my friend just bought a new toyota tacoma 2003 v6 2x4. the dealer reconmends break in period of 5000miles. he wants to change the oil and the filter at 1000 miles. is this wise? i know that some dealers have oil, like honda, that has hecka moly in the factory fill thus it is pretty good to run it for a while before changing the oil. he is just concerned about sludge and set up a schedule to 3k oil changes, mobil drive clean (or any cheap dino), and maybe a amsoil oil filter, maybe even baldwin (filers he is not sure of). i did a search but i havent heard much about breaking in this car. so what you guys think, would he be okay with the break in? on a side note, dealer claimed that none of their engines sludged---something to think about =) thank you guys!
