To start I would like to note that the level of oil in the engine of any vehicle should be checked not less than once per week, regardless of weather conditions. This test, first of all, the key to a proper smooth running of your engine and car in General.
Prepare to check the engine oil, funnel and cloth. To check you need to take the oil that you poured into your car.
Put your car on a flat surface. It is important that when checking the oil machine was not at an angle. Look around the engine dipstick. Usually is a small plastic knob that is on the outside. Look like a small flattened needle.
Check the oil level till the start of the motor. In any case it is impossible to determine the oil level when the engine was running, as it is dangerous for your life, you can apolitica a jet of boiling oil, which apparently squirts off the motor. Additionally, you cannot check the engine oil immediately after switching off the power, as in this case it is impossible to accurately determine the fluid level, because it will be in a fluidized state.
Remove the dipstick and wipe it carefully with a napkin prepared. Lower back in the hole where he was. This must be done repeatedly to ensure that readings were accurate, because when you drive a car constantly is tilted and, consequently, the oil level is unstable.
Remove the needle from the hole and look for marks that it has. Top notch (MAX) – oil level motor max. Average notch (MID) – the oil level is close to half. Lower notch LOW - minimum oil level. If the liquid is at the upper or medium cut-off – all right, you can continue to drive. If the oil level dropped to a lower point – the oil must be topped up.
Remember to top up the oil should be of the type that you used initially, that is, if you have been flooded mineral (mineral) oil, refill, it is the same if you had used polysynthetic (semisintetic) or synthetic (sintetic), then it is important to add the same accordingly. In addition it is best to apply each time the oil is the same brand as the engines of the cars are different, and in some cases a mixture of oil the engine can't handle it.
If you need to add oil, gently open the tube, which is located on the engine cover, insert it in the hole prepared by the lake, not dripping oil on the engine, pour 1-1,5 liters, and then tightly close the tube, again check using the dipstick, the oil level and wipe clean the engine so it does not remain drops.
In the rest of the full quality control of the oils produced in special laboratories according to established procedures in accordance with existing standards. During the test determines the kinematic viscosity at 100 degrees C, flash point, mechanical impurities content, the presence of water, base number, dispersal ability (the ability to retain impurities) and the content of wear elements. When testing must take into account the total operating time of the vehicle during the entire period of operation, its mileage, engine oil consumption, engine failure.
Effectiveness of oils is reduced in the process of operation of the engine in mind altering their chemical properties. So, cease the effect of additives, oxidation of oil, the accumulation of impurities. Change viscosity, base number, etc. When you reach the limits of these indicators of oil is subject to mandatory replacement. It is worth to mention is to determine the quality of the oil on the eyes or the color is almost impossible. For example, in the case of buying a used vehicle specialists definitely recommended to replace the oil to avoid possible trouble.
