Well, they wont pick it up on the curb down here...
Gotta take it to someplace like Napa or whatever.
Anyway, if you are using dino oils, then i dont care what the manufacturer or oil companies say...change it every 3k. There is absolutely no reason not too, and way too many reasons that you should. Now synthetic on the other hand....thats another story. Why run synthetic if you change your oil so often anyway? One of the larger benefits of synthetic is that you get a longer oil change interval. I dont have much first hand experience with the stuff, but the earliest i could see myself changing synth is every 5k. It is engineered to last forever. Its not designed to be changed every three. You might not even be getting the best lubrication and protection if you change it that often, since last i heard, synthetics hafta sort of "break in" anyway. The long and short of it.... dino oils = 3k religious changes, synthetic = 5k+...the exact timing doesn't matter all that much since it will go for much longer. Would probably be safe changing it every 10k or so even...
