2008 BMW X5 4.8i: Fuel Economy Update
September 23, 2008
Many tankfuls of premium unleaded have come and gone in the life of our long-term BMW X5 since we last reported its fuel economy.
Our lifetime average is now 15.7 mpg. Before this update, it had been 15.9. Before that it was 16.6. I feel a trend.
The farthest traveled on one tank was recorded by Karl Brauer back in May: 364 miles (during which he got 17.5 mpg).
We've managed a couple tanks in the mid-18s, and a couple way down in the 10-11 mpg range.
Someone even pushed the fuel envelope once and waited until the 22.5 gallon tank only had .398 gallons left in it to mosey on over to the gas station. It wasn't me. I swear.
