The proper way to figure mpg is convert
the you miliage to SmellyMiles or Sm.
Remember how many morning trips you
take per tank. record you average MPH
during the 1st 10 minutes of the trip.
You have to do this since Volvo
speedometers dont work in the morning
because the are cold and sleepy. You
have to wake them up by striking the
the dash while driving. After about 9
minutes, the Speedo starts working and
maybe even the Tach will come on. Don't
trust the tach though, its cranky in
the morning and over reports rpms by
1300. Fill up the tank, "Dont forget to Check for leaks".
Record the gallons
pumped, take the odometer reading and
add 10 trips x 45mpg X 9 minutes/ 60
min per hour to determine Smellymiles
or SM. SCMPG = SM/gallons pumped.
If you want to increase your mpg. Add
some gas from the lawn mower can
between fill ups.
I usually just buy a 30 pack of bud at the gas station because who the heck knows what this POS's MPG is. SC
