hey everyone, just signed up after reading the 65+ efficiency mods. I found the site by google searching weather or not lighter wheels/tires will help my fuel economy enough to make up the cost difference.

Since I do mostly highway driving it looks like the answer is no, so now I'm going to figure out what I can do to make a difference. I get pretty good mileage for my car just by driving slow and coasting when I can. I really wish I could re-gear the trans to cruise at a lower RPM on the highway but I already have the lowest final drive and 5th gear available.

Welcome to the site.

I am working on a "Seafoam Injector" currently and been taking pics for the project. The reason for the injector would simply be for carbon build up. The injections can be done any time you have someone riding your rear bumper also :)
