4) Learn pulse and glide technique.
5) Plan your routes that are either the shortest possible, or the most fuel-efficient possible (few traffic lights, roads without a lot of uphills, roads with downhills to coast down, etc.)
1. Yup, I did some reading for a few days before I started this thread. As it is I try and accelerate slowly in town, (keeps the exhaust down and helps MPG). I try and keep it below 2500 RPM as much as possible. I already avoid drive thru's for the most part.
2. Already do that. I called it progressive braking though. Where I would increase pedal pressure before the light and try to time it so as I was coming to the line, the light would turn green, and I wouldn't have to come to a complete stop. And if I know I'm gonna get hit with a string of red lights I accelerate enough to get going and then let off and coast as long as possible.
3. Unless it's first thing in the morning (5:30ish and I'm stopping at Dunkin for an iced tea). Other than that I always go in. Less hassle that way and no chance of getting stuck behind the soccer mom who just ordered food for her, her husband, and the 5 kids in the mini-van at the drive thru.
4. I'm still working on pulse and glide.
5. This is something I'm working on as well. The route I used to take to and from work had a lot of up and down hills. The route I've started taking is slightly longer but it's more of a gradual incline than the other way. I'm debating on taking route B to work and route A home since A would allow me a lot more downhill time and route B tends to get more congested in certain spots in the afternoon/evening.
Since last time I put ~340 miles on her. I'd say 85% of which was highway. Although a chunk of those highway miles were not cruising miles. And the 15% of the miles that were not highway I'd venture that 5-10% of which was in heavy stop and go traffic. Lastly, most of this trip was with the front windows halfway down. The vents just weren't cutting it for cooling purposes and my A/C is still out of commission. Before this trip I had topped off the tires at 40 PSI and started adding the 2 stroke marine oil.
The results were just shy of 27 MPG. I believe if the highway miles had been more of a cruise speed and the city miles were less congested my mileage would've fared better. So now that I have some basic city and highway estimates I'm going to start doing my Eco Mods that I described earlier. First things first and that will be my upper grille block. I'm gonna take a trip to WalMart tomorrow and see if I can find those poster frames I mentioned earlier. If not I'll have to find something else.
I've also been giving heavy thought to converting my CAI to a WAI and making a box to act as a heat shield of sorts and try and direct the flow from outside the engine bay. I remember seeing a thread on here recently about it. Time to see if I can find it as well. I also probably need to change my filter out so I'll do that too.
Found the intake thread I was thinking of. Google ftw!
Also, I remember reading something on Maxima.org about wrapping the IM and intake piping in some sort of heat reflective tape. Might have to dig that up too.
