, then go down 1-2 degs to be safe (as you sometimes may not
hear the detonation but it could still be happening)...My $0.02
