Fuel Saving Tips
Many cars engage A/C in modes that are not clearly marked as such. For instance, in late 90s Ford Escort A/C compressor is engaged, and A/C turns on above 10°C (50°F) in all modes except [only panel] or [only feet] modes. Read your owners manual to make sure you only turn on A/C when you need it.
