OK. Noob owner of a 2018 stock Mirage ES (Automatic transmission) here. Just bought it used with...get this, only 10k miles on the clock. Why the original owner put so few miles on this baby I don't know, but it's pristine. Before you ask, I bought it off CarMax, who are notorious for buying it back within 30 days...and the first thing I did was run about 500 miles on it, then take it to a mechanic & have him do a stem-to-stern, top-to-bottom inspection. It's clean as a whistle. AND...the original owner never registered with Mitsu as far as I can tell, so I may be able to claim the 100k powertrain warranty.

On to my question, which will probably start an argument among the hard-core gas-mileage tweakers.

Given a relatively flat & straight travel path...what's the "sweet spot" for speed & tach, to set the cruise for highway travel? I have to travel 40 miles each way to commute to & from work each night for work.

Thoughts?
