I'm just stating what happened to me....I'm not stating what brand of oil to use or what weight. It's close to 90 here in NJ and 70% dew points...hot and it gets in the teens here in the winter.

My point is if your truck starts to rattle on start up and it's not the timing chain try and use BMW 5-30 syntech and a factory filter and see if it helps or fixes it. It took about a week like I said and now for 3 weeks so far no more rattling on start up at all.
