Engine oil is designed to lubricate a car engine. Only an engine lubricated with the correct oil will reach its full life. The engine and oil must be completely consistent with each other, so when choosing, you need to pay attention only to the manufacturer's recommendations, and not to advertisements or advice from the seller.
Instructions
Step 1
Study the operating instructions for your car, it will definitely indicate the oil that the manufacturer recommends to use. If you bought a car hand-held and you do not have an operating manual or service book, you can find out about the recommended oils on the manufacturer's website or at a service center specializing in your car brand. Remember that the automaker has many car models and they are equipped with different engines, so you need to know the recommendations for your particular car.
Step 2
The manufacturer rarely recommends a specific oil model; from the operating instructions, you simply learn about the specification and tolerance for oils for a particular engine. Based on this information, you should select the oil.
Step 3
Based on the manufacturer's oil tolerances for your motor, you can select oils that meet these tolerances. After that, choose from the resulting list the oil that suits you in terms of composition and viscosity.
Step 4
Motor oils can be synthetic, semi-synthetic and mineral. Mineral oil has a high viscosity and never leaks from the engine, it is recommended to use it for old worn out engines. Synthetic oil is more expensive, it works for a long time without replacement, is insensitive to low temperatures and overheating. Choose semi-synthetic oil if you have a new car, but you do not want to overpay for synthetic oil.
Step 5
The ease of starting the engine at different temperatures depends on the viscosity of the oil. Distinguish between off-season, winter and summer oil. It is obvious that summer oil is used in warm weather, and in cold - winter, off-season oil is universal. It is necessary to choose oil by viscosity in accordance with the following principle - the older the engine, the more viscous the oil should be used. Usually, the viscosity of the oil is indicated according to the American classification of oils - SAE. In accordance with it, oil of classes A2-96, A3-96, A5-2002 is suitable for passenger cars.
