Matched 1969 porsche 911 oil temp gauge and sender: The normal operating temperature of Shijie 911 engine oil is generally 70-90 ℃. If the speed is high, the temperature will be relatively high, reaching about 100-110 ℃. If it exceeds 120 ℃ for a long time, it should be checked. High oil temperature is a comprehensive fault.Cause of high oil temperature: coolant defect. The cooling radiator is blocked. Scale or dirt in the water tank will increase the flow resistance of the coolant. The fan belt is loose, resulting in insufficient cold air in the water tank. Loose water pump belt or corrosion of water pump impeller will reduce the coolant flow. The concentration of antifreeze coolant is too high. The thermostat failed, causing the temperature to rise, but it still couldn't be opened. There is empty gas in the cooling system. At this time, place the exhaust air switch in the exhaust air position.

Influence of engine oil temperature on vehicle driving: too low temperature is not conducive to combustion, thus affecting power; If the temperature is too high, it will be a great test for all parts of the engine, especially the oil seal and cushion. Therefore, it's best to control the oil temperature between 90-100 ℃ when using the car at ordinary times, and it doesn't matter if it's 100-110 ℃. One day, after intense driving, the temperature reached 120 ℃, but after a while, the temperature will fall back to normal driving state, which is no problem.The engine oil level can only be checked through the display in the instrument cluster. Any fault of the oil level gauge is displayed by a warning in the instrument cluster.

1. Requirements for correct oil level measurement

(1) The vehicle is parked horizontally.
(2) The engine is at operating temperature.
(3) The engine is at idle speed.

Porsche engine oil adopts 0w40 model. Because the engine operates efficiently, the internal temperature of the engine is very high during operation. Using high viscosity oil can better protect the engine and reduce the internal temperature of the engine.The quality of oil used in self-priming engine is general, and mineral oil and semi synthetic oil can be used. If the owner has a large budget, he can use fully synthetic engine oil. Compared with self-priming engine, turbocharged engine has more precise engine structure, more complex working conditions, higher requirements for oil quality, and requires lubricating oil with better fluidity, so it is best to use fully synthetic engine oil.
