What is the difference between these 3 cleaners? I would like to use the one with the highest percentage of PEA. Which one would you use? 1. Gumout Regane Complete Fuel System Cleaner 2. Gumout Regane High Mileage Fuel System Cleaner 3. Gumout All In One Fuel System Cleaner with Ethanol Treatment Sorry for the crappy picture, I didn't look at the picture until now.
