So you are telling us that all the 18 wheeler over the road trucks meet these stringent Diesel Standards? Somehow, I doubt that. . . . .
They may be exempt from them, however they are not exempt from needing to be made to run properly on ULSD, which means that they will also be using CJ-4 oils.
Also, it's all about mpg with the truckers, and when a rig is belching black smoke it's not getting the best mpg it could...meaning it's costing money.
Check out the brand new semi's going down the road...their exhaust is clear just like a cars. That's how it'll be going forward...
