Since when do they require hazmat??...I even dropped mine several months ago and they haven't said anything...
Are you at 100I yet? If you are I would think about it. That mpg seems like your losing fuel somewhere.
36000 miles on the truck. Picked it up brand new. The only thing I've had done is a fuel filter change and a kw software update. The fuel filter was clogged solid at 34000 miles.
Wow. That is weird. Why so clogged so fast. What fuel are you buying? It seems so weird about that low of mpg.
I typically purchase at loves but I've made a few exceptions for really cheap fuel. The truck does sometimes make a popping sound when I let off the accelerator even when the engine brake is off...exhaust leak maybe?
Could be. You should get at min 7mpg even driving like a crazy person. That seems like something wrong on the truck.
Oops, repost by mistake. Nevermind, not use to posting by cellphone, now that I'm on my laptop....I don't DRIVE like a crazy person. I told the shop about my low mpg and they told me that it was probably the way I was driving which sounded CRAZY to me, especially after reading other people's experiences with the same truck.
