What do you guys think about oil?
Regular vs. Synthetic

syn... it flows better at lower temp..helps cold starting wear, less friction adding mileage and hp to the car..etc

depends, if u have a high mileage motor u might get leaks with synthetics b/c the chemical makeup is thinner and it will get through worn seals and gaskets. If u wanna be safe just run a good quality regular oil like mobil 1 and ull be good with that. I use mobil one performance oil. 10-30w

depends all on miles. New motor yes, old motor no.

Synthetic, unless you have a high mileage engine. the small molecular makeup will make some higher mileage engines start leaking.

mobil 1 is full synthetic, and it is good.
on my old motor, I changed to mobil 1 and gained 2 tenths in the quarter.
the new motor had regular oil for break-in, and then the mobil 1 went in.
I recently tried royal purple, and for the price, I cant notice a difference, but its only been 3 weeks though.
