New member here. I am liking everything I read on this site, very interesting and inspiring see what everyone does on here and no judging on what kind of vehicle they have. Whats also interesting is I am more than adequately educated in designing, constructing, and maintaining environmentally sustainable Buildings and the practices associated with that. But when it comes to the advanced practices i have been reading about here, I am not extremely familiar with it when it comes to vehicles. I am knowledgeable with cars enough to have already modified my car to be one of a kind and enjoy it more than the average driver. Such as suspension, engine performance, lighting, and handling etc.

2002 Nissan Maxima GLE Automatic 5 SPD. i will post pics after 5 posts.

I am interested in getting the best(or better) gas mileage i can get with out going too far, in other words I want my eco mods to be subtle. I want to keep my car fairly the same on the outside, which may or may not be my down fall to actually reach my 28-30 mpg goals. EPA 17 city 24 Highway. Which I have read in the Maxima world people with autos can get up to 22 city 28 highway. on average at best.
Recently i have been driving wholly concerned with only minimum fuel consumption (fc) in mind. Never going over 2,000 rpm, and staying under 60-65 at high way speeds.
I recently have been manually tracking my MPG (since the ECU is usually ambitious to the point of 3-4 MPG higher than actual) and have gotten at best so far on 90% highway trips 23.78 mpg. Which isnt bad considering that was also before I changed my so called lifetime fuel filter. It is known in the maxima world that changing this fuel filter is recommended even though its supposedly lifetime. I am really excited to see how the change helped. By judging how much I have traveled on my current tank after the fuel filter replacement alone I can easily say i got 2-3 mpg better. Will post updated mpg from that tank.

List of Eco related Mods
-Lowered 1.4 all around
-42 PSI all around
-Driving Habits modifiied/regulated for best MPG at all times
-Regular Maintenance done (ngk platinum spark plugs, filters, fuild changes/flushes, all with in 15k miles)
-Front Lip Spoiler
-No rear spoiler (dont no if bad or good for eco)
-No aftermarket exhaust, or air intake


What are some other things I can do to reach my conservative 28-30 mpg goals? I know my air filter could be changed but i have been blowing it out every so often.

Some things that caught my eye are under body aerodynamics, grille blocking, and rear diffusers. All pretty subtle if done right. i also have a grounding kit, which has helped idle, shifting, and electronics very nicely.

Thanks in advance for any info or advice!
