Bad Injectors. Good MPG

My '76 (stock) engine started really smelling like gas. My mechanic (trustworthy) says it's still got the original injectors and parts and they're leaking all over the place. So why am I still getting close to 22MPG? Shouldn't bad injectors = bad MPG? :?:

 

Any thoughts on this, and if I need to change them over, does anyone have a good suggestion on what to replace them with?

Sounds like the hoses are leaking. When my 280Z was stock it got awesome MPG, like 25 - 26 on the highway. I never understood why, when I'd stomp on it, it would pop into the intake. I had it diagnosed 6 ways to Sunday. Mechanics told me to replace the AFM, check the fuel pressure, fix vacuum leaks, pumped in the injector cleaner, never had any effect on it's condition.

 

Anyway, the injectors started leaking after a while, and I replaced the set. WOW! The car woke up! No more popping, it would get up and go. MPG dropped like a rock, down close to 20, but it sure ran nice after that. I actually tested the old injectors for flow - they had horrible spray patterns, and flowed significantly less fuel than the replacements (stock injectors).

 

Moral of the story...sometimes bad injectors = good mileage.

 

Next week: When GOOD spark plug wires go BAD! ;)
