Gas Mileage Questions.
 

1. Does driving normal instead of flying off of a stop sign get better mileage?

2. Does starting your car on and off use alot of gas?(ex. stopping and rolling a house and starting up and leaving several times)

3. Cold weather?

4.Fast Interstate driving?

These are just general questions so dont jump my case just yet..

1 if u womp the gas the TB is going to be wide open and youll waste a lot of gas, if u drive normally you wont wate gas.

2 youll waste more gas idling for 30 seconds then it takes to stop and start you car

3 cold weather could help the gas situation. cold weather means cold air. colder air in the engine means minimum power gain, theoretically, with means better gas milage, theoretically, i would highly doubt youd notice any difference

4 i think anything over 100km/h and your starting to lose some gas milage. generally speaking though, highway driving is more efficient that city driving

hoped this helped

My 323 came with the factory manual... And it had a few interesting things to mention about gas milage...

They recommend getting into 4th gear (for those having manuals) as soon as hit at least 40km/h (25mph) and then sticking with that unless the engine starts to get so low on revs that it stutters a bit... They say this probably won't happend unless you get below 30km/h (19mph). I guess they would recommend getting into 5th gear if you drive faster ;) No note on that though.

I also found the original Swedish fuel consumption table for all 90's Mazda's.

My 323 sedan 1.6i is supposed to use 0.68 liters pr 10km in mixed driving condition. 0.80 liters pr 10km in city traffic, and 0.53 liters pr 10km highway. I guess I can turn that into MPGs if anybody wants...

Acctually cold wather lower milage but increases power slightly, noticibly.

The cold weather causes the gas to not atomize properly, so the car has to use more of it to get the same result.

...older cars used to have a "mileage meter" on them. Basically, it was just a vaccuum meter, and surprise! it indicated worse mileage the further the throttle was opened. Engine load, speed, etc all have an impact on mileage. If you take off slow from stop signs, keep the rpms low (don't be afraid to lug the car a little around town), and obey the speed limit, you'll return decent mileage. Good maintenance habits (replacing dirty air filters, putting in fresh plugs when the OEM ones wear out, maintaining proper tire pressures, etc) also will keep you from guzzling fuel.

As for shutting the car down instead of letting it idle for extended periods... this is a neat trick. But a new hybrid, and you'll notice that the engine shuts off when you bring it to a stop. Automatically. When you put your foot back on the gas, it starts right back up, and you are off! Cool, huh?

...some older cars (like my friend's old 83 Caprice) had the meter I mentioned, but they did not ALL have them...

just to cover a few obvious things.

you use more gas with higher rpms....keep the rpms as low as possible and you'll do fine.

Turning a car off and starting it again uses more gas than letting it idle for about 4.5minutes. There was a big study on this several years ago and I don't remember ewverything but I do remember that specifically. If you're going to be waiting more than 5minutes it's best to turn it of.

interstate driving is the same....keep the rpms as low as possible and you'll get better mileage.


if you're looking for better mileage you'd do better to keep your tires inflated to 36psi a piece and remove as much dead weight (i.e. stereo junk) as possible.
