It is still an internal combustion engine and I don't think using regular vs. synthetic will void a warranty. (How would they know the difference really?) It is all a matter of the level of care you want to put into the car while you own it. If you don't mind spending $35 alone for oil and a filter for synthetic but want the better lubrication, use it. If you aren't as picky and don't want to spend the money, run regular oil.
For example, I religiously change the oil in my civic every 3000 miles and use regular oil. On the RB motor that I just rebuilt, I broke it in with regular and have now switched to synthetic.
Its up to you.
