What causes insufficient oil pressure in the Volkswagen EA888 engine?
1 Answers
Insufficient oil pressure in the Volkswagen EA888 engine is related to the oil pressure sensor located next to the oil filter, with one high-pressure and one low-pressure sensor. Low oil levels can lead to insufficient pressure. It's often difficult to determine whether the oil needs changing just by visual inspection or touch. Under normal driving conditions, if synthetic oil is used, it generally can be changed every 10,000 kilometers. When selecting engine oil, pay attention to the following four key factors: 1. Key Factor One: Choose oil based on the engine's requirements. There's no need to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. 2. Key Factor Two: Multi-grade oil is preferable as it is economical, long-lasting, and efficient, providing better protection for the engine. Due to the characteristics of multi-grade oil, it may appear darker or show lower oil pressure compared to conventional oil, which is normal. 3. Key Factor Three: Some domestic brand oils are of quite good quality and are much cheaper than their imported counterparts, making them a reliable choice. 4. Key Factor Four: If the engine is in good condition and the seasonal temperature is low, it's advisable to use oil with lower viscosity to ensure smooth oil flow. In high-temperature seasons or when the engine is severely worn, higher viscosity oil is beneficial for forming an oil film and reducing engine wear.
