Before and After chin spoiler MPG

@jerkwithkeyboard

I stand corrected! LOL

Honestly, I didn't try hard to attach it.

Come on, man! You gotta admit, it looks good without it!

 

I'm surprised they didn't charge you 50 bucks to take that hideous thing off your hands.

 

There goes the resale value on that chin spoiler. Should have hit it with that 303 first.

 

LMFAO

 

I guess it depends on the regional package. I have the "Predator" package for my Sport which came Duratracs 16s...

 

Sounds like you did good my friend, an extra 50 in the truck fund is always a good thing!

 

I don't lol. I tongue in cheek.

 

That's the baseline before the 80mph test that was added in 2008.

 

I’m back with my typical PSA—it does make a slight difference in fuel economy at highway speeds and the reason different trim levels have similar window sticker scores is because in the USA the EPA batches like vehicles together and doesn't even test every trim type.

 

Lol. My SR5 is performative too, then.

 

When you fill up you put 22 gallons in your tank?

 

18-19 gal usually. 310-320 miles.

 

Yep i was laughing at that also.....
must be letting the extra 1 Gal hit the ground because it only has 21 Gal tank (fuel miles will shows ZERO left with about 1-1/2 gal left in tank) so 18ish if you fill when the light turns on.

 

Average for the high speed test is 48.4 mph.

Good chart. I forgot about the four stops, really brings the average down.

 

Oh, heck no!

I have filled up at 1/2 tank since I learned that waiting until 1/4 tank was bloody expensive! (It took one occasion to learn this lesson)

I just mentioned 22GL as a reference to be divided by the total miles per tankful.

 

Old thread here but real world results from chin spoiler on and off. These numbers are figured by calculator not the onboard mpg reading even though most times it is pretty close in my truck. 1500 miles with chin spoiler on averaged 20.66 mpg. 1500 miles with chin spoiler off averaged 20.28 mpg. The difference is 0.38 mpg so not much at all. I decided to leave the chin spoiler on but not because of mpg. I noticed with the chin spoiler off for 1500 miles that the truck seemed to wonder more almost like I was driving on a windy day. This was especially noticable around 18 wheelers at highway speeds. I would have to fight the steering wheel a little more to maintain a straight line. With the chin spoiler on, its almost like it helps direct the air around and away from the truck. So, for that fact alone, having the chin spoiler on is worth it to me and not for the mpg difference. Hope this helps someone because I got tired of reading opinions that were mostly for looks and decided to test it for myself.

 

Mine is back on for the exact same reason. It’s a bit more stable and it may be a tad quieter. Less wind noise. It works for me, I really don’t care what others’ think.
