What has changed is the additives that come in name-brand fuel are a lot better than in the past. Both the 1972 Buick and 1987 Dodge have sparkling clean carbs. They get mostly Chevron gas. The problem did disappear indirectly because of fuel injection. The newer detergents were developed because of clogging fuel injectors.quote:

Working on classic cars with my Dad when I was younger, the number 1 thing we did was take the carb off take it apart and clean it out. Did this problem suddenly disappear with the invention of fuel injection? Or is it a problem that modern fuel and computer controls hide better?quote:

the reason you dont need fuel system cleaners is for the exact reason you just stated. the gas companies already put the stuff in the gas. you dont need any more additives than what they already put in.
i know some gas companys dont use the epa required ammount of additives but they are cracking down on this so its not a big deal. if you get a couple bad tanks of gas it does not matter.
