It is often wondered just how the 0w20 Dexos D engine oil is holding up in the modern 3.0 Liter Duramax Diesel. Some have purchased oil test analysis and here are the results found from the internet. These came from people sharing as well as my own. Left column is my personal truck folowed by the averages or numbers that they should read as per Blackstone. Some results even show different oils that others tried in this engine. LM2 / LZ0
Enjoy !
