hi all, i will be going for my 3rd servicing soon. my previous 2 servicing, they used mineral oil instead of Synthetic. my friend told me that u can actually requested for Synthetic for the 2nd servicing.
from my log card, i noticed that it stated "using Synthetic engine oil". my friend told me that i have to instruct them to wash throughtly to remove the mineral oil as it is normally very "dirty", before pouring the Synthetic oil. isit true that I have to inform the guys from TCM if not they will just ignore n not wash??
