The nicest car I've ever owned, she remains nearly stock to avoid reliability problems. Regularly returns mileage in the 40s. For now I calculate my mileage by driving until it's as close to empty as I'm comfortable with and trying to get it filled up consistently.
Passenger mirror, radio antenna and windshield wipers/squirters removed, Mobil 1 0-30 Advanced Fuel Economy full synthetic oil.
Full synthetic oil for the transaxle, synthetic grease for the wheel bearings, permanent color matched lower grille block, color matched clip/screw-on rear wheel skirts, full underbody cover, pizza pan wheels and super narrow LRR tires, Scangauge II...... more as I think of them
