you should fallow you owners manuel for the specifics on the intervals. i have an 03 and change it about every 10 k. but i only use synthetic. if you use standard dyno oil the interval should be shorter. since it is about 10 k you engine is almost broken in so some sugest you run the dyno since the synthetic is to slick for break in. i personally changed the dyno for synthetic after 4k. so far no issues after 54k. i run valvoline blue synthetic. and please dont open up the oil can of worms and ask whick one is best. believe me every one has their opinion there! by the by an oil change at the local valvoline shop runs a hundred bucks (another reason i do it at 10k intervals not every 5k)
