10mpg lowest for me around the city lol

 

i save gas by not driving my car check sig

 

Maintaining your vehicle can not only add years to its life and resale value, it also saves gas.

1. Make sure your tires have the correct amount of pressure in them. Tires that are under inflated can save fuel and save lives. For every 1 psi drop in pressure you lose a 0.4% in gas mileage. Having the correct tire pressure can save you up to $.08 per gallon.

2. Make sure you change your air filter at regular intervals, usually with an oil change. This can improve your gas mileage up to 10%, or about $.25 per gallon.

3. Using cheaper gas may not always be the best answer. While the fuel that comes from the tanker truck meets the octane ratings and is mostly the same, each gas station adds there own blend of additives. Union-76 and Chevron claim to have beneficial additives in their fuel to protect your vehicle while the generic name at the corner gas may be putting additives in the fuel that meet the bare minimum to retain fuel quality and prevent contaminates that fuel is susceptible to. These lower grade additives may actually do damage to your fuel system and vehicle in the long run.

4. "Topping off". Many gas station state that you should not "top off". This is good advice. When you try to squeeze that extra amount of fuel into your tank, you get charged the extra amount but a lot of the gas that you are paying for stays in the hose and never actually makes it into your tank!

5. Keep your vehicle tuned up. Studies suggest that you can improve gas mileage by 4.1 percent or 8 to 80 cents per gallon.

6. Keeping a safe distance behind the vehicle ahead is not only safe but it allows you to use the brake and accelerator less often reducing wear and saving you gas. If you are too close constantly braking and accelerating, following the lead of the car ahead, you are using gas and putting wear on your brakes more than you have too.

7. Use a grade of oil that is recommended for your engine. Using a higher viscosity oil makes your engine work harder than needed and use more fuel as a result. Using the right motor oil can save you gas by .03 to .06 cents per gallon.

8. Driving the speed limit saves gas. Driving 5 mph over 60 mph is like paying .15 cents more per gallon.

9. Studies show that warming up your car for more than 45 seconds is unnecessary. Letting your car idle for long periods of time burns a lot of fuel. TIP: Go into a restaurant instead of the drive-thru. Starting your vehicle uses much less gasoline than idling through the drive-thru window!

10. Use over-drive if you have it. It reduces the revolutions of the engine and less fuel is needed.

You can save a noticable amount of money at the pump with these tips to save gas.

Wow, you know nothing about engine design and tuning, fluid dynamics, let alone fuel efficiency.

First off, a smaller throttle opening increases efficiency at low RPMs because the engine doesn't need much air VOLUME but it does want air VELOCITY which is increased by a smaller throttle opening. Technologies like dual stage intake runners like found in DC2 GSRs are based upon this effect. If you don't understand how a smaller pipe increases fluid velocity, I suggest you sign up for a physics class at the community college.

Second, the gas pedal is not simply a throttle control. The ECU uses a throttle position sensor to determine where exactly the throttle is at, and adjusts air fuel ratios accordingly. At WOT, an engine runs MUCH richer because the ECU tells the fuel injectors to push out wider pulses of fuel. So 50% throttle at 2000 RPM is going to use much more throttle than 5% throttle at 5000 RPM.

In conclusion, you're an idiot.

 

Wow, insult the guy, why don't you?

It's been proven that even if it seems counter-intuitive that pumping losses can be significantly reduced and you end up with BETTER MILEAGE if you treat the throttle like a switch - off or on, with on being somewhere between 50 and 75% throttle. Shift @ 3000 and treat your throttle like a switch for greatly improved mileage.

Running WOT/open loop IS a huge waste of fuel and serious polluter.

Chances are you'll need a ScanGauge to find that optimal throttle position for a given car, though.

 

The only techniques I see as unsafe or illegal are those that involve killing the engine or drafting a big rig at a close distance. The rest of the techniques, practiced in the proper time and place are perfectly safe when performed by an aware driver - and someone doing this sort of thing is going to be a VERY aware driver because so much of the technique derives from paying attention to what's ahead of you to minimize loss of momentum.

If you're in a spot where the pulse and glide will piss off your fellow travelers, you just take it easy.

 

Actually you want a warm air intake.
For similar reasons a CAI "increases" HP (tho not so much on the S)
a WAI can help to increase MPG.

 

So how much $$ does that saves you per year? Have fun in your POS.

 

yeah... i don't understand the reason for a shitty DD. live your life damnit! if the S is too "rough" for you as a DD, then get a nice, comfortable/safe DD. if you cant afford that, then maybe you shouldn't own the S to begin with. BUT thats just me.
