Regular grade fuel only meets the minimum octane requirements that are needed for a Fit not to ping..... No where in the owners manual is it recommended to use 87 octane fuel, it just meets the minimum requirements only .... It has been proven that the ECU will adjust to to benefit from higher octane fuel.....My fuel mileage figures convinced me and it isn't costing me more than $1.00 per tank to use premium and, there is still an increase in performance and no need for additives to clean the injectors and possible carbon accumulations in the combustion chambers from the lesser amount of ignition advance.
