As long as po na pasok dun sa SAE viscosity, proper fuel type used + the "supplementary type certificate", (reciprocating)no problem po...
pero sa land vehicles, same concept, yung lang po, hindi ganoon katibay during ops, lalo sa temp. not unless kung may mga certain mods...applicable pa rin....(di allowed dahil sa world politics)...hehehe
