Yes. It applies to downhill travel too.
 
Even though it may be necessary for safe travel, or to maintain speed, energy is wasted each time the brakes are used. Unless you pushed the car up the hill, the energy that got the car up the hill came out of the gas tank. In the absence of braking, you'd have traveled further on the way down. That's the miles part of miles per gallon.
 
The exception to this is applying the brakes on a stationary car whose engine is not running. That will not effect gas mileage.
 
What is so hard to understand about this?

Yes yes we get it! As long as an engine is on and the vehicle is not moving or not moving freely without the restrictions of brake whether it is going downhill or uphill, it is energy lost and decrease of MPGs, because the engine is still burning gas and either not moving at all or being restricted by the brakes.

Cool, can I ask where you got the fan that heats the car up that does not draw any power to run lol

According to the technical mechanic guys and computer at the Mazda dealer...........................there is nothing wrong my Mazda5. What a suprise . The finger valve things, or whatever he called them, that inject or control fuel are working fine. The brakes are perfect.
 Here is the possible Problems:
1. The actual average mileage according to Mazda is 23 MPG combined.
2. With "only" 1300 miles on the car, it's not "broke in" yet.
3. Driving style.
4. This is the most probable cause to them for the MPG being off "slightly", the gasoline companies blend the gas differently from summer to winter. The "winter" gas mix fires differently, faster. This makes the cars start faster and get warmer faster. The "winter mix" also results in lower MPG for everybody.
 
So there it is. Keep the tire pressure up, they documented the issue, and see if the MPG improves in the spring.
 
A " song and a dance " or " legit "??

You never mentioned what kind of mileage you got on your Venture in the month or so before selling it -- on the same roads.

I said the heat was free, not the air.
 
The air is almost free. Unless you open a window in the winter, you need the fan for fresh air to keep the windows from fogging. If it's above freezing the a/c helps too, but you have to pay for that.

I didn't track the Venture mileage, as I was to busy trying to keep it from falling apart while looking for another car.

Bottom line, I honestly think that the low MPG your getting in you MZ5 is a combination of two things:
 
1. The Ethanol based gasoline you use
2. Your MZ5 is still new and although break in period is over (600miles) the engine itself is still fairly tight and not fully broken in.
 
IMHO.
 
20.5 MPG's rounds up to 21 which is what the city's rating EPA is for our MZ5 (automatic trans.) I own a 2006 MZ5 Touring Auto and I constantly get 22-23 and in a few occasions 20-21 mpg, unless I go on a long trip which then just barely reaches the 27-28mpg level, which is still close or right on the highway rating.
All in all, you are still ina better place with your MZ5 then any other MAV (read mini-van) because others such as the Sienna, Odyssey, Caravan are probably in the 16-18 mpg level for city and 24-26 highway. Plus MZ5's are just plain cool and sporty looking with great handling.
 
I wouldn't worry about it.

I'm just being partially sarcastic. Making left turns also uses more gas than right turns, so maybe we need to plan our route better! Actually, turing the steering wheel uses more gas too, so we should take more straight trips! The main thing folks should try to do to save gas is go light on the gas pedal. By the time they're braking it's too late to save the gas.

Actually, turn the wheel all you like, I think our 5's have electric steering and not pump-driven steering off a belt - woo hoo!
