Unlike other initialisms, which were invented and grown on the internet, “your mileage may vary” goes back to the 1970s and ’80s in the U.S. During that time, automobile manufacturers frequently promoted their estimated mileages to compete…However, due to the variations in driving conditions, they had no way of guaranteeing the exact mileage customers would actually get. Therefore, these ads would feature the disclaimer, “Your mileage may vary.”
