Ok, before you think I'm some kind of nut.... well, I keep pretty accurate fuel economy records.I use Fuelly primarily, but even prior I used to check my MPGs EVERY SINGLE TANK to track it.
Here is the Mustang Fuelly page for example....
https://www.fuelly.com/driver/sixt9coug/mustang?fu=2501302
So you see, I've got a few tanks of fuel as an example. Getting most of my tanks in the 19-21 mpg range was pretty common until a couple of weeks ago. I installed a Mach1 style front spoiler on the car.
No other changes were made at that time.
Now... I ran out the last of the 3/8 of that tank that was in there and it was normal. On the low side of normal, but not out of line for my averages.
However, on the first two full tanks of gas that I have run through, my mileage jumped to 21.9 and 22.0 mpg average. Easily.
I got 340, and 333 miles out of each of those tanks. I feel I probably had another 20 miles or so in the tank today even.
My driving style has not changed, my commute certainly has not changed, and as I said before, there were no other changes made to the car. I cannot positively contribute the change to the spoiler, but so far it's pretty compelling. However, I will keep track of it.
Anyone else running one and notice the same thing?
