Why Does New Engine Oil Have a Bad Smell?
1 Answers
New engine oil having a bad smell may indicate the use of counterfeit or inferior products. Precautions for adding engine oil are as follows: 1. Choose engine oil based on the requirements of the engine. Do not use high-grade oil in lower-grade engines or low-grade oil in high-grade engines; select oil that matches the engine. 2. Multi-grade oil should be preferred. Multi-grade oil offers advantages such as fuel economy, long service life, and high efficiency, providing better protection for the engine. 3. The oil level should be slightly below the mark on the dipstick and not overfilled. Excessive oil not only increases the rotational resistance of the crankshaft but also reduces the engine's output power. Moreover, excess oil can enter the combustion chamber and participate in combustion, leading to oil burning, blue smoke emissions, and increased fuel consumption. 4. Select oil with different viscosities based on the engine's operating condition. If the engine is in good condition and the seasonal temperature is low, use oil with lower viscosity. If the engine is severely worn and the seasonal temperature is high, opt for higher viscosity oil. 5. Always drain the existing oil completely and clean the lubrication system thoroughly before adding new oil to avoid mixing different types.
