Replying to: wvgasguy (Jul 23, 2006 11:15 am) With so many places to see the FE...it gets confusing. Can you confirm my understanding???...if you will graciously give me a few minutes....your previous posts have been a significant part of my decision process to buy the TCH! THANKS!!! Here's how I currently understand the many guages: Left of the Speedometer: an analog guage showing instantanious mpg. This is clear! lol Under the speedometer, there is a multifunction guage...among other things, it shows: 1. A stepped ECO Drive level guage...this is the average mpg for the current trip, in bar graph format. Seems this resets every time the car is started. 2. Tank average: mpg for the current tank (only resetable automatically after a refuel??) On the NAV consumption screen: 1. bar graph showing average mpg by minute, for the last 30 minutes of driving. Bars change color to show the previous trip, until current trip goes over 30 minutes. 2. "Average" mpg... average for the current tank since refuel? Is this resetable? or only automatically after a refuel? Is this an exact duplicate of tank average display under speedoneter? 3. "best" ....from your description above, I understand this to be the highest instantanious mpg recorded in the bar graph of the 30 min???? 4. "Reset" restest curent info display, 30 min graph, and best??? 5. "reset all" resets tank average, 30 minute bar graph, "best" and average mpg (on this nav display)?????? I would like to be able to have a running total for the mpg that doesn't reset at refueling. So...is there a running total mpg that can be kept indefinately...as in "since I have had the car" average? thanks for your help..this is one heck of a car!!! I will be an active poster here with info on my experiences, here and in the thread "New TCH Owners, give us your report" I noticed this morning, there is a blue colored "ring" that shows up around the instantanious mpg guage and speedometer when the mpg reaches a certain level...40mpg??? Sorry for long post!

Trip to the store, red light to red light, trip to mom's what ever you want to measure. I set it on trips I make frequently and experiment with slow starts, steady driving and coasting techniques to see what's the best way to drive a specific route I drive often. It's not for the tank average, it's for the trip and it can be used, I'm 99.9% sure, over the course of several tanks like on vacation. The "best" screen will be reset to a higner number when you hit the reset and your trip has a higher average than your previous best. It's probably meaningless to anyone but you. Reset like I just did on a trip to the store and I got 49 mpg. I can use it as a coversation piece I suppose. Reset does not change the "best" if the current is lower. I don't think there is a running mpg for the total unless you just don't ever reset. That's probably not practical. I keep my running total on an EXCEL spread sheet I keep on my laptop and then I move the same data over to the GreenHybrid.com "COMPARE" page. (Check it out for my tank by tank milage) If you just keep your receipts and enter the milage and gallons there it will keep your running total for you. Since you can go 600 miles on a tank it's not all that often you'll need to do this.. I believe the blue ring shows up when ever you get to 36 mpg, the same FE where the ECO gage rewards you with an "EXCELLENT" as you shut off the system.

Manufacturers design the tires to match up with the cars. They expect a specific tire surface interface area on the pavement to create a desired safe handling characteristics. Just because a tire has a maximum pressure rating does not mean it should be achieved. If you put the same tire on a 3500# car and a 4400# car you'll want more pressure in the heavier car to create the right surface area. Increasing the pressure on a lighter car however lessens the tire contact area and thus create a longer braking distance as well as less surface area for grip. Granted there is some "play" in these numbers but increasing pressures 30% over design is pushing the safety and handling aspect of the tire design for good FE. Tires are designed with a maximum pressure so that they can achieve a wide range of applications, not so you can pump them up hard on your TCH. Also (someone mentioned the max on the Michellin was 44 psig) running at 42 cold pressure on concrete highways at high speed in hot weather will probably exceed your maximum tire pressures. If you blow a tire and wreck your car don't put it past your insurance or whoever you decide to sue to check your pressures on your other tires or for that matter your comments on this website to see if you purposely exceeded recommended pressures. (I'm not a lawyer, just spend a lot of time tring to figure them out at times) I realize this won't change the minds of you die hards. Don't even want to. However many novices watch these forums for ideas and "buy into" just about everything they read from synthetic oil, high tire pressures and running in neutral. All these things should be (re)considered after research and study, not just as a "I wanna do it to" attitude.

Replying to: wvgasguy (Aug 28, 2006 2:33 pm) You should follow the auto manufacturers guidelines for the proper inflation of your particular make/model. And of course, the pounds of inflation are always meant to be adjusted on tires that have not been run more than a mile or two. That will give you the proper operating pressure. |

Replying to: wvgasguy (Aug 28, 2006 2:33 pm) As an FYI, I have an expensive digital air gauge and checked the air pressure after driving my 2007 TCH for just over 15 miles and registered 38psi...

Replying to: agnosto (Oct 03, 2006 11:07 pm) Wow, every morning. That's dedication. I assume you mean that the tires do not exceed 1-2psi above the recommended pressure? |

Replying to: regal1945 (Oct 04, 2006 2:29 pm) I would agree that daily is a little extreme. However, if the TPMS has a 5psig (?) lower limit then I would not want to totally rely on that. That to me is just a back up for a severe pressure loss. If I set my pressure at 32 I wouldn't want to be driving around at 28. Not that it would hurt anything but FE, but I would want to keep them close to what I have determined to be optimal. I usually check once a month and when the weather starts changing
