I have a new Cat C9 with the allison transmission and I was wondering what is the best way to break it in? When would you do the first oil change and how often after the 1st one? I have many different opinions but mainly from dealerships. I have been told everything from every 11,000 miles up to 24,000 miles. I would like to maintain this engine so that it has the best chance to make it to 500,000+ without major work. Is that reasonable? One last question. Does anyone have experience using bypass filters (Gulf Coast Filters)? It sounds really good but does it work?
Thanks!
Thanks!
