The best way to determine any car's FC is from full tank to full tank and noting from your odometer or tripmeter how far you drove until you filled up the 2nd time. Then divide the kilometers by the number of liters of fuel.

The fuel gauge is not that accurate.

Hi got another question what are the things that I need to have checked or tested in case I' m having fc issue. Mine is only averaging 7km/l w/c I believe cosumes too much fuel for a 1.3 carb engine. I already have it tuned up for fuel economy at Mitsubishi Casa at Dasma few months ago it seemed to have improved but now it went back to 7km per liter. I'm not sure if "pizza pies" have bad fc or if it's just mine.

FC is really something that depends on many factors.

One factor is the lightness or heaviness of the traffic in your weekly route. Another is your driving habits (do you like to accelerate quickly or do sudden braking, etc). These does not even have to do anything with your car.

As for your car:
-engine condition - ignition timing, sparkplug condition, electrical system condition, cylinder compression
-engine carb - is the carb clean and jets in good condition? Have you checked for the jets being eroded by E10 gasoline?
-engine accessories - are the belts okay or too tight? Are the bearings still fine or do they need replacement? Does the alternator and compressor rotate easily?
-suspension/wheels - is your wheels aligned and have the correct camber? Do you have correct air pressure in all tires? Are you using wide tires or narrow tires?
-car interior - do you carry excess heavy baggage in your car? reducing weight will increase fuel efficiency.

Traffic & heavy baggage is not an issue in my case I mean there's not much congestion in my route & been following fuel economy tips. I guess the next thing to do is to have my car checked as mention above. Thnx for being informative I'm learning a lot here =)

neyson, I think 7 k/ltr is too much for your 1.3L Hindi kaya sira ang carb mo? If you followed the advise of GH and fc is still a problem, sound like a bad carb. The idea of filling up a tank, travelling for a distance then filling up again, dividing km travelled by
liters used is the cheapest way to determine fc. Its not accurate compared to flowmeters, though. Our 98 KIA Pride has a fc of 20-25k/ltr(before 13k/ltr)

This is your lucky day. If you pass near our place, I'll install our device absolutely free, provided you tell me at least a week before coming. Kung may barkada kang dadaan dito, ibibigay ko na lang sa kanya, since you are too far away from our place. Yong NUVITRON lang which could save you 20-30%. You should fix your car's fc first, to at least 10-12K/ltr long drive; otherwise, your fc will be reduced pero may problema pa sa car mo, baka lalong lumala. Please read our blog: nuvisys.blogspot.com I'll be waiting for your call if you are interested. Thank you
