Anyone ever used OWS(germany) additive products?
Isn't it also a selling point with their fuel..chevron gas with techron in it??
how does that compair to sea foam?
I am jumping into this thread late and know absolutely nothng about engine fuel additives, but I had wondered in an earler thread whether the alcohol content variation in gasoline from region to region may account for some of the variability in performance (both speed and mileage) we see from owners on these threads/ SB's comment above on this thread regardign the potential to "fool" the oxygen sensors make we wonder that again. Thoughts? Nigel
