Why does my diesel smoke? When your diesel is smoking that is typically (not always) unburnt fuel. That means that smoke is raw diesel coming out the tail pipe. When you're looking for fuel economy is not the way to go. We can make your pickup run more efficiently and still have all the hauling capabilities that you purchased it for.
