Fuel Consumption is 5km/liter

**bail** · September 22nd, 2017 09:43 PM

Na observe ko after changing my oil from 20w50 to 10w40 and also from bosch platinum spark plugs to OEM spark plugs, fuel consumption ko naging 5km/liter na lang. bago din naman ang air filter. car is 1997 corolla 1.6 gli with 123k mileage. Ano kaya ang problem?

Check tire pressure..

Aircon compressor bearing/ pulley bearing

Rear brakes/ Handbrake cable

Check for fuel leaks

Check- aircon aux fan/and condenser...

Check your car aircon for high pressure

And Balik mo lahat ng ginagawa or pinalitan mo dati...like oil.. spark plus etx.

kung humina hatak ng makina sir, possible nabawasan compression dahil sa mas manipis na oil na ginamit kaya lumakas fuel consumption.

maybe its the other way around. baka gumanda hatak ng makina since manipis oil na ginamit kaya naging mas aggressive driving style ni TS at tumaas fc

seriously, TS just get back to the old oil and spark plugs. using thinner viscosity oil may not be that good to a 20 year old engine seals..

Long shot, - sparks bro.

One of our rides was doing 8km/L for a long time.

I changed spark plugs.. went down to 7Km/L

Check mo dipstick kung nababawasan ng langis or check mo tambutso kung meron na kaunting usok lali na pag dinidiinan yung gas pedal. Pag positive pareho ang dahilan nyan ay yung paggamit mo ng manipis na langis. Dahil medyo luma na, maluwag na yung mga piston ring at sumusuot na yung langis sa compression chamber. Kasama na sya nasusunog dun at hindi na tuloy maganda and air-fuel mixture kaya mababa na efficiency ng makina.
