Just want to see what engine oil and change interval everyone is using on their stock non-deleted trucks. Also want to know how many have had emissions related problems. Trying to figure out the best way to keep from having problems with the emissions parts. I know, I know delete it and don’t have to worry about it. Just trying to figure out what works and what doesn’t on the trucks that use DEF(urea). My 2018 runs great and has more power than I actually need. Only have 4.7k miles on it so throwing the warranty away is not an option. And with EPA,DEQ and whoever or whatever other agency or agent wants to do a look see or inspection, I’m just more comfortable with it like it is. So, what are y’all using and how often? Thanks
