Last week, the price of petrol in India was €1.35 per litre on average. This is subject to change based the city you visit, time of year, and the country’s current economy. If you aren’t set on hiring a car in India, then consider Algeria. Petrol prices there are some of the cheapest in the world at €0.34 per litre as of last week. Hong Kong is another great place to visit and rent a car, but keep in mind that petrol prices can be expensive at around €3.06 per litre.
