Diesel Fuel Injection System Help Desk

[Dieseldude]

Hi Sir,

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

Thanks!

I don't know. I've heard people talk about this but have not seen any technical bulletin to support this claim.

Since we are a Bosch Diesel Center, Robert Bosch should have advised us on fluids which can help protect their diesel systems. So far.....none.

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? No this is not possible.

Is so ano kaya ito mga sir? I don't know. Car needs to be checked.

My concern is the downshifting na alanganin ng AT on high speeds. Is this the injection pump or the AR transmission? It could be that the throttle potentiometer needs adjustment or replacement if your car has this feature, or the transmission shift cable need adjustment.

I forgot to change the AT fluids pala.

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.

Don't touch it if it aint broke. As you mentioned, your car is running fine.

Thank you sir I have those things checked asap! You're the man.

Tuwing kilan po ako magpapa:

3. Mapapalinis ng Fuel Tank: not necessary, fuel filter will clean your fuel
4. Change ng Fuel Filter: 1 year maximum
5. Change Gear Oil: check your manual
6. Check ng Injection Pump: as needed
7. Change ng Aircon Filter; Check your owner's manual
8. Kilan po ako magpapa calibrate ng sasakayan?: as needed

Tuwing weekend ko lang naman po nagagamit sasakyan ko city drive...or uwi ng province namin sa batangas.

Hi DieselDude, Pwede po ba lagyan ng Fuel Filter Water Separator ang sasakyan ko na Innova G D4D 2006?

The original Innova filter is both filter and water separator. Of course, putting in an additional filter/separator can help.
