A new personal best! 45.59 MPG!!!

[pole120]

I've been making some subtle modifications, almost all aesthetic, to my festiva over the last 9 months i've had it.....in those 9 months i've had a best of 41.87 MPG.

Well, I recently installed the throttle body half of an Aspire intake tube to help eliminate some restrictions as well as clean things up by removing the resonator box on the valve cover. At the same tie i bumper my tire pressures up just a hair as well as began occasionally shutting the car off at light that i know to be long on my daily commute to work....and the result this far, a new best of 45.59 MPG.

This is with the dirtiest air filter i've ever seen mind you, and I just installed a new one before filling the tank so hopefully numbers improve more still.

My next step, after a couple weeks of driving with the new filter is to clock the VAF as described by Dave G and see just how much it will help if at all.

I've had an Excel spreadsheet set up since i bought the car that automatically calculates fuel cost saving vs driving my SVT daily and today alone i saved $26.18 in gas.

Since it's first full-up on 9/9/06, I've put 17,304 miles on her, mostly trouble free, and have saved to date a total of $817.52 in gas. Vehicle purchase price: $500

You can log your gas usage at www.gassavers.org and it'll graph it etc. You've got aways to go to catch up with me :wink: I've averaged almost 53 mpg for my last 3 tanks.........

Do you have pix of how you used the aspire intake tube? i thought i remember looking at that, i thought it wouldnt work

Way cool. Would love to hear about the Aspire mod. I'm stuck at at 41.5 and could use another tweak to get me nearer my goal of 46.

Great job! How long is you daily drive. What are the road conditions and how fast are you averaging. I only get 35@65mph straight interstate. 4 speed :roll: Now go update your web site so we can see what mods you have done

[quaddawg]

Shoot, I get 36 at 70-75 interstate and city combined, WITH A B6!

If you do a LOT of interstate, I hear you can get a few tenths by removing your side mirrors and more by rolling your windows up and just using the vents...

Hypermiling is cool... but not my cup of tea..

Keep at it, I still think its cool....

My commute is just under 30 miles and consists of a bout 2/3 back roads and 1/3 highway. Speed limits vary on the back roads from 25-45, but I'm usually doing around 35-60...so I'm not driving like a grandpa to get better MPG, i'm basically just shutting the car off at opportune times where i can coast and maintain speed, am coating to a red light, or sitting at a long light. Keep in mind that I only shut the car off a few times before i recorded this mileage. This tank I'm being a fair amount more diligent about it but i'm by no means the kind of person that does this as often as possible because I think it's fun. I'm doing it every so often for the sake of fuel economy and to see just how effective it will be.

As far as pictures, I'll try and get some taken ASAP. The aspire intake tube is literally a 15 minute job with a ratchet, screw driver and a hacksaw.

[deathegg]

have you taken it out for a long highway trip just to see highway mileage?

[pole120]

usually about 42 strait highway at 75mph...

[stefan]

any pix of that intake?

[pole120]

I took a few the other day, I'll try and get them uploaded and posted tonight.
