I fear if you didn't feel a difference with REX X
you either have no varnish issues

or if you have issues with stiction it's beyond the snake oils ability to dissolve?

so 9100 won't be any better or worse however it's cheaper so I have run it just for PM even without having issues

but you don't have your truck in your sig so I don't even know what injectors you have

stock injectors. Theres a light miss right at 2000 rpm. only at 2000. Nowhere else. Irritating.

power balance test is fine. COntribution is fine. Injector kill has good stumble when each one is killed. Maybe an unhappy glowplug?

+1 on ArchOil ar9100.

IME, the additive helped quiet the engine chatter, ran a bit smoother accelerating onto highways & it was cheaper than others. AFA mpg increase, just barely, not significant. Mainly, I'm interested in engine performance, efficiency & longevity, even if it's just a little bit. I have not tried the other brands, so I can't compare & don't think I need to, I'm satisfied.

AR9100 worked like a charm on my 2004 6.0 PSD. Mine had serious cold start issues and miss until operating temp. 16 oz patched mine 100%. Never used Rev X so not sure if its better or worse but I'm not switching...I'm satisfied with a HUGE smile.
