When it is not steep downhill and you don't need to brake the car to slow it down, coasting down around 55 mph at idling gives the engine a rest also save gas. Just not sure if the vacuum and other stuff are operating at normal level

50% comprehension isn't good, the other stuff generally operates well. That depends on other circumstances as well. Saying if you can't park parallel, and won't learn to then don't. Same for driving in reverse due to a driving error......(a BOO BOO....)often wastes gas! Stay Happy.....

Very stupid thing to do as the transmission works in con junction of speed and you will wear your brakes out very quickly as well as over heat and Warp rotors

I've heard people who downhill in neutral are known in the medical field as organ donors.

I have driven two 5-Speed pickups with a manual transmission since 1985. Over time you learn to hypermile just for the sake of keeping things interesting. My 2002 Tacoma gets around 27 mpg in mixed traffic.

Redfish, you keep repeating an opinion but don't provide any support. Several have posted how it isn't stupid, except for those without the background to understand what is happening in a manual shift vehicle. Nice thing about opinions, everyone is entitled to them, and others can ignore the ones that don't have much merit.

I had tested on a number of occasions to slow down on a fairly long stretch of downhill coasting in gear vs. coasting on neutral. Result is
that coasting in gear I ended the slope with 35 km speed whereas on neutral it ended with 48 km
This proved to me that going downhill ( of course not too steep ) saves quite a bit of gas as towards the end of the slope I just accelerated from 48 km instead of 35 !
Good topic just has to understand how the car works
