Hi folks. We purchased our first diesel truck in February. A 2014 Sierra 3500 HD. I've been reading a lot about diesel trucks as it pertains to pulling a trailer, but what I haven't found is info...
Besides straight ULSD, there is bio diesel of various %, such as 5,10,20% etc.Be aware of what % of bio diesel your truck is made for. In addition, in colder areas of the country, some diesel has non gelling additives certain times of the year.
