fuel economizing driving technique?

late contribution...

tried driving around (city, highway) using the hold function ng a/t (gen 2.5 pajero), mas tipid. :D

lower top gear equates to better vehicle acceration up to desired cruising speed?

[nugundam93]

not actually ghosthunter.

what the a/t did when under "hold" mode was it wouldn't rev higher than 3K rpm during acceleration and the redline ng 2.8 pajero is about a bit over 4K rpm. it usually shifts at 2.3K rpm and rarely goes higher than that unless the gearing is so at higher speeds. acceleration-wise, bumagal, pero i'd say it's worth it naman, alis na lang ng mas maaga if ever. :D

anyway, the pajero ain't a drag car, so okay na kahit mga 120 max on hold mode.

running in neutral at high speeds WASTES fuel compared to just engine-braking.
when you're in neutral, the engine is idling and consuming fuel. when the engine is engaged but you're not pressing the gas, the ECU will CUT OFF FUEL TO THE ENGINE. so the engine will not be consuming fuel at all (of course the vehicle will slow down a lot faster).

wow kala ko mas consuming pa pag nagdownshift or engine braking kasi tumataas ang kamay ng tach. Mas nagconsume pa pala pag nag neutral, is this true parang hindi pa din ako makapaniwala (just a question)

coasting in neutral will only save if you're trying to maintain a high speed. Coasting to a STOP in neutral wastes gas. In most traffic situations, it's better to coast in gear.

The HOLD function on the AT allows it to engine-break. Kung naka-OD or OVERDRIVE, an AT will coast in the highest gear available, and go into neutral/freewheel when below the torque-converter brake point (usually between 2500-3500 rpm). When it's freewheeling, your engine is using a lot of gas to turn the engine crankshaft and torque converter, which weighs between 30-50 pounds... heavy!

But on the highway, you should turn off HOLD or turn on OD so that you can maintain lower rpms at high speed.

the hold on the gen2.5 a/t pajero allows it to actually use the lowest possible rpms at high speed. the normal a/t function kasi sometimes lets the engine rev near the redline before shifting, while the power a/t function downshifts quickly once the gas is stepped on, unlike normal and hold modes which most of the time still keeps current gear if the gas is stepped on and it normally doesn't necessitate a downshift.

argh. i dunno if i was clear...me still hungry. ehehe.

I thought the Hold button in most automatics are for instances wherein you wanna hold on to a specific gear and not downshift or upshift. Because when i was driving in slippery muddy road, i noticed the Hold button light will automatically light up temporarily when i loose traction on accelerating from stand still. I expected this to be correct since i saw the RPM became higher yet i wasn't moving. It was holding me to the lowest gear for more traction even as the RPM grew higher which in normal mode should have had an upshift.

That's how the Mazda AT works...though it also permits downshift and upshift, you just have to do it manually in the shift lever.
Mazda's Hold button functions equivalently to an Overdrive 'Off' driving.

~i drive a Diesel, so i shift early for as long as the next gear can already catch the RPM.
~no AC for short driving.
~if im driving without AC at high speeds, i even sometimes close the windows to reduce drag.
~maintain a good distance to the car in front of you, so as to avoid sudden stops.
~if in the highway, i like trailing those trucks, busses or any fast moving tall vehicles because drafting reduces drag and permits less fuel consumption...ingat lang ako at naka-airbrakes mga yun.
~at syempre,,,konting pigil sa pag-hataw

will this hold as with the lancer MX with invecs? kaso walang OD or hold button...

Puwede namang i-manual shift ang INVECS... pero from memory, it won't let you shift up at a very low rpm, right?
