Transferring cars from gasoline to gas became popular 30 years ago, and then no one wondered whether special oils and additional additives were needed.
Gasoline is a high-calorie fuel that provides maximum engine power. Gas has a lower calorific value, so the engine power per gas will be less than that of gasoline. And the temperature in the combustion chambers of gasoline and gas is different. Less gasoline, higher gasoline. This results in local overheating of valves, seats, cylinder tops and pistons. The engine oil is also heated to higher temperatures on gas. But there are also pleasant moments. Gas contains much fewer sulfur compounds than gasoline and does not contain any aromatic hydrocarbons. That is, the acids from the combustion of fuel are less and do not require oil with a high reserve of alkalinity to neutralize acidic combustion products. All these features make it possible to formulate requirements for engine oil, which is optimally suited for cars, whose engines run on gas most of the time. The oil must be heat-resistant to withstand high temperatures for a long time, as well as have reduced alkalinity. High alkalinity is simply not necessary, and a high ash content of alkaline oils, on the contrary, can lead to increased engine wear. That is, low ash oils with high flash points and good high-temperature stability are needed for gas operation. Reminds you of nothing? These are the kind of oils that are required for modern diesel engines with particulate filters. Thus, for a modern gas engine, there is no need to develop any special lubricant, everything has already been done. That is why the whole line of low-ash oils produced by Liqui Moly GmbH - the line of Tor Tes, received recommendations for use in gas engines.
Automobile additives are special technical compositions reminiscent of grease, which are poured together with the oil in the engine or together with the gasoline in the gas tank. Their use brings a lot of positive changes in the engine and the car in general.
The following engine additives are identified:
- Restorative. Their task is to restore the condition of the engine components with high mileage. Such compositions are recommended to be used when mileage exceeds 300 000 km, but when the car is not maintained in good faith, oil additives are used earlier. They are versatile: improve engine performance, save up to 5% of fuel, improve traction.
- Fuel-saving. Additives with the composition of components that clean the surfaces of fuel system parts. Their use is important because the performance and driving characteristics of the machine are often impaired by simple contamination of the parts. Such additives are used no more than 1-2 times a year.
- Stabilizing (antismoke) additives. These compositions are used to preserve oil properties at critical temperatures. Their effect is to reduce the amount of soot and oil losses, cleaning and maintenance of valves and combustion chambers of the engine. Remember, the use of a stabilization additive in the engine oil is a measure that is only relevant in the case of periodic soot formation. Otherwise, a major overhaul is not necessary.
Different engines and car systems require different additives, clarify the need for the use of a particular composition by qualified craftsmen.
Finding a quality additive for gasoline engine and diesel fuel is not all you need to do to improve your car's performance. It is important to properly prepare the engine for the use of these formulations.
The list of activities includes:
1. Cleaning and rinsing the engine and replacing filters.
2. After filling the additive, leave the machine idle for up to half an hour. This is done to ensure that the composition is not an ass in the crankcase, but spread throughout the system, forming a protective layer.
3. It is forbidden to change oil for the next 2000 km. For the final action of the additive, it must be in the system for some time.
4. It is possible to fix the positive effect by double pouring. After 100 km of run after the first portion, the second one is filled. Most manufacturers indicate on the packaging of the additive the optimal way to use the compound.
At the Car City service center, you will receive a detailed consultation on the necessity of using additives in your case and the optimal variant of the composition.
We use compositions from well-known world manufacturers:
1. Additives Liquid Moli. This manufacturer produces various consumables for automotive equipment. Liquid Moli has been operating in the automotive market for more than 60 years, their experience can be trusted.
2. Hado additives. A company with a shorter history. They often offer cheaper solutions, but the quality and effect of their products do not deteriorate. Hado's gasoline additives and engines are able to compete with more established brands.
