• Balanced diet with exercise would be those who use high octane gas; perform oil changes on schedule, using only high-quality products and changing the oil filter if necessary; rotate tire regularly, using top-quality radials; keep their air-filter clean, ensuring to replace it when necessary; periodically check for rust, and doing maintenance to prevent it; check their belts, and replace them when they show signs of wear; check other fluids, cables, etc., etc.

Which car would run better on the same amount of gas? Which car would get further?
