so i was able to get about 1.5 more miles per gallon on the average over the 3 fillups i did. i got around 27~28mpg. about 1.5mpg more than my usual.

i lowered my average freeway cruising speed from 80mph to 75mph
i shifted at 3k rpm on the road in normal conditions and about 3.4~4k rpm for uphill and freeway acceleration
i gradually accelerated to 3k rpm slower than usual

i kept using AC when needed, top down when felt like it

and always anticipate the traffic to minimize the usage of brakes and use natural engine slowing down brakes

so like 16.5 more miles per fill up(about 11 gallons)

last time i put gas it was $4.6999 (91octane)

so average saving of about $2.9999 dollars per fill up...

so there it is

 

nice job!

 

I do the same habits in my DD and got a 10%+ increase in economy.

 

Can't do it. My daily drive to work is just a few miles, and I can't give up my fun for a few weeks to test a full tank. I live with 20mpg if I'm lucky around town.

But, on a recent highway trip, I took it easy, limited my speed to 75mph, and came away with 29mpg.

 

Congrats, you drove like a grandma and saved 3 dollars

 

LOL...that's a good way to look at it!

 

I dont use the engine to slow the car down I just pop it into neutral and coast that way the motor is idling and in turn not burning as much gas. google hypermiling good theory behind it

 

Not bad, I live in NJ so gas prices are a little better but my car eats it up . I'm looking to get another S2000 soon I need a 4-cylinder again

 

I'm almost done with my first tank doing something similar. I haven't had occasion to drive more than 50 or so on this tank so it should be a real good "city mileage" test. I accelerate at about half throttle or maybe a little more, though (I have read that getting into a higher gear sooner makes up for the extra fuel used to accelerate faster. I think this probably depends on the car and conditions, though.) I am shifting at between 3 and 4K. Most of my commute is at 40 MPH or so, which I drive in 5th. If I take the beach route home its a little longer but with fewer stops and everybody does 50 (limit is actually 45). At 45-50 I'm in 6th. To avoid lugging the engine I do downshift if I have to accelerate at anything more than a very gentle clip. I coast a lot.

In addition to saving gas I feel like this driving style makes it easier to be smooth which is easier on the car. And I expect my tire life is improved.

But...If I can't save more than 10 bucks a week on gas I'm back to my wild and crazy ways. The e-ticket version of my commute is worth at least $10 a week.

 

That is really poor driving practice. When the car is in neutral, you are not in control. Not only that, but when you put the car in neutral, the engine is still using fuel. If you would leave it in gear and remove your foot from the accellerator pedal, you will use NO gas as the fuel injectors shut down and the engine is just pumping air through itself.
