Hey all, just got my first diesel truck and just wanted to see what regular upkeep or maintenance is now required that I probably wasn't used to before. If anybody has a list or something of how often you need to replace certain filters or anything like that please let me know! Also I was told to get my DEF topped off every time I take it into the dealer or a shop but my DEF percent is still pretty full so should I let it run all the way down before filling it again? Any help is appreciated!
