After crunching the numbers, it will cost me less to purchase generic gasoline from high-volume stations and add RLI Bio-Plus cleaner at 1 oz/10 gal than to purchase top-tier fuel. With this new combination, I can actually save $10/mo! In theory, generic gas + RLI Bio-Plus should result in a fuel that has significantly better cleaning capabilities, right? Is anyone here using RLI's fuel injector cleaner? Also, any analysis of how RLI Bio-Plus Fuel Injector cleaner compares to LCD's FP Plus product?
