yun yata yung kung magpatakbo ka parang si rossi
part synthetic?
hmmm when breaking in an engine dapat standard oil lang para mag wear ang bore ng normal (breakin process stage)
if you will use fully synthetic or part synthetic that means less wear (breakin process is less)
me for newly bores,
i use yamalube for the first 5000kms on vixion kit (500kms &1000kms change oil) +
hard breakin = then fully synthetic na after...
so 1000kms odometer + part synthetic oil = kulang pa breakin process
OR
talagang minalas lang..
ganyan talaga pag mag mods

wish wish lang hehehe
