LPG: when LPG is cheaper in 2015?

Arates 14-02-2018 Auto
Driving cost you a lot of money every year. And with the ever-fluctuating but generally rising fuel prices, is a frequently asked question with which fuel you are out of the cheapest. Unfortunately walk the answers you often hear regularly diverge significantly. That's because you can look at different ways and every situation is different and car. Think of weight, fuel consumption, maintenance costs and depreciation. In this article we will explain everything closely and we give concrete examples of calculations, so you get exactly clear or LPG is a good option for you.

What things determine the cost?

Driving costs money. A lot of money when you add up all the costs you spend a year in your car. The main addition to the purchase, of course, fuel costs, road tax, insurance and maintenance. In particular, the first two are of great importance in choosing a particular type of fuel. However, a comparison is not always as simple. In addition, you can hear often contradictory claims about what mileage you advantageous at a given fuel can drive.
So the question when petrol or diesel is cheaper is very popular. But the same question also applies to LPG Unlike the choice of petrol / diesel LPG has few real benefits, in addition to low fuel. So when LPG the question is when it is off, so even more important.

Why is the number of kilometers per year?

How many kilometers you have to drive is based on the fact that you paid a low road tax on gasoline, but a high price per liter. For LPG and diesel is just the opposite. The relationship between them is what matters in determining which fuel is cheapest for you. It is important that the height of the road tax depends on the weight of the car. The heavier the car, the higher road tax.
G3 or regular LPG installation?
What you should know is that the government makes a distinction between environmentally friendly G3 gas installations and other gas installations. The difference is clearly visible in road tax. For a car of 1200 kilograms, you pay in South Holland in the case of G3 a monthly tax of 72 euros. It is an ordinary gas installation, however, you pay 110 euros. That is a whopping 50% extra! As the cars are heavier, the relative gap is narrowing. So G3 becomes less cheap, with heavier cars. However, there remains a significant difference.
This difference between G3 and other LPG, we go into the rest of this article from a G3 system. Firstly, almost all LPG installations from 1995 a G3 system. In addition, it is not to go for the hand for a more expensive non-G3 car, when you want just looking for an economical solution. G3 is always cheaper than other LPG cars.

How do you calculate the costs and compare your LPG with gasoline?

To display the number of annual mileage, whereby LPG is cheaper, we have to assume a number of things. First, of course, the price you pay for a liter of fuel. In addition, the road tax is an important component. The third aspect is the consumption. So the number of kilometers you can drive on a gallon.
Fuel price
The fuel price is independent of the car, state, or whatever. But of course the price varies seen over time. This is mainly due to fluctuations in the oil price. This makes it somewhat difficult to compare because the tipping therefore shifts back and forth. We're going out on the recommended retail prices from April 2015:
  • Euro 95 ?? 1,689
  • Diesel ?? 1.347
  • LPG ?? 0.827

The consumption of LPG is higher than gasoline. Usually about 15%. So that number, we can just use it to determine the difference in cost. We do not exactly know what is the fuel consumption of a particular car on petrol or LPG. Would you compare with diesel, then you will need to know the actual fuel consumption. So have to look at a certain type of car, so as to work with concrete numbers.
Road Tax
The amount of the tax is mainly dependent on the weight of the car. In addition, the exact amounts for each province somewhat different. These differences are not very big, so we go from here to the rates that apply in South Holland. These are:

Calculate the real cost

With the foregoing information, it is easy to calculate, if gasoline or LPG is cheaper. It is easiest to calculate this for a whole year. The unknown factor is now how heavy the cars that you want to compare. We are going in the other examples from the LPG variant is always a weight class higher than the gasoline car. This is because an LPG car, with additional gas tank is heavier. In practice it does not always have to be so that the car indeed opens a class higher, so there you need to keep an eye on extra.
The table below shows a number of different weight classes, see the annual costs for petrol and LPG:

LPG is almost always cheaper?

As you can see with bad LPG 10,000 km per year cheaper. That might not be what you would expect, but based on road tax and fuel costs LPG is indeed very soon cheaper. Compare you to a petrol car in the class of 1351 kg - 1450 kg with a car on gas in a heavier class, the turning point is very close to 7500 km / year. That this is not the whole story, it will be clear. After all, why else do you hear are said so often that you at least double or even three times as many kilometers per year or have to drive in order to justify the choice of LPG?

Other cost items that are of interest

Road tax, fuel costs and insurance are not the only factors that play a role in the cost. However, it is the most obvious and most practical aspects. But in the field of conversion, depreciation and maintenance, there are also differences. But the tricky part is that it does not leave so easily quantified. We call them right here for completeness, so you can take them into your consideration. And when you have a specific car in mind, you might find a more concrete show.
Maintenance costs for vehicles on LPG are usually higher

How much is the maintenance of a car on LPG?

That maintenance costs on average higher for a car gas, is certain. But how exactly is hard to say. Anyway it really varies by car model and engine type. You consider switching to LPG, then you would be wise to spend some time on the Internet. There is a lot of information about experiences with certain brands and models on gas. And it seems that some engines are many more suitable than others. So you can a lot of trouble and associated costs, when you're right in front of a car is known as suitable for LPG.

Depreciation in a car on gas

Due to the higher wear and tear on the engine block, not only are the higher cost of maintenance. The depreciation is therefore higher. An engine that has run between one hundred and two hundred thousand kilometers to be often revised. That's a hefty expense and can cost just two to three thousand euro.
Such revision has not taken place, the car will be less in demand and have thus longer amortized. The block or reconditioned, you just myself who incur additional costs. The exact depreciation is very situation dependent.

Depreciation and maintenance included in the calculation

So if you want honest compared with gasoline, then you will have to take the depreciation and maintenance costs in the calculations. However, it is not so easy to choose a certain amount here. Importantly, depreciation is a one-off and recurring maintenance cost. These amounts can vary widely depending on the situation, and that is partly why you often hear such contradictory noises about running on gas.

Calculation with additional maintenance and depreciation

We will have to make some assumptions so we can still bring these costs into the equation. For the yearly maintenance we estimate 200 euros extra compared to gasoline. In terms of depreciation is a bit trickier, because the exact amount is very dependable, but also because the depreciation is a one time fee. That amount is to be distributed over all the years that you will be driving in the car. We will take an additional write-off of 2 000 euro and this will amortize over four years, so we have an annual additional cost of 500 euros.
Now is the overview at 10,000 kilometers is as follows:
As you can see, there is effectively 700 euros in costs per year were added when driving on LPG. With this cost, it is clear that 10 000 km / year is not enough to switch from petrol to LPG. But without depreciation and only additional maintenance, LPG is in lighter cars are still cheaper.
Looking at an annual distance driven of 20,000 kilometers, it looks like this:
For completeness, we also give the amount at 25,000 kilometers per year:
Here you see that such a large number of kilometers per year, LPG always cheaper suits. Even with the substantial additional cost of 500 euro and 200 euro depreciation maintenance per year.


LPG can certainly less costly. For many people it is still one exciting transition because of the negative comments about LPG have ever heard. To what extent these advantages or disadvantages for you are important, you have to decide. In terms of cost, it is clear in any case that you should always go for a G3 installation, when you choose LPG.
In the examples above, you can easily determine if you drive enough kilometers a year, to save money by going for a car with gas. You should also do, especially because the additional depreciation may be a determining factor. And this is very dependent on the car you buy and how long you want to drive in it.
