When to go Mobil 1

[BigED]

Is your second oil change? (6000 miles) to early to go mobile 1? If not, what weight oil do you guys use? Also, what will this improve in my car?

change normal at 1000, then synthetic at about 2500. worked for me. seems to make the car a little smoother, i think synthetic works better

You should change to synthetic as soon as the break in period is over.

Where did you all get this info from? If this is true then why do some cars come with Mobil 1 in them from the factory?

You should always run the oil that is included in the car through the break in period. If synthetic is included, then there is no problem, but very few cars come with synth, so it's not often an issue.
