看你的什么机器,如果TUBRO的话,必须要用SYN OIL
Doesn't matter, depends on what are you doing with the car. If you are driving hard all day everyday then it is wise to use synthetic oil, if you are just driving a low hp turbo car, just make sure you do your regular maintenance.
no matter you drive your car hard or soft,it have to use syn oil,or you get fucked up in the furture. the problem will come out with oll sludge around 100k mk,especially vw and audi.trust,you will cry once you got that problem.
check out your dealer ship and find out.
