Ever since gas was real expensive I’ve been doing my own hypermiling variant which involves taking the car out of gear and coasting when it makes sense to do so.
At the dentist recently I was reading a car magazine that talked about ‘fuel efficiency myths’ and it said that fuel injected cars do no better coasting than they do with your foot off the pedal, so keep the car in gear in case you need some revs. There is no gas saving.
I’m no car expert but I can see the rev counter at 3k rpm compared to 0 and it seems to me that means gas is being used, although it might be small.
What do you all think?
