So thus is something I've been thinking on for s while and never remember to test.

When you're trying to preserve that lovely precious liquid in the tank, what's best?

Putting around waiting to get to your desired speed?

Or hauling a little ass and getting where you want to faster then coasting?



This question is mindfucking me. So please give me some opinions.

 

Drunk and only one spelling error. I call that a win.

 

I've found that if you slowly accelerate for a long time, you put the engine under load for a longer amount of time, wasting more fuel. It works better for me just to get up to speed, and go the speed limit.

 

lower rpms, more miles.

 

^ this.

 

This is what I have always thought.

 

ive always thought lower rpms, less gas being used.

also no boost means less gas being used.

 

just get up to the speed limit and your fine. From a stop and accelerating as long as you don't go into boost, thats the best way your going to conserve fuel. That or take public transportation or walk if your only going to the corner store lol.

 

Gentle acceleration off the line then shift @ 2500 RPM. No boost = reasonable mileage.

Boring but frugal.

 

What works for me is to shift around 2500-3000 rpm's in each gear. Even lower works in the higher gears. If you are going to be cruising around 50 mph or so, put it in 5th. Just don't stap the gas when you want to go. On my daily drive, I am averaging 29 mpg.

Try and keeping the boost low helps too. Going the speed limit helps too. I have noticed with mine, that if I go over about 74 mph on a long trip, it goes south fast. The best that my car has done was 37 mpg doing 68 mph with the air on.

Also, have your windows up. Use the areodynamics of the car. Have the a/c on low. The newer cars are made to run like this on the highway.

 

In my opinion, somewhere in between is the sweet spot. If you accelerate too fast, you're just wasting gas. If you accelerate too slowly, you'll always have a load on the engine and it will take a lot longer before you can let off the gas.

Generally, I accelerate more slowly than the traffic around me and I shift around 2300-2500. If I am going up a hill, I'll shift around 3000. If I am going down a hill, I'll shift around 2000.

If I am cruising around town at 35 mph, I'll leave it in 4th gear. Any faster, and I'll shift into 5th.

There are two things that rape my fuel economy. The main one is wind, and the second is speed.

I hope this helps you out. You know our cars are identical...

 

Talk about load.. Definitely too low of a gear for the speed. I don't care what anyone says. I only use 5th when I am at 50 or above. You are bogging the motor hardcore if you're going 38mph in 5th.

 

Only if you are trying to accelerate or drive up an incline. I've noticed a little bogging with a stiff head wind, but I'd hardly call it "hardcore".

Maybe the difference is in our engines. How does the low-end torque in my mostly-stock 2.4 compare to the low-end torque of your 2.0 SC with a long-tube header?

 

No I agree, I thought about it and 100% agree only if going up-hill. If you're just cruising along it would be fine I think, just don't use 5th to pass anyone when you're going that slow!

 

Somewhere in-between is best. Stay out of boost but don't take your time to get to the speed limit.

5th gear is useless until you hit 45 - 50 mph.

I can't really say anything becaust I averaged 17 mpg on my last tank of premium.

 

Get to speed quick and stay in the highest gear.

 

I think the 2.4 does better under really low end load. because I can putt around 1300RPM in my 2.4 just fine, but my buddies 2.0S/C feels bogged at that RPM.

 

its all in the throttle control. i like to stay out of boost around 10 to 15 on the negative side
