what i did was 1st oil change at 2500. second at 5000.i plan on doing it every 3000 in the future. toyota says every 5k is good. i only do it more often because i have access to the shop. as far as oils go, the most important part of all of it is that you change your oil religiously no matter what kind you use. i use a synthetic blend oil. some people swear by synthetic, but like i said, the bottom line is frequent oil changes are key.
enjoy the new truck!
