So, why, or how, do we see videos of fouled injectors and after adding cleaners, we see them spraying better??
I'm pretty sure it's easy to get fouled injectors by simply using a non-detergent base fuel. That'll foul it up pretty well given enough time.
As for switching brands, I'm thinking that's probably not needed these days with a properly formulated additive package. I'm pretty sure that additives are better balanced to clean up what they might otherwise leave behind. The real key these days is that they run them through tests with performance standards and quantifiable results showing clean injectors and clean valves. So if detergent A cleans up the injectors really nicely but tends to foul up the valves, then it would have to be balanced with something that cleans up the valves.
I think there was a problem with 80s to early 90s era fuel injector detergents cleaning injectors but fouling valves. That was before Chevron developed PEA detergents. Their brand name at the time was Techroline.
