Wow, I'd hate to drive a car that used 2-3 gallons for every km.
30 miles = roughly 50 km
1gallon for 50km = 2 gallon for 100km = 9 liters per 100km. That's best
case. Roughly 14liters/100km worst case.
22liters / 100km = 6 gallons / 62 miles = 10 mpg.
That's really bad.
My 2003 325 gets a lot better mileage that does the OP's 525.
For example, in local driving 22- 24
On the highway, less than only 60 mph, 34
On the highway, less than only 80 mph, 32
One of my son's friends drove a 525 to Colorado last summer, and he said
that they averaged 31 mpg. I. E., about the same as my 325.
Either the OP's math is all wrong or there is something very wrong with his
I zero the OBC each time I fill up my 528 auto, and the worse I've ever
seen was 16 UK mpg - all short town journeys in heavy traffic in winter.
Very best 37 mpg long distance motorway only at 70/80 mph.
