Honda D15B engine [merged threads]

**flashtrader** · September 20th, 2009 08:15 AM

thanks for your reply sir, no problem with driving style, hindi ko pa hinahataw because I am trying to figure out the maximum fuel efficiency I can achieve with this. Alalay ako nagpapatakbo, pero same pa din, mababa ang mileage per km.

Mods, none yet. Ala pang budget and also I don't know where to start, pero since namention mo yung exhaust headers, large diameter tailpipes and muffler, medyo mahal ba? Malaki ba ang magiging improvent sa FC kahit matic ang tranny, hindi po na pagllakas ang engine mag iincrease din ang FC? And any reputable shops na makukuhanan and mag iinstall na won't cost me an arm and leg? I haven't tried or planning on installing these, pero if these can improve my FC then I suppose I'll go for it.

leaks maybe no, refill tube hindi pa, gas cap ok naman and air filter element is newly replaced with stock.

oh and 1500 ang D15B.

thanks and have a nice weekend

5. don't do a lot of heavy accelerating and hard stopping..
If there are no major issues with your engine and running system, this will get you the optimum fuel economy for your specific vehicle.

thanks also sir, tried and tested na ang mga methods na to. Time and time again these have been proven to improve mileage. Sa gas po ba besides sa oil, air, fuel filter ano po ba ang ibang filter.

thanks again and have a nice weekend

headers and large diameter tailpipes will "decrease" pala fuel consumption. but improve the power output of oyur engine by atleast 3hp. siguro? sorry for the confusion

if mods habol mo, expect ka ng bayolenteng consumption! bayolente talaga!

7hm/l on a bone stock 1500 cc engine? i doubt. maliban na lang kung galit sa gas pedal ang driver at hilig umistambay sa auto na bukas aircon pero nakapark lang,.

we have an a/t 1.5G vios, consumes almost 15km/l on highways(which is its everyday routine: balintawak to meycauajan nlex) and a high of 12km/l on city driving. 1 and a half week ang tinatagal ng full tank of average of 35L on an average of more or less 400km traveled. btw, loaded pa palage, mga abubut ni ermat lageng nakakalat sa auto niya(5 gallon mineral H2o), but it wont exceed a 100lbs. "sometimes"

di porket matic, malakas na sa gas,

ts said its a non vtec so i assume its an older car

older a/t cars really consumes more fuel than a newer a/t car

jdm engines also requires higher octane fuels

i agree but i assume he was reffering to at vs mt FC.

my jdm '97 civic averages 9-10km/liter. 13-14kms/li on highway. maybe sa traffic condition sa place nyo. try to travel it out of town. kung mag average ka ng more than 10km/liter then there's nothing wrong with your d15b motor.

Beside doon sa mga suggestion ng mga tsikoteer wala ka naman nasabi na problema tungkol sa sasakyan mo kundi sa fuel consumption mo . Subukan mo na patignan ang timing ng sasakyan mo kung nasa specification ng D15b. Pa double check mo lang using timing gun .Malaki rin bagay na tama ang timing ng sasakyan mo bukod sa malakas humatak titipid pa sa gasolina .Suggestion lang.
