Mountain ranges uphills and down hills for 2weeks. Total distance travel was 522.1km and total fuel consumed for that 2week drive was 46.15liters (full tank ako sagad last 2weeks ago and then nagpa-full tank sagad uli ako today with 46.15liters). By calculation as 522.1km/46.15liters, my FC will be 11.313km/liter (mixed city, hiway, & mountain driiving).
Summary:
1st trial: hiway driving only (break-in period) - abt. 16km/liter * 26psi front & 36psi rear, petron diesel.
2nd trial: mixed hiway,city traffic medium & heavy, mountain driving - 11.87km/liter * 28psi front & 36psi rear, petron diesel.
3rd trial: mixed hiway,city traffic medium & heavy, mountain driving - 11.31km/liter * 30psi front & 36psi rear, petron diesel.
Conclusion:
My Adve 2011 GLS Sport FC is 11km/liter. (for purpose of fuel refilling at stations, I'll just use 10km/liter).
My preferred tire pressure shall be 30psi front & 36psi rear (mas mahatak Adve ko sa pressures na ito at hindi masyadong matagtag. Mas mabilis ang response ng gas pedal ko during overtakes sa ganitong pressures).
Lumalabas na: (based on my tests only)
1.) Front tire pressure is DIRECTLY proportional to FC. Meaning, "the higher the front tire pressures, the higher the fuel consumption will be". Although incremental and decimal difference lang naman halos. Anyways, I will still continue to test on the next 2 weeks. The more tests, the better.
2.) Ideal tire pressures are 26psi & 36psi. Now i know kung bakit ito ang prescribed pressures ng manual. The problem lang dito is mukhang laging FLAT ang front tires and as the tires grow OLD, lalong magmumukhang flat ito sa 26psi. The older the tire goes, the more pressure should be used in order to counter the rubbers deteriorating elastic properties. Kailangan ma-maintain ang tires sa shape na wala itong masyadong BILBIL.
