The title is a bit odd but my point is i'm looking at a university which is in cambridge approx 40 miles away from me but i want to commute as i don't want to live in halls. So my question is how much money would i be spending on petrol to drive approx 80 miles a day(there and back)
They call it PMS because Mad Cow Disease was already taken! :D
Depends on the car. At the moment, £10 should get you 80-110 miles in average cars. Bank on £10 for a return journey, anything less is a bonus. Unless you have an Impreza, and are getting 18-22mpg... then it'll cost you heaps more. Think I was getting 250-280 miles to £50 or thereabouts...
The car will be a fiat punto so it will probably have a 1.1 engine.
With no traffic, expect £7-£9 for each return journey, if the car is good and looked after properly. Get stuck in traffic, and forget any expectations. I reckon you'll use a litre in around 20 minutes of idling, so you'll waste a gallon every hour and a half of idling. It all adds up... Stopping and starting will use a bit more, too.
