Just turned 2000 miles in my Z and decided to change the oil. What weight should i use...and should i use synthetic?

Thanks

Mobile 1 Synthetic after 3nd oil change.

1st was done at 1k miles, second was done at 3k

3rd just done at 7k miles with Mobile 1 Synthetic and that's not open for any syn Vs. non Syn debates it's just a factoid of personal preference.

what weight did you use? and why would someone use synthetic over regular, or visa versa, ie "whats the difference?"

Whatever the manual recommended I think it was 10-30, maybe 5-30?

Synth just seems to take longer to break down it's viscosity and how that could be a bad thing is something I never bought in to.

i use 5-30 Mobil 1 synthetic all the way 1,000 miles then 3,613 miles for all the above reasons

conventional oil 5W30 at 500, 1500,2500 and then

Mobil 1 supersyn at 5000. every 4k miles thereafter. Engine runs very well.
