How I'm getting 25+ MPG

Alright, I've talked about it a little bit, bragged about it a little bit and figured I would let everyone know what I have done to my car to help improve the milage. None of it is anything too special, but I figured that I would make a list if anyone wants to referance it.

March 2005
17.49
21.57
20.79
24.87
21.86
Average MPG: 21.316 That was with some highway driving mixed in, 350 miles in 3 days between filling up. I don't think it was all highway, but there was definately a good mix of it in there.

Now, everything that has been done:
Spark Plugs
Spark Plug Wires
Oil/Filter (5W30, filter from Acura) every 3,000-4,000
Transmission Fluid
Coolant
Air Filter
Fuel Filter
Exhaust Manifold

That is really all that has been done to the engine. The other three factors are:

Tire Pressure - I usally keep mine up a bit higher than reccomended. It isn't the best for performance, but I don't do any performance driving in my commuting. I have begun to keep it at about 34 PSI all the way around, a little bit more than reccomended + 10%.

FP 60 - http://www.lubecontrol.com/ -
FP60 increases combustion efficiency, lubricates fuel pumps and injectors, cleans the fuel system, and potentially increases mileage. It scavenges water and moisture from the fuel system as well so the resulting mix can be burned in the combustion chamber. Combustion chambers can be cleaned using FP60.
You add in a little to every tank, 1 oz to every 5 gal of gas. Some people reccomend an initial "shock" treatment, of about double that. I have been using it with great results. It is expensive, but I have had a definate savings even considering that.

Driving Style: For the msot part, I drive pretty conservatively. I prefer a smooth ride rather than a fast ride. I usually don't accelerate much past 3,500 RPM, try and roll to stop lights and avoid stopping, that sort of thing.

September 2005
25.09
28.72
24.48
24.92
24.36
Average MPG: 25.514 This month had a similar amount of highway driving over time on it, and the rest is the same driving as usual. Not much has really changed about the coniditions I drive in, so I think it is a pretty fair comparison.

All the MPG numbers were figured using (Miles Traveled/Gallons pumped to full).

As you can see, I went from 21.3 to 25.5, about a 20% increase. It cost some money to get there, but I've got a strong running car, with consistant savings every time I fill up.

Any thoughts?

What do you get with pure highway driving?

On a 2.5 I'd assume 28 or 29...

Nice, but I get that in my V6 tl and all I have done is thrown a new set of plugs in... currently have 115K miles... I guess it is mostly the weight of your foot... But props for making it work

Having stock wheels and not too sticky tires will definitely improve your gas mileage

Pure highway, usually about 28. I don't usually use the CC (can't really on 95/195, you can once you get up to 89/93 though) and am usually between 80-90mph, with a little bit less air in the tires (a little more grip if I need to make a sudden move).

Tire pressure is a big part of getting good gas mileage. Also, leadfooters need not care about MPG.

Also, how big is our tank again? 14gal?

Yeah, tire pressure makes a difference. I usually do about 5 psi higher than is recommended on my cars.

Yup, it's either ~85 in the left lane, or like 50 in the right hand lane, or any random ass speed in the middle. It sucks. When I go up towards Maine/Vermont it is nicer though, onc eyou get off 95 everything is better.

17.2 Gallons.

When the fuel light comes on, you still have a few gallons left. That way you can drive another 50+ miles, ample warning.

Heh...I always fill up when the needle is at the last 1/4 mark. When I fill up, it usually tops off around 10 gallons. It's weird!
