I personally changed to synthetic at 7500 miles. Only reason I waited that long is because I got my first oil change done at the dealer.There are a lot of theories on the net about when to switch over synthetic oil. Some say not before 10K, some say not before 20K, and some say you can do it whenever. I'm approaching 1,500 miles and regardless, I will be changing my oil.
So, what's everyone running in their engine?
Should I go synthetic now or later?
I would use Mobil 1 Fuel Economy.
I say put it in now. As far as using Mobil 1 I think you can save yourself a few bucks and go with a different brand. Valvoline is cheaper and proven to work better. If you want the best get Amsoil or Eneos oil.
