It's funny Michael that I'm about to ask
the same question.When I got my car the dealer
has just performed the 90k inspection,and at 93k+
I ask my mechanic to change the oil.He said that its a waste of money because the oil is too clean.
The oil,actually looks like its only been in the
engine for a month.I had him change the oil
anyway.Its too cold for me to do it esp.at this
time of the year.
Another thing,Do you have any carbon in your
exhaust tip? Mine don't have any.Should I be
happy? There must be a reason.
