i just put it in neutral and coast to lights... 35mpg

 

just don't let off the clutch too fast and you'll be fine

 

i try but it's kinda weird...i usually try to slow down to somewhat meet the rpm

 

blip the throttle in neutral without the clutch pedal depressed to save the synchros

clutch in, move to neutral
clutch out, rev engine while in neutral
clutch in, move shifter into gear
clutch out to engage gear.

repeat per gear and your trans will last a lot longer.

please explain how it betters fuel economy.

if you don't blip the throttle the injectors are cut off because the wheels/trans is keeping the engine spinning.

you'll save gas, but your clutch, synchros will hate it.

not worth it.

 

i use it to slow down my car...saves the live of my rotors and brake pads

 

I use my brakes to slow my car.

 

I just slip it in neutral while slowing down or going down hills. I did notice a major increase in gas efficiency

 

^I do that too. On a highway that leads into my city I can coast for a good 2 miles. I love when people pass me and we all get stopped at the lights anyways.

this is the worst reason to do it ever.

1. it makes your engine wear out faster
2. it makes your synchros wear out faster
3. it makes your clutch and pressure plate wear out faster
4. it wastes gas
5. pads are maybe 50 a set and will last you at least a year
6. rotors are cheap


rotors + pads cost way less than drivetrain rebuilds.
rotors + pads are way easier to replace/change than drivetrain components.

 

i've had an old bmw 316i 1984 and downshifted numerous times.. had no wear and tear except the usual ageing. Only wear and tear you're going to get is from old age unless you beat the **** out of it.

If you downshifted why would it waste gas?
if that's the case then automatics eat ASSLOADS OF GAS.
in the 316i i had the stock clutch in it from 1984 and original synchros
so i'd like to know where you got your info from.

also you say downshifting also gives wear and tear on pressure plate and clutch.. well it's no different then shifting period.. so if that's the case then shifting just ruins the whole tranny

this downshifting has been dragged out to long..
Just downshift normal without over doing it and you'll be fine. Downshifting is no different then regularly shifting. THE END!

 

It wastes gas because the engine is at a higher speed while downshifting than braking in neutral.

 

well if that's the case then automatics eat a lot of gas. Gas is only given by the amount you're pushing the throttle in not at which rpm you're at. Why do you think they call it a "gas peddle"?

lol

you have three options when downshifting.

1. let the transmission speed up your engine for you (stress on drivetrain)
2. spin the engine to the right speed (wastes gas, still puts stress on synchros unless you double clutch)
3. spin the engine to the equivalent speed while double clutching (wastes gas, no extra load on trans)

either way it's not worth it.

If anyone says "I do it because it's fun" or "I do it so i can practice heel toe downshifting so that when I road race I'm ready for it" or "I do it to impress chicks"

Those reasons would make sense.

If my engine is not getting gas and firing while downshifting, why is the exhaust so loud? And automatics do eat more gas than standard.

 

1)Stress is on drivetrain regardless downshift, upshift
2) whether you downshift or normaly shift you're still putting stress on your synchros
3) there are to many factors on "wasting gas"
4) let me recorrect myself, the "gas peddle" only depicts how much air is given in the ratio of 14.7:1 gas therefore downshifting into higher gear and not giving it "gas" you're really not "eating" gas up. If you're constantly in the high rpms to keep it up there then yes you are eating gas.

now if you downshift for the "i'm kool" type then you're just retarded.

automatics eat more gas then manuals because the TB is always open and your TB is connected to your "gas peddal". I never said they didn't eat more gas then manuals i just said if downshifting eats more gas then automatics eat a lot of gas cuz they downshift a lot. Automatics downshift reasonabley and that's not the reason why they eat gas.

and when i'm talking about downshifting i'm not talking about downshifting to get your rpms back up i'm talking just downshifting to slow your car down not giving it "gas"

Your exhaust is loud because your at higher rpms.
