I thought I learned here that one of the keys to optimal fuel efficiency on flat road is to use cruise control and keep RPM low as possible between 2-3k depending on the speed and gear. I didn't hear nor feel engine lugging.
What do you think?
I use either the 1-3-5 shift pattern or the 1-2-5 shift pattern extensively in my OS. Skipping gears to upshift into the highest gear possible at the lowest possible speed is a time honored hypermiling technique. You can relax and not worry. I use 1-3-5 when there isn't much need for off the line acceleration shifting from 3rd to 5th between 25-30mph / 30-40 km. I'll use 1-2-5 when there is a need to accelerate shifting into 5th about 30-35 mph / 40-55 km from second. I also use cruise control ALL the time whenever possible. Even in the city as long as it's more than a few blocks I'll enable cruise. This is why my lifetime average over 47000 miles / 75000 km is just over 30 mpg / 7.8L/ 100km in the OS. With the manual 5 speed Mirage you should be able to achieve 50 mpg / 4.7L/100km no problem as long as you keep your speed down. With the Mirage it's pretty easy to achieve some really spectacular fuel efficiency. I know there have been members that have achieved 60 mpg / 3.9L/100km + so skip those gears!
