Crap MPG question
Ok,
97 5 speed Disco, new plugs, new wires, new air filter (paper element), new oil (RP 10w 30). 73K on the clock. Not driven hard, at least not by me.
Historically we have gotten between 19 to 17 MPG.
Wife fills up today and does the math. 12ish MPG. She has a heart attack and throws the whole agreement we had about if it becomes too expensive to own we get rid of it.
No check engine light on, it runs fine, exhaust doesn't smell like its running rich, no black smoke when i accelerate hard.
Unless there is a code that isnt triggering the "check engine light" then everything is running correctly
I dont know much about OBD II systems, could there be something not working correctly and no check engine light?
The wife is from a tropical climate and thinks that 60 is cold, so she starts it and lets it idle for at least 10 min in the morning before she leaves for work, and the same thing before she comes home so its nice and toasty inside.
I suspect that this is the culprit. Letting it idle for a long period of time can consume a significant amount of fuel and make for the shit MPG calculation.
Any ideas?
