sir salamat po sa enlightenment, so i guess when i do my next change i will not be looking for oil with W on it.., sir what do you suggest then the best for my ride an A/T Diesel Turbo Engine (X-wind) magpapalit na po kasi ako ng langis. First ride ko po ito, and the last change oil was made sa Park & Fly and i assume they filled it up with just a regular oil kasi mura lang po eh, hindi ko namonitor kasi iniwan ko lang sa kanila.

Thanks again for your advise...more power sir.
