I saw a YouTube video where the guy shows the DEF injector after using the platinum. He claims prior to using it there were white crystals forming around the end and now the injector stays clean.
Just reporting not making a claim.
Just took delivery of my 2023 Yukon XL with the 3.0L LM2.
Only took 9 Months to get..... Worth the wait!
Loving it so far. Great ride and exceptional mileage.
Added a Bank's I-Dash so far. More mod's coming soon.
