    Pagtatalo ng 4 na magkakaibigan na walang engineer. Humaba ang usapan at inuman ng walang conclusion.

    Pros: tipid sa gas, di masisira agad ang clutch lining, masaya habang nilalaro ang kalye sa pag tantiya ng speed at traffic.

    Cons: delikado, walang kontrol, matic auto ko bakit pa?

    Ano ba talaga advantage at disadvantage?

    With the advent of DFCO, there's no need to free wheel anymore.

    Ginagawa ko lang ito kapag manual ang dala kong sasakyan, takot ko kasi pag matic baka masira pa tranny kapag biglang pasok sa D habang gumugulong ang sasakyan.

    Di maganda gawin sa automatic ito, kasi pagbalik mo ng kambyo from n to d4, ang lakas ng transmission shock nito kasi dadaanan niya padin ung sequence na 1, 2, 3 & then 4 (depende sa speed). Kahit sa ordinaryong stoplight hindi ako nagneutral.

    Sabi ng iba malakas daw sa gas, sabi ko naman hindi rin. Parehas pa din kasi hindi ka nakaapak sa accelerator so meaning di magiinject ng fuel na more than sa minimum.

    Kaya pansinin niyo pag nakastop at naka neutral medyo mataas rpm, pagnaka-D mas mababa rpm.

    Kaya ako ganin kasi ayaw ko ng transmission shock kakakambyo.

    DFCO meanse that your penalty for staying in gear is very minimal. But DFCO also causes enhanced engine braking.

    Sometimes, it pays to actually coast, because coasting down on DFCO results in much shorter coasting distances. Hypermiling freaks almost exclusively coast in neutral.

    As long as you don't engage the transmission again until after you've stopped, there's little issue. The clutch packs should stay disengaged. If you shift back into gear while coasting down, there is some issue, though most modern automatics automatically give you the right gear for the speed you're going, resulting in less shift shock (will still cause some wear, though).

    Ang pagbalik ng comeback...

    In older cars I think DFCO required minimum rpms of over 2500 so it wasn't as effective. Now though I notice that my Ranger goes into DFCO as low as 1500 rpm.

    So effectively coasting distance is also prolonged due to less engine braking.

    I still alternate between coasting and DFCO depending on the situation, but 85% of the time I just let DFCO kick in yo.
