Princessauto has Gumout multi-system tune-up or fuel system cleaner for $9.99. This is one of the last products on the shelves that still has PEA. Canadian tire has it for $17.99. This product works for port injection engine. Put it in the fuel tank, and you will feel the difference right away when the tank is almost empty. If one can’t realize the difference between Eneos, Motul oil, vs Costco oil when driving then please DO NOT buy it. (It’s not placebo effects). This gumout multi-system is the only gumout product that is still works. Other gumout are garbage event though it says GDI on the bottle, they don’t even work for port injection engine (However, the same product did work fine 10 years ago, no information on what change in the formula except no more PEA). For an extended period, I have tried almost all products at Canadian Tire, and this is the only product that still works for port injection engine to this day (nothing work on direct injection engine, it all marketing scams) . Of course, one could buy Royal Purple or Red line, or drive to US Wal-mart to buy Chevron but at what price.
