Many of the good brands of gasoline have additives in the formula. I had a healthy dose of an additive make a check engine light go off. That's only once in over a million miles of driving.
Premium gas has additives, regular gas no. Injector cleaners remove build up on injectors, don't know why he tested spark plugs. I use sea foam, seems to work, my last car had no fuel problems after 21 years of use.
