Is this the norm? I was averaging 16.9 mpg until the the local fill up station added winter additive to their fuel, plus I started running stansdyne performance to help with gelling. I've now dropped to 15 mpg average. Is this typical for winter driving?

Yup. Winter fuel = lower mpg.

Will plugging it in overnight help with fuel mileage, maybe warm it up faster?

I usually have it plugged in a few hours before I drive anywhere. It's garage kept too.

It's pretty cold here in Wisconsin. I've had the grill cover on too. Not sure if that affects anything.

Yep, winter fuel + the fact these trucks are pretty thirst until engine/coolant temps get up to normal operating temps ~185*

I agree though, 15MPG is still doing pretty good

Plus the fact that it takes awhile for all the gear lube and tranny to warm up. Takes more HP to move that cold truck down the road.

That grill cover makes a world of difference!! I was hunting up in Thorp (Clark county) and my truck never got warm with -6 temps. Put that cover on and I was roasting marshmallow in 15 minutes. Drove all the way down to Tennessee with it on.

I does make it warm up faster. Just wasn't sure if it affected fuel mileage.

My guess is that its due to the winter additives. I'm not deleted, but thinking about it. Just hate to lose my warranty. Been definitely tossing around the idea though since I've been regenning 1-2 times per tank. Actually getting a quote for a full delete now.

Man I was the same way and said screw it and pulled the trigger! Just wish I had done it sooner! I was regening every 200 miles and getting like 14.5-15 on the hwy. now I'm at 19.5.!! And sounds amazing!! Get ahold of Erick (Konahoss) he will hook you up!!

What year is your truck? Dealer give you a hard time about it at all or haven't they seen it yet? I'm not in an area that does emissions checks at all, but not sure if dealer would "call it in".

Mine is a 08 and I'm from Bama so no emissions here. I know the guys at the dealership pretty good but I haven't had any trouble out of the truck. I bought it with 85k miles on it and now it has 123,500. Been deleted for about 2k miles...I don't hold it to the floor all the time either because it's my only truck work/truck ha so I need it to last
