When using methane, the car does not lose much in acceleration dynamics compared to driving on gasoline. However, you don’t expect easy and fast overtaking on the highway from an ordinary Largus. It feels like acceleration to 100 km/h in Largus on methane lasts a couple of seconds longer than in the gasoline version. Official manufacturer data: 14.4 seconds on methane and 13.4 seconds on gasoline. Contrary to the myth that exists among motorists, there are no differences in the ratio of crankshaft revolutions and vehicle speed when using different fuels. And it cannot be. The engine spins up to 3000 rpm at a speed of almost 120 km/h. Of course, when overtaking on the highway, no, no, and you’ll switch to a lower gear. In this case, the gas mixture begins to be enriched with gasoline. This is done to reduce the thermal effect on the engine. In addition, the engine always starts on gasoline. It is these two modes of operation of the power unit that add several rubles spent on gasoline to the cost of a kilometer of travel on methane.

Fuel consumption
During the trip, the car was operated in “highway” mode, close to mixed. Yes, the route was mostly intercity, but it is also worth taking into account the settlements that we had to visit. In addition, there were many sections along the way where the road was being repaired (in the Penza and Ryazan regions).

Methane prices in our country vary from 14 to 16 rubles per cubic meter. m. |
We managed to drive 295 kilometers on methane before switching to gasoline. The cost per kilometer was almost 1 ruble. For comparison, in a similar mode, Largus consumes about 8 liters of gasoline per hundred. With the cost of gasoline being 42 rubles per liter of 92, each kilometer of the journey will cost 3 rubles.

