2008 Chevy HHR is reading 33.1MPG adverage at 43MPH adverage speed. I should have recorded the distance as well. But the test was roughly 16 miles long on back county highways. Flat land fuel economy while unhitched is down by 15MPG.
1) The spark plugs still have yet to be changed
2) the oil was changed, but still dirty from using the same filter
3) air filter still has yet to be changed
4) there could be a problem with the rear drum brake allignment?
5) the roof rack could be causing this much resistance?

2008 Chevy HHR LS has lost at least 10MPG @ 50MPH on flat interstate highway in North Central Ohio. Current mileage on the odometer is 126,405. The thick canvas roof bag is partially mounted, but one of its racheting straps came loose in the front. If it was full, the unit would be "boxy," or cube shaped.
The car is particularily dirty. The oil is overdue for a change. Tires are not at maxium pressure. Bicycle is not mounted. Manual transaxle fluid is overdue for a change. There is still resistance in the passenger's side rear brake drum. And the front passenger's side strut needs to be replaced.
