130lbs of additional weight would not offset a 10% gain in FE. The only time it would even have an affect on FE would be accelerating and going up hills. 99% of my driving is cruising on expressways and I live in Southern Michigan which is extremely flat.

Weight does play a role but for most people it's probably not as large of a factor as just getting things more efficient. Weight and power to weight ratios matter much more in things like racing.
