Yep I get that...but the difference between 9:1 and 14:1 should be constant at any given RPM or load condition correct? Such as 9:1 at 4500rpm at WOT is ~140% of the fuel consumption of 14:1 at 4500rpm at WOT right?
If someone came to this forum and was like; "I used to get 30 mpg now I'm getting 15 mpg. I'm driving the same and I don't see any leaking fuel, do you think my plug wires need replacing?"
We can say, "Hold up man/woman...chances are you have an external fuel leak that you are not detecting cause your engine wouldn't even run if you doubled the fuel amount into the cylinders. You better start at the tank and move forward looking for a leak."
So I was wondering if A/F ratio on average would translate directly into fuel consumption with all other variables being constant...I'm guessing it does. This will help me troubleshoot my own cars in the future...thanks for the feedback!
