fuel economizing driving technique?

[RDL4D56]

this is something I've been trying... share ko lang and you guys can comment or criticize... in my daily trip to Cavite, I encounter around 10-15 uphills/downhills with clear traffic (example, I ride through a couple on daang hari)... I generally stay on 60-80KPH... with this in mind, on a long decent (not too steep) I would shift to neutral and let gravity help maintain or increase my speed (I feel I don't need to keep my foot on the accelerator and burn of additional fuel)... I shift back into gear when I start to reach 65-70KPH (but that is after a considerably long stretch when i hit level ground or an uphill while staying on nuetral)... I also shift to nuetral when I know I'm a few hundred meters from a stop (provided it is clear traffic which is usually the case in certain unpopular roads I pass through in Cavite)... I start using the brakes at around 100m from the stop... from my estimate, I feel I get an a little under 0.5Km additional per liter on my weekly drive (but that is just my estimate)... I guess, my point being it that on your daily route, if you know it well enough (conditions, traffic, etc)... you can create a tactic of your own to extend your milage.

i've tried yun method of maintaining my Rev lower than 2000. It works well. I've learned that from BMW. Yun BM kse has this approx gas consumption sa RPM gauge nila. Example is if you're rev is * 1500RPM ave gas consumption is 6 to 7km/L for a 316i model.

I just can't shift between 1500 to 3000 rpm. walang thrill
basta wag lang kayo lalagpas ng 3000 rpm

pag gusto ko talga humataw, I go all the way to 6000 rpm * 60-65 mph (84-104 kph) sa 2nd gear.

by the way, if someone owns a pickup truck...
might want to put the tailgate down because it causes drag. it adds 1-2 miles per galon sa fuel economy ko. mine averages 14 miles per galon

[ian_rex]

pare, ang lakas nyan. i converted your fuel consumption into kilometer/ liter, you got 5.6 km/liter. ok lang sana humataw basta maluwag ang daan saka makinis ang pavement. dito sa 'pinas, nakupow! bukod sa trapik, e grabe pa ang mga daan. kaya di uubra humataw- unless hanap mo disgrasya.

[ian_rex]

ang lakas naman lumaklak ng gas yang beemer sync3. A/T yan? in my experience with my Honda Civic, 10 to 11 km/l kapag trapik talaga pero pag super trapik, 9 to 10 km/l lang. basta nasa 2000 rpm lang lagi. dati napaabot ko ng 21 km/l yun e, kaya lang puro highway driving lang.

medyo hirap nga ako mag-adjust ngayon e. paano ba naman, sa isuzu, less than 1000 rpm, pwede nang pagulungin. e sa kotse iba, 1200 rpm. saka sa highway, iba ang timplahan ng gas sa diesel. knowing na yung sa gas e sa hig-end rpm pa bago masagad ang torque, i think mga 4000+ whereas sa diesel 2000 rpm pa lang labas na lahat ng torque.

di na rin ako masyado humahataw, ever since my fiance crashes her ducati sport bike
buti broken wrist lang inabot nya pati nakahelmet.
nasermunan ko yan dati for not wearing her helmet.
her dad was blaming it on me, though
gawa nagkatampuhan kami hours before it happened.
ayun, she went to Galveston by the seawall and got drunk dahil pinag-iisipan nya tampo nya sa akin. she was waiting to be sober, kaso inabot ng ulan kaya napilitan umuwi.
I blamed her dad, too for buying her a motorcycle despite naaksidente na sya himself dati sa bike nya. wala sya nasabi

at least narealize ni babae na marami kami masasaktan kung may mangyari ulit sa kanya.

[Vegeta]

kaya embududz lumamon ng gas yan gawa 5.4 liter ang piston nya na V8.
I just wanted an economy car, kaso my bro bitched about getting a full-sized truck gawa panghatak ng farm trailer to bring supplies to our pet shop.

Low RPM! Cruise at the lowest RPM your engine is comfortable with, preferably below 2000. Let momentum work for you. Once you reach this low cruising speed, pa tapik-tapik na lang sa accelerator to maintain it. Swallow your pride and let others pass you by.

Stay Away from Gas-fed vehicles. Go Diesel! :D

[ian_rex]

ok peeps, after simulating rules of the eco challenge by isuzu, here is what i have ripped-off in my tankful of diesel(DMax 3.0):

11.82 km per liter in a city driving condition (traffics, stop and go, along with some highway strecth, etc.).

a slight improvement since normally i get 10 to 10.5 km per liter in such conditions. i was expecting to get 12 km / liter but the traffic conditions becomes worser each day at NLEX.

anyway, here is what i did:

1500 rpm only (on the average-actually)
50-70 kph for the speed range
airconditioning is always operating
smooth braking, no abrupt braking.
the vehicle is in stock condition, no accessories that can cause drag or whatsoever

will keep you guys posted, i will try again this time, i haven't quite reached my objective yet.

[ian_rex]

kaya masama talaga ang may LQ e. kita mo na may nadisgrasya na naman dito. buti na lang slight lang. aside from being drunk, when driving set your other thoughts aside and concentrate on driving, be it a car, truck, or a bike, even bicycle.

[notEworthy27]

how about spoilers? how do you account for the drag it does to your rides?

[RafRaf]

ian_rex, hindi ba naglalug yung engine kapag nagshift on 1500rpm?

[kuljaw]

edzzz, matipid nga yung naka neutral habang tumatakbo ng 80 t0 90, kaso napakadelikado nun..kasi free wheel ka...al four wheels, so medyo di pantay ang control, di tulad ng engaged ang gears mo..yung 2 sa front or back..stable sila...

[kuljaw]

sync3 yung bm depende sa speed at gears mo....kung naka high gear syempre mababa na ang naka register dun sa energy control ( yung sa ibaba ng tacho) and thats in litres/100 kilometers

[ian_rex]

rafraf, not really. ok lang yun since the peak torque of 4JH1-TC is * 2000 rpm beyond that wala nang torque.

noteworthy27, spoilers accounts for the drag. unless you are reaching the speeds of 200+ kph all the time, ever wonder why the porsche has its downforce retractable? i guess it is for efficiency reasons.

[mlaconic]

I think kelangan I-revive ang topic na ito....32.++ na ang XCS!!!!!more tips guys!!!!!

[marv0083]

guys tanong lang which is efficient

reving the car faster to 2000rpm then shift then when u achieve the final gear cruise at 2krpm

or rev the car slower to 2000rpm then shift (same thing)

[pixelparadigm]

Lower revs in higher gear doesn't necessarily translate to better fuel economy. VVT-equipped engines can comfortably cruise in 2000rpms. While older engines needs to be revved more before shifting to higher gear. Cars differ in gear ratios and engine power curve, so there's a sweet spot in shifting. In my case, I'll find the best RPM to shift when I can press the gas pedal the most lightest.

noong test drive ko with my boss, talagang meron syang coffee cup full of coffee he he he

for a few seconds dinala ko sa 100 down to 40 sa isang curve then park... pasado!
