Anyone here ever use this stuff in their Ecotecs? From what I have read on quite a few different forums this stuff seeems to be pretty good, and not a snake oil gimick. It also seems that the GM Fuel System Treadment is also idetical to what the Techron treatment is. I have been thinking about trying a bottle through my car since the past few tankfuls I have been getting a sulfur smell after doing hard acceleration. About to swap to a different Shell station. Plus I figured I may not hurt to run something through to clean the fuel system up, seeing as I have never put any kind of additive in the car.
Are there any negatives or downsides to using something like the Techron Fuel Trreatment in the Ecotecs?
