Thanks for your helpful input Elle! I'll be watching my mileage to see
if my mileage is reduced. I'll also have to look into perhaps using a
synthetic. Although, I'm a bit hesitant because synths cost a lot more
than regular oil, although the trade off is that you don't have to
change as often.

I have a question though, how often is it necessary to change the oil
on newer cars? From my research it looks like there are two schools of
thought. There's the old school where after your car is several years
old you need to change oil every 3,000 miles.

Then there's the new school of thought where auto manufacturers (due to
better equipment on cars nowadays) say that you only need to change the
oil every 7,000 or even 10,000 miles.

Who is right?
