What oil?

just my personal opinion but i find that if you use synthetic oil and your car leaks any oil the synthetic leaks out much faster than conventional oil. If you have a new motor and run synthetic oil from the beginning then i believe in it but the other thing is you cant break in an engine on synthetic oil the manufacturers dont reccomend it so if you have an older /6 and it leaks a little oil like most do i would just run conventional oil myself but again that is my personal opinion.
