New Roof Increase Gas Mileage by 43%

I get a lot better mileage when I remember to crank the TV antenna down before getting under way. :R

True story. A fellow Grad Student and I built a scale model of a Clipper Ship ("Herald In The Morning.") to test in the MIT Tow Tank... long story.

Bottom line, the technician operating the tank towing mechanism noted that there was less drag when returning the model to the head of the tank for the next run.

It actually had better performance going astern than ahead! (It had no rudder or other appendages.)

PS We did not win The Great MIT Boat Race of 1975 anyway.

I had them spray nitrogen on our roof while I was getting nitrogen aired into the tires....Mileage went from 11 to over 20.

You may be joking but... You'd be amazed at how much damage a coat of Wax can do to Big Oil's profits

Or if you like GOOD for your MPG.

The additional comments were pretty funny.....agree the OP should have waited longer and let things play out.

I've only had the new roof for 2 days so have not been able to determine if there is any insulation benefit. The shop owner told me I will notice an improvement in insulation. I'll learn more as we camp in the coming months.

How long it takeya to hose off the mudslide?

In reality, I didn't find that all that hard to believe.
I got 1/2 that much just doing a wash job one time.
