  1. I noticed this when I towed my boat about 90 miles each way. It was never increasing the temp over 210 like it does other times.
  2. Anyone experience using like no DEF? I have 1,700 miles on my 3.0 and my def is still 100% full according to the gauge.
  3. Had my 3.0 duramax for about a month. Amazing engine. I am getting consistently 30 mpg +. Tows the boat great as well!
  4. I have a 2020 Sierra SLT with the Duramax. This engine is awesome. I commute 17 miles each way (all freeway). I am consistently getting over 30mpg. I am very glad I found a diesel - it is an awesome package.
