So I went to Seattle & back today. Maybe not the ideal day as the weather was terrible. It was pouring rain almost the entire time up & back with a lot of water on I-5. I also had a slight tailwind on the way north but it picked up in the afternoon when coming home & I had a very strong headwind southbound. The outside temps were from 37F-48F & my coolant temp never moved above normal.
That being said the results of the grill block speaks for itself. I was traveling between 55-70 mph with a small amount of city driving getting to & from the Seattle office. I've had several times when my computed actual MPG was higher than my display & this was one of those times. I knew that I was getting great MPG as I traveled 343.6 miles & I was still above 1/4 of gas.
This was a sample of the conditions as I was headed southbound back to Portland.
This was my display average MPG which was pretty good anyway for the amount of rain & wind that I drove through.
This pic shows the trip meter as I stopped to fill-up.
Here is what it took to fill-up. I used the same station, pump & filled to 1 click after it stopped like I always do.
So the bottom line......
343.6 miles/8.745 gallons = 39.29 MPG
I've never come close to MPG in conditions like these. I would be happy with 32-34 MPG so this proved a great benefit.
Now to design one for the inside.
