How to Read the Oil Dipstick on a Volkswagen?

Introduction to reading the oil dipstick on a Volkswagen: When checking the car's oil dipstick, the vehicle should be parked on a level surface. Generally, as long as the oil level is between the upper and lower limits, it is considered normal. If the oil level exceeds the upper limit, it can increase the resistance of the engine crankshaft and lead to more carbon deposits. Conversely, if the oil level is below the lower limit, it can cause engine cylinder scuffing or bearing damage. Below are some precautions for oil usage: 1. Do not mix old and new oil. Old oil contains a large amount of oxidative substances, and mixing it with new oil will accelerate the oxidation and deterioration of the new oil, reducing its effectiveness and lifespan. 2. Do not mix oils of different brands or grades. Since different brands and grades of oil contain different chemical additives, these additives can sometimes react with each other, reducing lubrication effectiveness and producing acidic or alkaline compounds that accelerate corrosion of engine components. Mixing two types of lubricating oil can result in stratification, turbidity, and deterioration of cleaning performance.
Last time I helped my neighbor check the oil level in his Volkswagen Tiguan, I realized there's quite a technique to using the dipstick correctly. You must park the car on level ground and wait 10 minutes after turning off the engine to allow the oil to drain back. Pull out the dipstick, wipe it clean with a cloth, then fully reinsert it before pulling it out again to check the level. The oil mark should be between the MIN and MAX lines, ideally around the upper two-thirds position. If you notice the oil level is unusually high right after an oil change, it might mean the old oil wasn't fully drained. If it's below MIN accompanied by blue exhaust smoke, it's likely burning oil. Remember that older VW models with mechanical dipsticks require checking both sides of the stick, while newer models with electronic oil level indicators can display the reading on the infotainment screen - no more bending over or getting your hands dirty.
