Since I also own an '05 Subaru LGT Wagon, I'm VERY impressed with your 90 day and lifetime FE for that vehicle! I find it exceptionally difficult to keep my foot out of it, but it is one of the best vehicles I've ever owned... !
The only way I can conserve fuel with the flexible & fun 'Roo is to not drive it when I don't need the cargo carrying capability ...
