    I'm new here too and I have a Honda Pilot (well, it's my wife daily ride). Don't have much advice but I did buy a ScanGauge-II for the Pilot. The SG doesn't work very well for us. I am still trying to calibrate. The variable cylinder (ECO on the dash) messes SG up a little too.

    One thing I'd like to experiment with is some aero-mods. I don't know much about aerodynamics but I would think the Pilot is one of the worst (.36 drag coefficient).

    So far, I'm barely able to achieve EPA MPG using hypermiling techniques with tires at 50 PSI. This SUV is going to be a real challenge.

    Hi Harry and Ballegre:

    ___In the case of the Pilot, you both have an EPA destroyer! Around town they ill not but on the highway, they will pull numbers so far above their rating you will be shocked after setup and just following the basics including between the speed limits up to the speed limit, DWL and DWL.

    ___Here is the Pilot’s sibling, the Acura MDX as I drove family members to O’Hare from the Far Northern IL. suburbs and back yesterday.

    ___With regard to Aero mods, they will not allow this kind of EPA pounding numbers but your right foot will!

    ___Good Luck

    Well I'm lost. There's no way I can even approach 37mpg on the Pilot. I also drive an Audi S4 with 24/17 EPA MPG and can hypermile up to 35 MPG on highway. Using those same techniques on the Pilot simply don't work.

    I'd love to know what others are doing on the Pilot.

    Anyone happen to know what the drag is on the MDX (can't find it). The Pilot is .36 (my Audi S4 is .31). The Pilot and the MDX do have very different body shapes.

    Hi Ballegre:

    ___The first gen MDX has a Cd = to that of your Pilot at 0.36. This is not about aero drag but driving habits and techniques. Trust me, your Pilot is worth every bit as much as the MDX if not more due to possibly even lower weight. The Michelin X-Terrains on the MDX are running at 44 #’s currently if that helps.

    ___Good Luck

    Lots of interesting stuff there Wayne. I think it would be amazing if everyone who couldn't afford a newer FE car could use these tips in thier daily driving and watch the fuel cunsumption drop, then tell thier friends. Info like this seems hard to find. Thanks!

    Two questions.

    1) Is there a 30, 40, 50 and 60MPH FE chart for a regular non-hybred vehicle?

    2) You say that max AC reduces FE. My AC is not temperature sensitive (it doesn't cut back once a certain temperature is hit). That being the case is there any difference between the high and low setting other than the fan speed?

    Re: Beating the EPA - The Why’s and how to Hypermile.

    Hi Mr. Merryman:

    ___You hit the nail on the head!

    ___Quads4444, every vehicle will have a different 30, 40, 50 and 60 mph speed vs. FE curve so you will have to find that one out for yourself with a calibrate ScanGauge attached. About the A/C, probably not. MAX will go into recirc w/ max fan speed if it is an automatic selection based unit more than likely. If you can learn to cycle you’re A/C while sitting at a light or when accelerating back up to speed, leave the fan speed alone but shut down the A/C compressor. Once back up to speed, go ahead and start the compressor back up. This cycling of the A/C unit will definitely help. There are a lot more techniques wrt the ventilation system to use so just ask ;) Around town driving is where the A/C unit takes the harshest toll on your overall FE so use it wisely if you need it at all.

    ___Good Luck

    Thanks for the quick reply, Wayne.

    Yes, I can't wait to get my SG-II and get the 30, 40 50 60 MPG for my 99 Hyundai Sonata.

    I've been estimating best FE and speed based on the fueleconomy.gov website which shows a little chart that suggest the best FE is in the 50s.

    This is helpful, but obviously much too general. As you say, you need to know the specifics of your own car.

    Hi Quads4444:

    ___I have seen that gif many times on the Fed’s site and it just doesn’t do the average vehicle justice :(

    ___Here is one I finished up on the 2009 Toyota Corolla XRS review vehicle we had in our possession a few weeks ago…

    2009 Corolla XRS - Reasonably steady state (DWL) FE tests

    ___50 at 50 is about the best she can do at night while simply DWL.

    that chart that wayne has posted is very accurate, it varies btw cars also based on aero, and also if you have an auto vs a stick where you can shift on command at a much lower rpm.

    I get my best anywhere from 38mph to 52mph, my car is an auto v6 and is usually reading 38mpg dwl.

    pulse & glide brings that up to about 42mpg.

    Hi
    I Own A 2008 F150 4x4 And I Just Got It, So I Am Into The Gas Problem Can't Trade It Yet For A More Fuel Efficient Vehicle, But However I Have Been Practicing Hypermiling On My Truck .

