First. Greetings all. I found this forum and though not in my language try to expose my query. I hope you understand me
Is it true that the use of a very low engine speed is counterproductive to fuel consumption with respect to use more speed?. Sorry for my English. (I'm Belgian). My question is based on my car consumes less so in fourth gear to fifth cruise, when I have the feeling that in fifth gear would consume less. Thanks for your time in this great forum.
