Hi all, recently purchased a 2018 colorado ZR2 with the Duramax in it! Looking forward to learning and sharing my build as it comes along! Any clubs or get together in the LA area hit me up! Nice to meet everyone!
As a fellow diesel owner, I (and others) recommend you run diesel additive at every fill up, particularly with this engine. There's the possibility that it can prolong your injector life or prevent catastrophic injector failure. I use Power Service Diesel Kleen, but mostly out of convenience as it is plentiful at the auto parts stores near me. I keep it in 5x 8oz Nalgene HDPE Wide Mouth Containers for additive in my truck and just pour one of those into the fuel tank before refilling.
Again, welcome ! And I hope you find the forums as helpful as I have.
