🔍 Smart Buying Tips for High-MPG Highway Cars

  1. Get hybrid and diesel check-ups. Diesel engines need proper DEF and emission upkeep, hybrids need healthy battery packs.
  2. Confirm emissions compliance. Especially important for older diesel models.
  3. Prefer private sellers with full service records. They often maintain filters and fluids meticulously.
  4. Plan for long-term savings. Even slightly higher maintenance is outweighed by years of lower fuel cost.
