duramax 3.0 fuel additive
The 2021-2023 3 Duramax, as I understand block heater won’t turn on until 0 degrees Fahrenheit. I use Howes regular additive every other tank or maybe less frequently than that. A couple of OTR drivers said to use it once in a while. It’s easy to use, just 6 ounces dies a whole tank.- 1PolarBear
