Fuel Mileage Drop?

[Jesse@MBRP]

It's been way down since the HG install. Could the winter blend cause a 100 mile loss a tank? Seems extreme.

I have no signs of a leak. The oil doesnt smell of fuel. I havent seen any spots in the driveway or anything.

The fuel filers are 8K old and are getting replaced this weekend.

Thoughts?

It's been cold, have you been letting it idle a lot?

No excessive idling...

Did your set it back to stock and then reload the tune after the HG's? Some times it takes a while for the tune to settle back in. I had the same issue last time I changed tunes and it was right around 100 miles per tank loss.

I've gone through several tanks of fuel since then. I've played around with several tunes too.

IDK maybe just let it run through a couple tanks. If it keeps up you might just have yourself a problem

Nevermind your a little quicker on the draw then me.

It takes a couple of tanks, and your having to start all over again everytime you change the tune. Its very annoying and I dont know why it takes so long to relearn but it does.

I mean, it doesn't seem out of this world to believe that the Winter Blend could cause 3mpg drop but I would have thought it would have happened a little quicker than Jan.

It could be the fuel but I didnt notice that big of a drop with winter fuel only when I changed tunes.
