Mini i find yuh real bussing style wid ure mileage...... the answer ppl is this
The 3-stage VTEC D15B has other technological advances that the plain non-VTEC D15B and indeed many other Honda engines doesn't have. The 3-stage VTEC D15B has the ability to operate in lean-burn mode. Lean-burn mode indicates the engine is running at a super lean air/fuel ratio of around 20:1 !! Normal engines would probably have detonated itself to pieces way before getting anywhere near this ratio but the 3-stage VTEC D15B exploits the 12V mode to acheive this. In 12V lean-burn mode, only 1 intake valve opens during the intake stroke and this causes the air to swirl into the combustion chamber. This swirling promotes a very complete mixing of the air/fuel mixture and with other design innovations, Honda is able to run the 3-stage VTEC D15B at ~20:1 a/f ratio under ideal conditions (very light throttle, level road, etc). Lean-burn mode on the Civic VTi and Civic Ferio Vi are indicated by the lighting up of a green LED on the dashboard with the word "econo" on it. Actually, the 3-stage VTEC D15B is the only Civic engine in Honda's history so far to have this LED feature. For the person who values economy, it is a fantastic way to monitor fuel consumption. Everytime the ECONO led lights up, it means lean-burn mode and the engine is running at ~20:1 a/f ratio. Sustain this and fuel economy will approach 28km/l ! With careful and sensible driving styles, it is often possible to maintain this mode for a surprisingly large part of an ordinary journey. The beauty is that even if there is a need to overtake the car in front, lean-burn mode can be re-entered again almost immediately after the manuveure
so if yuh want ah fun car dat easy on the gas get ah HONDA (buh the VTi/Vi models). I like the technology behind it, buh my heart lies wid mitsu so the only way i getting dat is wid ah 1.3 or CNG/LPG and daz minus the power
(over 100lbs in recover equipment and another 100lbs of in car audio doesn't help much..)
. i using the blasted super replacement and i geting ~380km now on a full tank costing $90-95.
