Frequently asked questions
How often should I stop?
Every two hours or 100 miles is the standard advice for staying alert; the calculator adds that break time to your total automatically.
Why is my real MPG lower?
Speed, roof boxes, luggage weight and air conditioning all cut economy — above 70 mph, drag alone can cost 10–15%.
