? I like to run #2 in my cummins 6b. But is it worth it?
It's my understanding that you can't run it in a tier II motor. The " dirty fuel " wipes out injectors & pumps because it's designed to run on ULSD. It also stinks when you burn it. If I get straight ULSD the exhaust burns clean. If the truck had some leftover #2 oil in it and it's mixed with the ULSD, you can smell it in the exhaust immediately.
Tier 2 compliant engine
We're on tier 3 currently
Tier 4 starts in 2014
The big companies will not fuel you up with #2 (because it's all illegal and stuff)
