How to save money on petrol - Part II

Following on from my previous post (see below), here are some more great tips on how to save money on your petrol and diesel expenses and make running your car that little bit cheaper.

2. Be smart when you fill up

When you fill up your car, you are charged by the amount of petrol or diesel that passes through the pump.  Usually, when you stop filling up, there is still a small amount of fuel left in the tube that connects the nozzle to the pump.  Make sure that you shake every last drop out of the pipe and nozzle before you hang it up.  After all, you'll be paying for it.

Another tip is to try and fill up in the early morning or late evening, especially during the summer.  Fuel is charged for by volume, but it expands as it warms up.  This means that you may actually get less fuel for your money when it's warmer, than when it's cold.  By filling up at cooler times of day, you can ensure that you get the greatest possible amount of fuel (by mass, which is what counts in your engine) for your money.

The quality of the petrol or diesel that you put into you car can make a significant difference to how efficiently it runs.  Basically, the better the quality of the fuel, the further you will be able to drive on a single tank.  Following on from this, many people have advocated filling up at petrol stations that have a lot of custom.  If you buy your fuel from a petrol station that is not used very much, the petrol or diesel that you buy may have been sitting in the station's storage tank for quite a while.  During this time it can collect impurities and sediment, all of which can pass into your car and reduce its efficiency.  By buying your fuel from frequently-used petrol stations you can help to ensure that only the purest and cleanest fuel goes into your car.

Finally, there's no point in being super smart at the pump, if you've driven out of your way to reach it.  Try to fill up when you are passing a petrol station anyway, and don't make a special journey to get there - you'll only be wasting your fuel!
