Sir, pwede ba magbago ang fuel consumption mo kapag nagpalit ka ng timing belt? 2C engine, 65k km, para kasing lumakas consumption after magchange ng timing belt.

Walang effect sa fuel consumption ang pagpalit ng timing belt.

Pwede magkaroon ng effect kung nawala sa timing ang injection pump nung magpalit ng belt.

Pwede ba ito sir ma check na hindi babaklasin buong harap? Or any other symptoms na nawala sa timing yung injection pump?

Pwede ba ito sir ma check na hindi babaklasin buong harap? Sa palagay ko pwde.

Or any other symptoms na nawala sa timing yung injection pump? White or black smoke, sometimes knocking sound.

sir, my car is a crosswind XUV AT, 2005. my concern really is its higher FC. some friends who owned the same car claims to have their FC around 10-12km/l (city drive) while mine is only within the 8-9km/l range. i had the injectors cleaned and balanced at a calibration shop near my place. however, nothing changed with my FC. by the way, it's a well-maintained car. anong pwede gawin dito para tumipid naman ng kahit kunti? thanks so much.

Sir, malaking factor din ang driving style sa fuel consumption at tire pressure, tire size, ilan ang laging sakay, pati traffic conditions

Hi Sir,

Is there any truth in putting kerosene in your diesel fuel tank to clean your fuel system?

Thanks!

Hi sir DD, i have a pajero DI-D 3.2 A/T 2003 model ride. It has 183k on it but seems to be running well naman. Considering its age and mileage, i think its about time to have its fuel injectors serviced. Can you give me a quotation via pm more or less how much will it cost me. I dont want to try other diesel service centers as i wanted to deal with you guys who are experts in this kind of field. Thanks in advance.

Guys I have a 2008 Isuzu Sportivo AT. The following was recently done to my ride:
1. Changed Oil.
2. Change fuel and oil filters.
3. Cleaned air filter.
4. Blanked EGR (This removed the black smoke).

On our recent trip to Naga City via south road I experienced the following:
1. Maingay na makita.
2. Very slow acceleration (Feels like stuck to the 1st gear).
3. High fuel consumption.
4. At 80-90kph it feels like from the 4th gear it automatically gears down to 3rd while accelerating.

On our way back eto naman ang nangyari:
1. Pumino tunog ng makina hindi na maingay.
2. Overtaking power was restored.
3. Fuel consumption improved. We managed to consume a little less than 1 full tank of diesel.

Question: Is it possible that a broken part was suddenly fixed? Is so ano kaya ito mga sir? My concern is the downshifting na alanganin ng AT on high speeds. Is this the injection pump or the AR transmission? I forgot to change the AT fluids pala.

Replace air and fuel filters. Service injection pump if there is no improvement after the filter change.
