Need help with eather oil or syn.

I just would like to now if I should wait untill the motor breacks in befor I use A syn. oil . I would also like to now any good idears for plugs and wires . If anyone can help just email me at [email protected] . Thanks

Which car? I ask because my WRX does not have any spark plug wires. Subaru uses a special sytem for this function, and it is very good. If you want to change plugs, there are plenty of good ones out there (but they won't make a big difference in a stock car). As far as oil goes, I waited until my first change to switch to synthetic. I don't think it matters much.

I changed my oil to Synthetic at 1000 miles, just after the initial engine break in. Non-synthetic oils are better for break-in, but after about 500 miles the car should be OK to change to synthetic. I plan on changing out the diff and transmission fluids to synthetics after about 10k mi.
