Miles per gallon
 The highlander hybrid I purchased has a mileage rating of 28 highway and 32 city.  This would make me assume the mileage would not average less than 30 per gallon.  I have been trying my hardest to "work" the battery for better mileage, although the best I can average with this vehicle in any condition is 27.5.
