Mixing mineral and synthetic oil: consequences
Share:

Can mineral water be mixed with synthetic?

Most drivers are convinced that mixing lubricants can harm the engine. There is also a completely different opinion, according to which mixing different oils does not threaten the engine. Car enthusiasts need to know which of these opinions is correct.

It is also necessary to understand how to distinguish mineral oil from synthetic. This will allow you to choose the right lubricant, which will ensure the smooth operation of the internal combustion engine.

Without car oil, the engine can be operated, but for a very short time. This will absolutely lead to the failure of the power unit. The purpose of engine oil is as follows:

  • Prevention of wear, jamming, and other malfunctions.
  • Reducing energy losses to a minimum.
  • Cleaning the engine.
  • Motor protection against overheating.
  • Reduction of noise and vibrations of gears, reduction of loads.
  • Mineral oil is made by direct processing of petroleum. It has changeable indicators, evaporates strongly.

    In order to improve its characteristics, various additives are used. They quickly destroy the structure of the lubricant, which is why it must be replaced frequently.

    Synthetics are made in a laboratory. With its synthesis, it is possible to set the desired indicators. The grease is characterized by stability, high viscosity and temperature characteristics. Do not add too many additives to it.

    Synthetics do not need to be changed as often as mineral water. It is more thermally stable, resistant to oxidation, evaporates little, and forms few carbon deposits.

    Any petroleum products, whether mineral or synthetic oils, contain certain additives, such as:

  • depressor;
  • anti-foam;
  • viscous;
  • cleansing;
  • reducing friction;
  • antiwear;
  • anti-corrosion;
  • antioxidant.

    It all depends on additives. If the additives are incompatible, do not pour the mixed product into the engine. It is better to buy a normal lubricant that is optimal for your motor.

    The effect of additives on the engine

    When mixing mineral water with synthetics, damage to the engine can be caused due to the combination of various additives. Mineral additives are meant. They simply cannot decompose in synthetics.

    It is difficult to determine what the consequences of using a blendable petroleum product will be.

    It is not recommended to use a mixture of lubricants.

    This can damage the internal combustion engine if the additives are incompatible. Additives that have not dissolved will settle in the power unit. It is likely that the oil receiver mesh will be closed, and therefore the engine will run out of oil.

    With such operation, the engine can break down very quickly. It must be remembered that the lubricant forms a special film on the contacting parts.

    Due to mixing of motor oils, the film is destroyed.

    As a result, engine wear is accelerated.

    Experts have found that if you mix lubricants with compatible additives, nothing bad will happen.

    But what should you do if you have already filled your engine with a mixture of oils with incompatible additives?

    The main thing is not to panic. At low speeds, take the car to a car service center. Its employees will carry out diagnostics and, if necessary, change the oil. You may just need to replace the oil filter. This way you can avoid serious damage to the engine.

    It is possible to operate a car with a mixed oil product poured into the engine, only for a short time. You should not take risks and mix different oils. Then the ICE will work for a long time.

    What is better - a synthetic or mineral product?

    Which oil is best?

    To answer this question, it is necessary to take into account certain factors, to remember how one type of lubricant differs from another.

    Synthetic oil has good fluidity

    First of all, read the manufacturer's recommendations. Read the owner's manual that came with your vehicle. It indicates which car oil should be poured in the summer, and which in the winter season. The optimum viscosity of the lubricant is also prescribed there.

    Also consider the degree of wear of the motor, the type of oil previously poured. For example, if you poured mineral water into the internal combustion engine for a long time, then the cracks that appeared in the rubber were filled with deposits.

    If synthetics are poured into such a power unit, it, due to its own washout and acidity indicators, will remove everything, including the necessary deposits. That is why situations so often happen when, when replacing a mineral oil with a synthetic oil, the latter pours out of the engine through cracks.

    Experts advise using a synthetic product in new engines, engines that operate in harsh conditions (for example, in sports cars). If you have an old car, you simply need to change the oil more often.

    Lubricant selection

    There is an intermediate option between mineral water and synthetics. This is a semi-synthetic motor oil. It is a hydrocracking product. Semi-synthetic consumables are cheaper than synthetic ones. In terms of characteristics, they are slightly worse than synthetics.

    When choosing an oil product, one must take into account the model of the car, its mileage, the condition of the engine, the type of fuel that burns in the internal combustion engine, and climatic conditions. Under normal conditions, car oil needs to be changed every ten thousand kilometers.

    Russian conditions are considered quite tough. Lubrication must be changed every five thousand kilometers. Diesel and turbocharged engines need frequent oil changes.

    Fill your engine with a high quality product. Buy products from well-known manufacturers that have a good reputation. It's sad, but today you can often find counterfeit petroleum products in stores.

    In order not to buy low-quality oil, you need to take a responsible approach to the choice of lubricant.
