RPMs and MPG
Just got a question, prolly dumb, but im curious and dont know who to ask
Heres a list my RPMS at certain speeds: (01 Grand am 2.4L auto)
65mph = 2100RPM
75mph = 2500RPM
80mph = 2600RPM
85mph = 2700RPM
90mph = 2900RPM
I guess my question is, although gas mileage, per gallon, decreases after 65mph(rumor?)....wouldnt using an extra 500RPMS(80mph) to go an extra 15 miles be good? hope this question makes sense..
