Techron & Redline S1 both have a high level of PEA. If you want to “clean” the fuel system I would recommend one of them. If you are looking to mitigate ethanol fuel woes I have used a 50:50 mix of Startron & Marine stabil for many years. Before winter I used the 50:50 mix as well as filled the tank with non-ethanol 100 octane street legal fuel which is available near me. Otherwise, I always filled my Viper with Shell 93. That was the factory fill on the GEN V for the Viper as well as for Ferrari. I realize it is about sponsorship & advertising but I believe it is good quality fuel as well. Always run Top Tier gas regardless.
