Mileage: bursting your bubble

[Machine]

After 2 tanks with the tonneau, I am 2 tenths lower in mileage which I can attribute to the cold weather and slowness to upshift when it is cold.

Just a caution...don't spend the money that you were planning on saving until you have proven that you actually are getting better mileage.

I made sure to only check the mileage occasionally and not leave it displayed to assure that I didn't change my driving habits.

I agree. This has got to be the biggest mpg myth out there. I have a Vanish tonneau cover and have not noticed any mpg gains. And if there are any, they aren't noticable on my ScangaugeII. I do love that my cargo stays dry, but then again, so do the insects and spiders that get in there

LOL... never bye a tonneau cover just to save gas. They can help in certain situations. Very specific conditions are needed for any improvement such as specific speeds, etc. I could even see it costing you if its a very heavy fiberglass model.

The general idea is that a cover protects whats in your bed and if it saves you on some fuel then thats a bonus.

Never had spiders in my bed that I noticed though...

Well I get about 2 miles per gallon less with the "winter gas formulation" so perhaps you gained and just dont know it yet.
