Thanks for the quick reply dieseldude!

Check/replace air filter.

replaced already

Check timing.

it seems to be in timing, but i'll have it re-checked

Check for sticking brakes.

checked as well. although i forgot to jack up the tires and check the retarder if it's really functioning properly.

When did this problem start?

5 months ago when the truck continuously ran out of fuel. at first i just thought the driver was doing "paihi"

Has any previous work been done to this truck?

i had the injectors sent to a local (malolos city) calibration shop. nothing changed, still the same consumption.

How many rear axles, 2 or 3?

tri-axle

What is the average weight of your load?

26 tons
