Lucas Oil Fuel Additive

Is anyone using the Lucas Oil fuel treatment in their 2008 LMM trucks? If so how does it perform?

You mean the Lucas Fuel treatment. Not the lucas oil treatment in your fuel.. Right?

Im not sure about the LMM but in my trucks owners manual it says NOT to use any fuel additive? I have no clue why though

Anyways, I use the fuel treatment and it works pretty good in my LBZ. I use it ever few tanks to help lube the fuel system etc.

No. I dont use any additive in my '08 LMM. I used to be a big time additive junkie on my other Toyota and Ford trucks.

It seems that GM went to great lengths to put out info about not adding anything to the diesel fuel on the LMM's.

However, the operator's manual does say you can add some cetane booster for absolute fridgidly cold weather.
