Techron rocks! I always use Chevron gas, and now Texaco has Techron. I also run a tank treated richly with the Techron additive before every oil change. I've done this on all my vehicles (cars & bikes) for many years and I just never have fuel system problems.
I have wondered about who's gas has the additive...we have a large gasoline terminal east of town, and we were replacing utility poles nearby one afternoon. An Exxon, Texaco, Shell, Diamond Shamrock, then a Citgo tanker ALL pulled in to same bay as we worked. There is a large gasoline producing refinery in the Texas City complex 300 miles away that produces for several brand names. ...Trying to remember the name, Marathon maybe. It is not one of the biggies. I worked for Exxon in the early 70's, and know they also refine gas at some of their facilities as do the others, but makes you go HMMMMM?
