Here's an interesting (I think) observation...
Driving becomes second nature and driving habits truly ARE habits! In two days of my bet with the wife, I have caught myself using DFCO, accelerating very slowly and popping the AT into N at trafic lights. I am having to make a conscious EFFORT to drive "normal"! |

I had to do the same. The good thing, is that you get used to it quickly! After only a couple of weeks of driving better, 65mph seems so FAST!

how much gas is saved when turning off car immediately after parking as opposed to waiting to take seatbelt off, roll up windows, etc?
I ask because I left my old car running at a drag strip with the keys locked inside once... for maximum performance, I used race fuel and kept my gas tank practically empty. It idled for a couple of hours before I got back into it and was still able to get me to the nearest gas station many miles away. |

I imagine someone with a scangauge can tell us the gph useage idling?

Yea it's probably not *worth* doing, but it feels good to know that however small the amount is, I'm using the absolute LEAST amount of gas possible. It just doesn't make sense anyways, why let your car run while you do things that you could do with it off?

The A/C does effect MPG on 4 cylinder engines,the Myth Busters tested this on 2 V8 trucks if I remeber right.They proved that windows down up until 55mph was better then the A/C on below 55mph.Above 55mph,A/C was better then windows down above 55mph.Now that was on a V8 engine,I would say on our engine windows down would be best until about 75mph,then I would crack the windows and still not turn on the A/C.
And I thought our heater was just heat coming from the engine bay,no coils or anything. Last edited by eco; 10-21-2008 at 09:38 PM. |

What I don't really understand is what some hypermilers do: turn off their engine as they approach red lights, stop signs, etc... I know this still saves gas but the engine starting stresses the engine and the starter, so I don't know why you would want unnecessary and additional stress on the engine/starter :?

Nate,
On modern, small engine, fuel injected vehicles such as the Yaris the wear and tear and fuel usage of a warm start is equivalent to just 7 seconds of idling. This means that if you will spend more than 7 seconds coasting into and then sitting at a light (or just sitting at a light if you have the AT) it is easier on the vehicle to be turned off and then restarted. Mike b, The Yaris consumes 0.2 GPH at an unencumbered idle. While that may not sound like much if you think about how much time you spend idling over the course of a full tank it becomes a significant factor in your overall mileage. eco, Several folks on this site with ScanGauges have done extensive testing in the past and we all found the same thing: In the Yaris it is always more efficient to have the windows down than to use a/c, regardless of speed. Unfortunately that thread was lost in the hack. As for the heater the Yaris does have coils for producing heat on a cold start. Once the coolant temperature reaches a threshold the coils deactivate. Using the heater does affect mileage, by the way, although much less so than using a/c. It steals heat from the coolant and this causes the ECU to run a richer fuel map in an effort to produce more waste heat to reheat it.

No Brakes
Drive like you have no brakes. This forces you to take it easy and employ long coasts...with engine off (of course).
For Bailout, I like the bike rack. Quick query, on an old lost thread you discussed the special chains you snap on for snowy conditions. Who makes them and where did you purchase? Thanks! Ken |

Turning on the heater only causes the thermostat to close a little to compensate for the temperature loss that would otherwise occur through the radiator. Any modern (or old) engine produces so much waste heat that there is absolutely no need to make an effort to create more. |

Dude, I am so ready for this battle to begin...
I also really want to know what effect running the heater has.

As an example, on a February morning I can climb the mountain I traverse every day with at least one passenger and snowboard stuff and other weight involved, and by the the time we've reached 7,500 feet of elevation the coolant temperature has dropped into the mid 170's F. Without warning my already shitty climbing mileage will dip another 10-20% and by the time we're reaching the summit at 8,900 feet the coolant temperature is back up in the mid 180's and my mileage returns to the expected amount. Blocking the grille helps the car warm up quicker and helps it to maintain an optimal coolant temperature. With one in place I no longer see those big dips in mileage in the coldest part of the day as my coolant temp stays in the mid 180's. Quote:
They are called Spikes Spiders (the "Compact" version) and I got them directly from the manufacturer at http://www.spikes-spiders.com/ . I just added the mounting brackets back onto my front wheels last weekend as we've already had our first snow of the season. Thank you for the compliment on the bike rack. Just wait... in a few weeks I'll have pictures of the snow sports adapter attached to it and an antenna farm of snowboards and skis sticking up out of it.

Drive like you have no brakes? That is why I get good mileage, because most of my previous cars had inadequate brakes, so anticipating stops, not slowing down for corners, etc, became... habit.

Shush!

but bailout, wouldnt that same issue effect those of us living in warm climates much less if any at all? the coldest it really gets here is like 60 degrees...
