our three kids from Grammie's house. Grammie and Pop-Pop took the kids
earlier in the week for an extended visit, and we intend to pick them up
over the weekend.
We're undecided as to whether take the Corolla, which will get very good
mileage, or the minivan, which is lucky to pass 20 mpg. The passengers
will be just the two of us for most of the trip, and five people for the
trip home from Grammie's house- about a five-hour trip.
Last night we were leaning towards using the Corolla, but the more we
think of five hours in the littler car with three kids across the back
seat, the more we think the added space the minivan provides would be
helpful.
I will continue to assume we will take the Corolla. This will mean I
must fill the gas tank today before I get home, which will mean a
refueling after 7 days instead of the 11 that it would be had I waited
until Monday.
But filling up in the heat of the day will help me a little bit to see
if there is truly a difference in fuel economy figures when I fill up
with "hot gas" during the hot afternoon instead of refueling with
"cooler, more dense gas" in the early morning.
Historically, I don't see any particular trend in fuel economy based on
heat. If anything, my mileage is better in the summer and autumn months
anyway, which doesn't lend any credibility to those who say "hot gas"
gives you worse mileage.
I think you should be able to fit the kids in the back. The good thing is that they are still small. Take advantage while you can!!!!
