We manufacture refrigerators in Nashville, TN. The petroleum crisis has raised the price of gasoline to $3.75 for regular and diesel to $4.35 per gallon. In January, they were $3.00 and $3.50 respectively. Diesel engines get about 30% better mileage than gasoline engines.  We are considering acquiring and running our own trucks to deliver our refrigerators to the wholesalers in the future.
