If only I was close to Atlanta. DEF would be one less thing to worry with.

My truck is pre-DEF and yes. It is fabulous not having to fuss about finding DEF and filling that extra tank

So get this, I filled up the DEF and the ABS and TC light went off...

for trucks that take DEf fluid, there is a 10% silent power derate that kicks in for the engine when you fill the fuel tanks and do not top off the DEf.

I.E.> The engine maker/epa wants you to fill that DEF tank up every time you fuel, or face a silent 10% power penalty.

This is news to me. Some places I fuel don't have Def at the pump so I only get fuel. Will pay more attention in the future.

This is nothing new. It can be seen in the the ecm programming if a person knows where to look for it.

some older mentions of it...
