Q--Is it necessary to periodically clean the fuel injectors? If it is necessary, is filling them with a couple of tankfulls of name brand, premium grade gas a good way to clean them, or do you recommend adding fuel injector cleaner to the gas tank?
My Civic and New Beetle both run fine on regular-grade gas from discount gas stations. I have read that name brand, premium grade gas contains superior detergents to the discount gas, and wondered if an occasional filling with the good stuff would obviate the need for using additives.
A--A regular diet of brand-name gasolines should keep your injectors clean so no periodic cleaning is necessary. But you are intent on saving money at the pump and shop for the very cheapest gas, you may want to occasionally dose it with an additive.
