One of the big annoyances amongst the British public is the rise in petrol prices, with fuel being on an alarming upward slope over the past few years. To fight back from such increases, some motorists have opted to generate their own fuel via used chip fat. There have been plenty of articles delving into this method and taking this into account, we’ll now look to clarify some of the common queries that are associated with the topic.

Is it really possible?

The myths happen to be true and it is certainly possible to use leftover oil in your fuel tank. However, it’s not simply a case of going to your local fish and chip shop, acquiring the oil and pouring it into your tank. The process is quite extensive, but can ultimately save you money.

There are two options motorists can follow. One involves converting the engine of the car; meaning that you will install a vegetable oil tank that will normally be placed in the boot of the car. You will also need to have separate fuel lines as contrary to popular belief, you won’t simply be replacing your existing fuel tank. Instead, this tank needs to be used during the early part of the journey when the oil is not at the required heat. Furthermore, you will need to filter any oil that goes into your tank, with this being performed both outside of the vehicle and via a device inside the tank for the ultimate effect.

The other option open to motorists is to ‘home-brew’ the oil. It would be fair to say that this is a much more risky option and if you don’t have any past experiences dabbling in science, it’s probably best to avoid it. You will need to acquire waste oil tanks on this website, and then perform several stages to make the oil suitable for use. This usually involves adding alcohol, leaving the oil to stand for around twelve hours, removing the by-product of the reaction, before then washing the oil again. Suffice to say, it is a cumbersome process and one that is certainly not recommended for beginners.

What cars are suitable to use this method?

Unfortunately, not every car is suitable to run on chip fat. In fact, only ones that run Diesel are eligible, and even then they have to be around 15 years old with a low specification.

How much does the used oil cost?

Unsurprisingly, the finances are the main reason why so many people are starting to turn to this method. While the average price of petrol seems to be pushing £1.35 per litre, used oil can usually be picked up for around 18p per litre. Admittedly, you’ve got to facilitate the initial costs on either converting your engine or processing the oil, but with prices starting at around £200 it can be a very effective way to save money.

Will I have to pay tax on it?

Another reason why the procedure is become more and more popular is because of a recent law change. Back in 2009, the government made changes so that anyone producing less than 2,500 litres of biofuels per year would be exempt of paying tax on it. With this equating to approximately 50 litres a week, which is a full tank for most vehicles, the majority of individuals will not have to pay a penny to the taxman.
