My wife has planned a cross country trip with her elderly father in his 2003 Volkswagen Golf (diesel) which gets 50 miles per gallon which he is quite proud of.
He is upset because my wife wants to bring along a Koolatron 12V cooler which draws 4.3 amps. Never mind that she’s paying for the fuel.
Can anyone translate the power usage to fuel consumption for me?
Like what is this going to cost for 5000 miles in terms of fuel volume or more specifically in miles lost per gallon?
