I try to go with real world experience where I can. Maybe it's worth it, maybe it's not. I've always been irritated with fuel prices that are manipulated from OPEC on down to the local extortionist so I try to find the best bargain within reason. I haven't had a single fuel related issue with any of my vehicles. Where you would see the most issues is with higher compression engines that don't have variable timing etc. New computer controlled vehicles can mask/eliminate piston rattle/detonation and for good reason. You might ask what vehicles I've run the cheaper gas through routinely.
