AT4 HD Ron replied to 07HD's topic in 6.6L Duramax Diesel & Allison Powertrain (L5P/MGM)I ran Rotella T4 in my 2014 and used it on the first oil change of my 2020. Just bought T6 for the 9K mile oil change - I'm sure T4 would have been fine, just seemed like I should use T6 in this expensive of a truck going forward!
I thought the same thing at first, but the usage seems to have normalized after like 6K miles. I don't think the gauge is very accurate and mine definitely was not full on delivery. After getting it topped off, usage and miles per fill up seem very similar to my 2014.
Little bit of difference in building a reliable car vs a HD pickup LOL
I think what often gets left out of these type of debates is resale. Yes, the diesel costs $10K more new...but have you looked at used diesel prices? They HOLD their value, so your used diesel is likely worth $8K+ more than the same gas truck, so the diesel cost you $2K net. I agree diesel is not the best for every application, but it is not as expensive as some gas-lovers would have you believe.
redwngr is spot on!
I added them to my 2014 Duramax. On that truck, there was something like 14 different roof wiring harnesses for all of the various options. I am sure the wiring is not just there for you to plug into. I ordered a harness that had the roof marker light option, stripped just that section of the harness out, and ran it along side my existing roof harness. Drilling and caulking was another story, but I did not have any problems in the six years I had that truck. I do know the 2015-current lights are more difficult to drill and mount as they use square holes - the 2014 and prior was simple round holes I did with a drill bit. Good luck - it is not easy and will cost you a lot more than $55!
AT4 HD Ron replied to MrGraff's topic in 6.6L Duramax Diesel & Allison Powertrain (L5P/MGM)That definitely seems odd. Mine will go 7-8,000 between oil changes per the DIC percentage.