    I Have Made Trips For About An Hour On Highways And On The Car Computer Shows 27-28 Mpg , I Enjoy Hypermiling , Even When My Wife Gets Mad At Me Because Of Low Speed Or Applying My Own Techiniques.

    I Just Learned Todat That Tire Pressure Is Very Important.

    I Live In Douglas,az When You Have A Forum Nearby Please Let Me Know

    Thank You

    Thanks for putting this together Wayne. In the past couple months since I started working on hypermiling, I started a thread (Hydrocarbon Miser) on another site to encourage the readers there to do more than complain about the rising fuel prices. So far it has only been myself posting on a regular basis but the thread has a lot of regular readers, which I take to mean people are listening if not sharing.

    I just added the basic hypermiling techniques from this guide to the thread and linked back here and to CleanMPG. If there is a problem with this please let me know and I will change or remove it as needed. :D

    Greetings fellow hypertypes!
    Just another fuel sucking american guy here, trying to undo a lifetime of over consumption and show my 2 teenage sons that saving gas, the earth, and the pocket book, can be safe and make driving even more fun!
    Appreciate your work on this site-very well done, and hope you all share what is working for your mileage. Does this adding-water-kit actually work? Where can I get the real scoop on this, as any mistake here would seem very bad for engine, very bad bad bad...
    Thanks so much!

    Welcome brigitte and dpmurf!

    Forget the water stuff! So far, we believe it to be a placebo effect at best. The only gain with it is for the bank account of the seller of the info or system.

    You will gain much more (for FREE) by reading Beating the EPA****

    Print it off and make it a mandatory read for your sons as well. Just apply one method at a time and watch your mpg grow!

    What kind of vehicle do you drive?
    Whatever it is, you can improve it's mileage by 10%, 20%, to over 100%.

    First I’ll give you a little background history. I bought a brand new 1999 beetle. It was delivered in Feb. of 99 and it paid about $650 more than the gasoline version. I’ve tracked the MPG since day one. I’ve always done a combination of city and highway driving over the years and I’ve gotten around 46 to 48 pretty consistently. Diesel has always cost less than gas until 2004 so the $650 premium that I paid was returned very quickly. I now have 150,000 miles on it and most of the guys in the TDI club get 375,000 to 500,000 miles out of their engines.

    Last year I read about hypermiling and have incorporated some of the techniques into my driving. I coast down hills, observe the speed limit (25 to 35 in this city, 55 highway near the city, 65 between Milwaukee in Madison, Wisconsin. I try to judge stoplights, roll through stops when safe, park so I don’t have to backup and turn off my engine at long stops.
    Right now I get in the upper fifties generally around 56 to 58 MPG. I replace a stock tires with Michelins and I run them over pressure about 5 to 10 pounds.
    I am very excited about this extreme MPG VW announced on this website. This has been in the works since 2000 and the prototype did about 285 MPG in 2002 tests.

    There has been talk about the styling-looks too weird. Well how about the smart car do you think that looks normal? Those things are selling like hotcakes. I think there’s a market in the United States for this car.

    Even price of oil is dropping right now, OPEC has already called an emergency meeting to get the prices back up.

    How about a 235 MPG commuter? I’d buy one and love to drive it to work every day. I hope this is really true for once!

    Re: Beating the EPA - The Why’s and How to Hypermile

    Hi all, great to find you and the forum. I have to haul cargo a lot and have been driving a Suburban for several years. I had no idea anybody else on the planet did anything like "hypermiling", but I've been using basically the same techniques to boost my FE. I'd gotten to where I could get 20-21 MPG highway with the Burb.

    Well I just bought myself a Tahoe Hybrid. It's great. I use most of the same techniques I was using before but haven't tried FAS with the hybrid (afraid I'd mess something up?). I'm getting 27mpg or so on flat-ish highways. I'm going to do a speed FE test tomorrow.

    Any specific tips for the Tahoe Hybrid? Again, I get ~27 on flat-ish highways, and in-town too for that matter as long as it's flat. The big thing that kills the Tahoe FE is hills.

    I'm constantly monitoring the instant/average economy, along with the display in the nav screen that tells you when you're running electric, gas or both, V4 or V8. I feel that I could increase the FE if I could control what's happening when. I think the gas engine is way too anxious to kick in at slow speeds with light throttle, and I also think it could stay in V4 a lot of the time that it kicks into V8 (you can see the "Instant Economy" drop significantly when it goes to V8, with throttle steady).

    Thanks for your comments and advice. :)
