The Valvoline TCW-3 should be fine to use, but it DOES contain a higher percentage of additives and dispersants than the ones on the list. Most TCW-3 rated oils should be fine to use but the ones on the list are those that are made up of mostly lubricating oil and only a small percentage of dispersant additives.
As for my previous post regarding the ULSD and the 6.7L.....streetrodder......I think I read your post a bit too fast. I thought you said "New Mexico" NOT "Mexico". I would be very wary of fueling anywhere OUTSIDE the U.S. Considering the problems we're facing right here in the states with cross-drops (gasoline in diesel tanks), water in fuel, and just plain inconsistent fuel quality at many fuel stations, I'd think refueling in Mexico would be equivalent to playing Russian roulette with your brand new and very fuel sensitive engine. The extra fuel tank to guarantee fresh ULSD would pretty much be priceless. Sorry about the mis-read info.
