The last 45 days have been unpleasant, weather-wise. There was a night of freezing rain, which annihilated my gas mileage. The ice was too thick for my scraper, so it took about 20 minutes to defrost. It was still raining when the ice melted, and I ended up having the caravan run for 30-35 minutes while driving only 2 miles.
Due to various reasons (cold weather, limited income, high gas prices), the caravan only takes short trips, which doesn't allow the engine to warm up for efficient mileage. The South Dakota winters make for cold starts. I have been thinking about installing an engine block heater to rectify this problem.
194.3 miles / 12.14 gallons = 16 mpg.
