Found out last week that a single loose injector can cost you 2 mpg on a Cummins ISX
I was digging through some old fleet maintenance reports from a shop in Nebraska and saw a pattern I'd never noticed before - they tracked fuel economy before and after injector replacement and the gain was almost exactly 2 mpg every time. Has anyone else seen that kind of jump or was this just a freak case?

Woah, that's a huge jump... 2 mpg from just one injector is wild. It makes me think about how small, broken parts can quietly eat away at efficiency in so many things. You see it with everything like a fridge door not sealing right or a tire a little low on air... these tiny failures just compound over time. It's like your body with a slow infection or something, you don't notice the energy drain until you fix it and feel brand new again. Probably a lot of fleets are running around with a few loose injectors and no idea they're leaving money on the table.
