Maybe in the past, but 30mph in fifth at just above idle, is very jerky with a 21st century schizoid ECU. I'm keeping the revs over 1,200.

Works a treat and takes all than nonsense of left leg pumping and silly stick waggling away... Kev

It still means an extra level of schizophrenia, even if it is being given treatment to limit the jerks.

I just tell the jerks to belt up and let me concentrate on the driving... Kev

The fact that a lower gear can (*) put more torque to the driveshafts is not a proper explanation for the advice to use a higher gear when it's slippery. As such, it is the old wives' explanation. I am not an experienced ice driver so cannot claim the advice is fundamentally wrong but, if it is good advice, I am interested in something that's more technically credible. (*) The important word being *can*. Not *must* or *will*. |
