    Hello all, I never really found out what was going on with the truck. It never seemed down on power, or felt like it had ever stumbled under load. I chalk it up to a bad batch (or two) of gasoline I picked up during my travels, but I'm not totally sure.

    It's always gotten decent fuel mileage unloaded. Hell, I was able to make it from where I live in Wisconsin down to Louisville, KY on a single tank of fuel... all while hitting stop and go traffic in Chicago and Indianapolis. I try to use quality gasoline when I fill up (Top Tier)... maybe got a bad tank of gas sometime in the past.

    3 of the plugs came out of the driver's side bank (CYL 1,3,5) and the last came out of the passenger side bank (CYL 6). I don't run the truck particularly hard. It's a tow pig in the summer time for my boat, but that's only a couple times a month... and it's only about 5,000 pounds fully loaded so I'd hardly say the truck is being worked hard. I forgot to mention in my original post that the truck is completely stock, minus a muffler change. I have a buddy who is a tech for a local GM dealer, I may have him take a look at things sometime soon.

    These are the OE Delco 41-110 plugs that were in the truck since new, and as far as I know they are Iridium plugs. I was just a little shocked to see something like that with low miles.

    Hey guys. Out of curiosity the other day, I replaced the plugs on my 2015 6.0. It seemed like the truck would slightly misfire on a cold start for a few seconds and then clear up, hence my curiosity. Truck has 47,300 miles on it at the moment. I found that 4 out of the 8 plugs i pulled had the electrodes burned off. Any reasons you can think of why this would happen? I live in Wisconsin and it does sit outside in the winter time without a block heater, so the only thing i can think of is excessive idle time. Thanks for the help!

    Here's my truck! I've had it almost a year now. I couldn't be happier! Only mod so far is changing the trash can muffler out for an Aero Turbine 3535XL. Plenty more things I want to do though!
