I m not sure if I understand you correctly, but the easiest way to calculate your fuel consumption is to monitor the odometer reading. Fill up tank, drive, then fill up again. From the distance travel, u can easily calculate the fuel consumption. Use fuelly for easy tracking, or if you're using android phone, fuel log will help too.


Edit: don't quite get you, but knowing the fc won't help in reducing the expenses, unless you do something to improve the fc.

errr.....your father is JFT63? Don't quite get you bro..... Or you mean your dad has an e39 like JFT63?

Reducing FC....depends on how you drive. Are you heavy footed? Rim size? Which engine is yours? You can gauge FC from your OBD (do check how to do so fm the e39 subthreads)....etc etc.....
