I filled up today after my trip to California last week and the average came out to around 28.4 mpg for the entire trip, that includes some driving around there and here but mostly freeway and highway driving. I think the average might have been higher if I could have avoided the traffic jams on I-15 heading to and from San Diego on Wednesday and the equally bad jams on I-10 coming home.
Most of the interstate travel was around 80mph with sections of stop and start... Most of the off freeway driving was around 40-50 mph.
Does that sound about right for a 1600cc Miata? I was hoping for a couple more miles per gallon but I guess it's not too far off, is it? I'm wondering what mileage others have recorded on overall driving (as opposed to all freeway).