If gas consumption is too high
If the problem was discovered immediately after installation, then the reason is often hidden in a defective gas equipment; if several years after successful operation, then the prerequisites were frequent system breakdowns or maintenance by unqualified technicians. 4th generation gas equipment is characterized by low fuel consumption due to the optimization of its supply by an intelligent electronic system.
WHY METHANE AND NOT PROPANE. I’ll explain so you don’t torment me with advice.
This is not the first time I’ve heard that propane could have been installed cheaper, there would have been more space in the trunk, etc. As a rule, those who are not in the know advise. People! I gave myself all these arguments more than once while I was deciding what to install: METHANE or PROPANE. Well, we are not so rich that we can buy something more expensive out of idleness. And not so economical that without noticing the real benefit, you quickly grab something that is inexpensive. I’ll say right away that in all my cars, except diesel and Japanese right-hand drive, I had propane everywhere. The last Volga had fourth generation Italian equipment. And when I worked in a taxi, there was methane in my owner’s cars. So I knew what it was about.
Methane outweighed, and why? I'll tell you in order. You and I live in a country where everyone strives to deceive their neighbor, and at every step. Comparing with the last Volga, I can give an example of how I was repeatedly filled with 53-55 liters of gas into a 50-liter cylinder, this is the easiest prank of the tankers. But sometimes they fill it with something unknown, after which, in the best case, the gas filters are changed, and in the worst case, all the rubber membranes are completely replaced, not counting the downtime of the technician. Plus, propane consumption is with a coefficient of 1.2 compared to gasoline, and for methane it is 0.8-0.9 (exclusively from the words of the master). Those. Propane consumption is more than gasoline, and methane consumption is slightly less. And they use chemicals because propane is a liquefied gas, and methane is compressed; it is also not so demanding on cold starts. Again, at the time of my thoughts, gasoline cost 25 rubles, propane 16 rubles, and methane 8 rubles. And therefore, when consuming 12-13 liters of gasoline in the city in the summer and with the climate, we get 25 * 12 = 300 rubles / 100 km = 3 rubles / 1 km and even more. On propane, taking into account that the consumption is higher than on gasoline: 13 * 16 = 208 rubles / 100 km = 2 rubles / 1 km. And on methane, even 12 * 8 = 96 rubles / 100 km, in fact it’s really less. Here's the whole layout: 3-2-1. I can’t explain it any simpler or more accessible. From these figures, anyone can understand that savings on propane are 1 ruble/1 km, and on methane 2 rubles/1 km. Considering that gasoline has become more expensive, the difference is even greater. True, propane has become a little cheaper. Based on this, upon reflection, I calculated that if the latest generation propane costs approximately 20,000 rubles, and methane 40,000 rubles, then they will pay for themselves in the same 20,000 km. True, I now have an increase in price due to the added cylinder, so it will pay off in 30,000 km. It even makes sense to re-borrow money; it still pays off quickly.
And therefore: I don’t need any advice, that I could just stuff in a “bagel” and everyone would be happy! I consciously went for it, because... We load the trunk only during long trips into nature. But I don’t carry bags around the place and around the city. This means that if we need to load a lot three or four times a year, then somehow we’ll make room and fit in. But the remaining 360 days a year, I can very comfortably transport myself or, for example, my daughter to school and back. At this time, it doesn’t matter to us how much space there is in the trunk! After all, people drive Matiz cars and they like them, but they didn’t even make a trunk there at the factory.
That's who needs propane, please. And I am satisfied with everything, but at the same time I am in no way imposing my opinion, but simply sharing my impressions. Good luck on the road!
My car park! • Require topping up
| Methane consumption per 100 kilometers - comparison with propane and gasoline The main reasons for high wholesale prices for liquefied hydrocarbon gases are a reduction in supply volumes under direct contracts for February for some producers by 30, a high level of export quotations, a reduction in refining against the background of a decrease in oil production under the OPEC agreement , RTS Vice President Rinat Fattakhov commented to Kommersant. And for methane, these figures reach 11353 kcal kg and 8210 kcal per liter of production, as a result of which consumption rates fluctuate in the ratio 85-93. |
Comparison of methane consumption with gasoline • Therefore, every liter counts, even better if you managed to save it.
Cost of installing gas equipment and fuel
Installing gas equipment allows you to significantly save money due to the low cost of fuel (gas is almost 2 times cheaper than gasoline).
Let's give an example. Let's say you drive 100,000 km per year. With a gasoline consumption of 10 liters per 100 km, gas consumption will be approximately 10% more, for a total of 11 liters of gas per 100 km. The price of gasoline in 2022 is 43.5 rubles/l, propane 21 rubles/l, methane 15 m3/l.
| Gas type | Fuel price | Average installation cost for 4 cylinders | Monthly savings | Annual Savings |
| Propane | 21 rub./l. | 27,000 rub. | RUB 16,930 | RUR 203,185 |
| Methane | 15 rub./m3 | 60,000 rub. | RUB 22,410 | 269,000 rub. |
Why is it profitable to fill your car with gas - Cost of issue
| Methane as an alternative fuel for trucks. characteristics. Because of this pressure, most likely there are not many gas stations, in our city of up to 1 million residents, there is only 1 gas station and it’s oh, how inconvenient it is to drive to. In addition, methane vessels are only cylindrical in shape, which can make it difficult to choose a place for installation and take up the useful volume of the luggage compartment. |
Conclusion • In terms of cost in the long term, after the installation of gas equipment pays off, methane provides high savings on fuel relative to propane;.
Methane as an alternative fuel for trucks. characteristics.
More and more commercial vehicles began to appear on gas (namely Methane). but nowhere have I found an understandable scheme for calculating the efficiency of this gas in comparison with diesel. a little about gas (no matter what they write here about propane) https://ru.wikipedia.org
Compressed natural gas (compressed natural gas) is compressed natural gas used as a motor fuel instead of gasoline, diesel fuel and propane.
. It is cheaper than traditional fuel, and the greenhouse effect caused by its combustion products is less compared to conventional fuels, so it is safer for the environment. Compressed natural gas is produced by compressing natural gas in compressor units. Storage and transportation of compressed natural gas takes place in special gas storage tanks under a pressure of 200-220 bar. Biogas is also added to compressed natural gas, which reduces carbon emissions into the atmosphere.
Compressed natural gas as a fuel has a number of advantages: * Methane (the main component of natural gas) is lighter than air and in the event of an emergency spill it quickly evaporates, unlike heavier propane, which accumulates in natural and artificial depressions and creates the risk of explosion. * Non-toxic in low concentrations; * Does not cause corrosion of metals. * Compressed natural gas is cheaper than any petroleum fuel, including diesel, but exceeds them in calorie content. * Low boiling point ensures complete evaporation of natural gas at the lowest ambient temperatures. * Natural gas burns almost completely and does not leave soot, which worsens the environment and reduces efficiency. The exhaust flue gases do not contain sulfur impurities and do not destroy the metal of the chimney. from me
