Mileage improvement mods
Does anyone here care about gas mileage or is everyone hell-bent on acceleration? I recently upgraded my air filter, y-pipe and exhaust with a K&N/JIC/Amuse R1 combo for looks, sound, and power, and my normal mileage went from 25 to 27. So with $3/gal gas prices, are there things that you've done to improve the Z gas mileage, intentionally or otherwise?

I have a Popcharger and Nismo cat-back. Havent really done any tests as of yet, stiff loving the new sound too much But I am driving from San Diego to Virginia Beach on Tuesday and Ill be logging everything.

Allright, I'll add one more. Changed over to Mobil 1 oil and filter yesterday and took the same trip to work and back this morning (minus the working), and saw 28.8 mpg avg. Not bad at all considering I was going to change the oil anyway. So between the exhaust and oil (and the engine being broken in), I picked up almost 4mpg. Anyone done any other mods with fuel economy in mind?

Heah, I heard about grounding systems. Unless there's something already wrong with one's wiring (old and rusted) grounding systems are a waste. We did some testing over on the SpecV forums, and there was absolutely NO benefit for new cars. I wonder if iridium plugs or the new CD ignition system I saw here recently would have any effect on mileage. I would much rather give my money to a high tech Japanese firm than a camel jockey, anytime.
Yea, 29 mpg is only a dream when I put my foot in it, but as long as I just keep up with traffic instead of trying to race everyone, it is nice.

Don't flame me on the looks aspect, but lower your car and give it a slight rake, with the rear slightly higher. Add a front air dam and side skirts, and it will pull the car even lower on the highway, reducing the undercar turbulence. I do not think getting 35 mpg on the highway is too dificult with the right mods, and 40 is not dreaming.

I see that the HKS Twin Power DLI II has a lot of potential for improved gas mileage due to higher ignition energy and hence more efficient combustion. I just ordered it with the Denso Iridiums. I will post the effect next weekend after I install these and have a chance to put some miles on it. I doubt the combined cost ($583.) will ever be made up by the improved gas mileage, although several have claimed improvements of 3+ mpg in a recent thread. But then again, I would rather pay my money to Japan than to the middle east.

Synthetics are suppose to reduce friction and improve MPG. While VQ engines are rated for X-W30 oils, Fords are using thin 5W-20 oil to improve their fuel economy (some would say at the expense of engine logevity, but most of the time the engine will outlast the rest of the car).
