I really dont like the oil casa use for my 1K PMS. Its a HGMO semi synthetic. Feeling ko mas umingay and mas lumakas consumption. from 14 km/l to 13 km/l manual computation, city driving. Also, when i drive at slex, i reset the gauge to measure the consumption, before i can get 4.6 L/100 KM, now its 5.6 L/100 KM. =( Next time i'll bring my own Oil.
