Normally, I can do 70 or 75mph without any issue. I currenly set my cruise there and almost never have to make any adjustments. Also, I'm in Atlanta so its not cold very often. I park in the garage at home so its always 60F+ for the morning start.

Thanks. So the carpool trip is 8 miles each way. I won't be negatively hit on my mpg due to the trip being so short and the ICE being cold to begin with?

So my job is 84 miles round trip, 74 of those miles are at 70-75mph going with flow of traffic. I carpool most days and the meeting spot is 16 miles round trip with it being either all streets or half street half freeway (50-70mph) depending on which route I take. Every 2nd-4th carpool, its my turn to drive us to work. To summarize, here's an example work week. One day drive alone, 82 miles round trip. Two days I carpool as rider, 16 miles round trip each day. Two days I carpool as driver 87 miles round trip (70 highway miles at 70-75 mph). With carpool I do just over 17k miles per year. What I'm trying to figure out is will I be able to avg at least 38mpg with this car for my non-standard commute cycle.

I thought diesels cost more to maintain?

Same question. Would like to install a sub if I buy one.
