KeychainDan said:The Nissan manual says to turn off the overdrive if you need more engine braking (i.e. if you're coasting down a steep hill). Overdrive is basically letting the engine run at a higher rpm, meaning it is running at a lower gear ratio. Higher rpm = lower gas efficiency, so I would suggest leaving it on unless you are trying to tow something or drive in San Francisco.
If you are used to a stick then think of it this way. On a 5-speed standard transmission, overdrive is 5th gear. If you have overdrive off then at higher speeds you have been driving around in 4th gear. While it’s a little peppier, your gas mileage is suffering.hana said:??? i'm confused about the overdrive, i thought my sales guy said to leave it off ?? is it automaticlly on , i've driven stick my whole driving life first ever automatic car, i miss my standard, but i love my cube ;D
