wala bang nakalagay dun sa manual na yun yung recommended ng NMPI or UMC?
kasi most sites kasi na nakikita ko laging ang sinasabi is dapat daw always refer with the manual kasi daw yung manufacturer ang magdedecide kung ano yung approve for local conditions....like sa 4m41 ang recommended ng MMPC is 15w40...pero ang punto ko nalang dito kasi is what recommended may not always be the best hehe...which is proven ko naman kasi mag 60k kms na ko maganda parin ang andar...
with regards with the oil naman...I think yung Y being 30 is to thin na...kasi like yung sa mobil1 na 5w40 may characteristic parin daw yun ng 15w40 but a better blend so pwede parin magamit dun sa mga engine na may requirement talaga ng 15w40... kasi AFAIK meron pa din mga engine na strictly required ang 15w40 na grade...
dun naman sa Motul being ester based, actually lately ko lang rin nalaman na ester based ang motul, dati kasi yan lang yung nakita kong Crdi specific so syempre name palang nakaka attract na so yun na binili ko hehe...
but technically, parang contradicting yun sa pagiging synthetic diba? kasi Ester is organic based tapos ilele-label ng fully synthetic? IMO parang it destroys the whole idea of the synthetic oil..kahit na ba kasi sabihin na pinuno ng additives yan to reach the standard of fully synthetic, fact is theres still the organic part of it and it is in everyones knowledge that it can degrade at a much faster time...hehe medyo nalalabuan na talaga ako eh hehe...to think that I've been using it for the past 3 years....kaya napapaisip na din akong mag switch ng brand...
sana may petroleum engineer dito sa tsikot na pwedeng mapagtanungan regarding this...
BTW Hanggang ngayun ba meron pa rin nun sa blade? hehe kung ganun ang presyo kahit 7 to 8k kms lang pwede na change oil agad hehe
