How to Measure Engine Oil in Older 5 Series Models?

Slowly pull out the dipstick and check the oil mark on it. If the oil mark is between the maximum and minimum levels, it indicates the oil is within the normal range. The oil level can also be checked in the i-Drive system. Push down the toggle on the turn signal stalk until the "OIL" indicator appears, then press the "BC" button on the turn signal stalk to view the oil dipstick.
Measuring the oil level in an older 5 Series requires careful attention to detail. Personally, I make sure to park the car on perfectly level ground, then wait about ten minutes after turning off the engine to let the oil fully drain back into the oil pan. Next, I pull out the dipstick, wipe it clean, reinsert it all the way, and then slowly pull it out to check. The dipstick has two marked lines, and the normal oil level should be between them. If it's close to the lower line, it's time to add some oil. Once, I was in a hurry and checked it after less than five minutes, which showed low oil level and almost led to overfilling. Older cars are prone to burning oil, so I recommend checking it like this every month. Always keep the same type of oil in the trunk and top it up when needed. Don't wait until the engine warning light comes on, as that might mean damage has already occurred.
