ILSAC what ? haha, eddy will like that bet..got no idea what that is and dont care..but i am leaving on the 20's ,there is sthing called tha internet and google..so i dont care because its irrelevant to europe and its irrelevant to the question since there is another reason..imagine you go to the official service and the manual says you have to choose from 0-30 to 5-40.but the official norm is like my friend asked the 5-30 ,why?
because imagine every guy going there and want to put a diffrent oil visocsity and bust the b@lls of the service ,which would be then obligated to stock all these viscosities..so take one out and lets get rid of them..and which one is more versatile from north to the south of the earth? which is not too thin or too thick? and the winner is the 5-30...there you go!
