What is the normal engine oil temperature in summer?
2 Answers
An engine oil temperature of 100 degrees is normal, as the working temperature of engine oil typically ranges between 70 to 90 degrees. Below is relevant information about automotive engine oil: Functions of engine oil: Alleviate friction and high temperatures, reduce gas leakage, prevent external contaminants, protect against contact between water, air, acidic harmful gases and components, cushion the rising pressure in engine cylinder ports, and clean dirt generated on component surfaces. Introduction to engine oil: Engine oil, also known as engine lubricant, serves to lubricate and reduce wear in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. It is often referred to as the 'blood' of a car. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricants, determining their fundamental properties, while additives compensate for and enhance the shortcomings of the base oil, imparting new characteristics, making them an essential part of lubricants.
I've been driving for decades, and in summer, the oil temperature usually stays between 90 to 110 degrees Celsius, which is the ideal range. During long-distance drives or city traffic jams, the temperature might rise to 120, but if it consistently exceeds 120, you need to pay attention. I remember one summer on the highway when the temperature gauge shot up to 125, and I immediately pulled over to check, only to find the cooling fan was stuck. High temperatures thin out the oil, reducing its lubricating effectiveness and making engine components more prone to wear. In severe cases, it can even lead to engine seizure. You need to be extra careful when driving in summer—use digital gauges to monitor the temperature regularly and switch to full synthetic oil, which handles heat better. Also, make sure the coolant is topped up and the radiator is clean. These small habits can help you avoid major repairs, saving both money and hassle.
