I use only Top Tier gasoline, per Toyota’s guidance. The stations that sell Top Tier do not have ATMs that I can use freely. If I want gasoline, and money from a free ATM, in the same place, the gasoline is not Top Tier.
In place of Top Tier gasoline, do those treatments you can buy in an auto parts store, or discount department store, have the same effect as Top Tier gasoline?
For example: Fill up the tank with Joe Schmo’s 87 octane, and add a bottle of Gumount fuel injector cleaner, or STP’s Oxygenated Gas Treatment.
