Misfuelling and pumping your diesel car with petrol fuel can be a very costly mistake. Although there may not be any noticeable changes to your car initially, as the petrol makes its way to the fuel system you will have serious consequences. Depending on how far the petrol has circulated through the fuel system and engine, the cost of repairs can vary from a simple drain and flush to some very expensive component replacements.

2.Check your tyres

Low tyre pressure will cause your tyres to drag on the ground and consume more fuel than fully pumped-up tyres.

3.Letting your fuel run on empty

Letting your car run on low fuel isn’t a crime, but any careless or dangerous driving caused by the lack of fuel could see you punished by law. You could face a £100 fine and three points on your licence if you are forced to stop in the road and cause an obstruction to other motorists.

4.Overfilling your tank

While overfilling the tank can be tempting and seem like a way to save additional trips back to the pump, you will actually end up paying more for your fuel. Filling the tank beyond maximum capacity can cause the fuel to overflow and waste money. Overflowing fuel can also fall to the ground which causes a potential fire hazard and you will still be charged for the waste.

In order to find the lowest prices, head to a petrol station early in the morning or later in the evening. can help people save on everyday bills plus niche products like gadget, temporary car and courier insurance.
