Maybe I just didn't use enough of em on the Heep.....

Jeff, any noticeable increase/decrease of wind noise? Stability changes? Anything blowing around?

I dont know that I have noticed any stability changes, but Ill get a better feel for that after a long hwy 95 trip tomorrow. It may seem a little more stable, but I may just be thinking that based on what Ive read - the power of suggestion you know. Really hard to say. I havnt noticed any less wind noise either - but the radio is usually on too. I will listen for it on said hwy 95 trip.

Where do you live on 95?

jeffreymccoy 10-21-2007 05:11 PM
Raleigh, NC area...traveling up to Baltimore

Ah, you're way down from me then, I'm from jersey.

Man, I put 5, just 5 white ones on a white Jeep Liberty, and couldn't bite the bullet and mount them everywhere...I have to applaud you for diving in like that.

Wow! Great results for the ford truck!

Hopefully your results continue to show an increase in MPG to show this is more than a one-time event. Good luck with your better MPG quest!

Maybe I'll look into some of these for the VX. I'm sure they can't hurt!

I often travel the bypass portion of my test route. Two more trips out and back along this stretch showed 25.x mpg. So it has been repeated a few times. Ill update the group with more after the road trip.

Appears to be a solid 2 mpg gain (7-9% increase).... It was also pretty cool to "see" them working. I drove under a falling leaf. It would normally have hit my windshield and bounced over. Today, I saw it falling and then get rushed up over the windshield without ever hitting it, so it would appear that the tabs on the hood are indeed directing airflow over the windshield to some extent. Granted, this was one lousy leaf... it will be interesting to see if this trend continues (lots of falling leaves this time of year), and if I have the same experience noted by the other guy - a cleaner windshield...:thumbup:

Cheers

Now that's what I call just diving in! Wondering where you got the idea for using the tabs on the hood?
