oil pressure and temp in the same gauge

• 2024-03-28

The temperature of the oil pressure gauge is usually displayed on the instrument panel of the vehicle. It is usually a circular gauge with a pointer and dial on it, which will point to different numbers or scales to display oil pressure and temperature. Some vehicles may display two independent gauges, oil pressure and temperature, on the dashboard, while others may merge them into one instrument panel. In addition, some high-end vehicles may display detailed information such as oil pressure and temperature on the driver's infotainment screen. Regardless of the situation, the temperature display on the oil pressure gauge is usually easy to recognize and use, so that the driver can keep track of the vehicle's oil condition at any time.

What is the normal pressure of car oil

1. Most cars have engine oil pressures ranging from 2.5 to 3.5, which is a normal range. Idle speeds range from 2 to 2.5 pressures, and excessively high pressures can pose significant risks; If the pressure of car engine oil is too high, it will affect the fuel consumption. The high viscosity of high viscosity lubricating oil will increase the friction resistance between the surface layers of the components, increase power loss, and increase fuel consumption.

2. Secondly, it affects heat dissipation, as the viscosity of the lubricating oil is high, resulting in a slow circulation speed of the oil and a slow rate of heat removal, which can easily cause the engine to overheat; At the same time, the insufficient amount of engine oil may cause a decrease in the amount of oil pumped by the engine oil pump or the inability to pump oil due to air intake, which may also result in a decrease in engine oil pressure.

3. The impact of low engine oil pressure on automobiles: If lubricating oil with lower viscosity is used, the internal friction consumption of the oil can be reduced, while the wear of the components is not added; According to experiments, the viscosity of engine oil decreases by one level, and the fuel saving rate of the engine is 1-3%.

4. (Steam); The viscosity of lubricating oil that affects heat dissipation is high, and the circulation speed of the oil is also slow. The speed at which heat is taken away is also slow, which can easily cause the engine to overheat.

5. In addition, when the engine temperature is too high, it is easy to cause the engine oil to become thinner, causing a large amount of loss from the fit gap, which affects the decrease of oil pressure and the increase of engine oil pressure; Therefore, it is important not to casually assume that the higher the engine oil pressure, the better the guarantee for the vehicle. It is important not to choose high viscosity engine oil products for the sake of obtaining high engine oil pressure. It is recommended by the vehicle manufacturer to use lubricants with lower viscosity based on the temperature range during use, while ensuring lubrication.
