How to Check Oil Level in Car
https://www.wikihow.com/Check-Oil-Level-in-Car
Mobil One and other oil manufacturers recommend checking engine oil levels before driving your vehicle, when the oil is still cold. However, some manufacturers will recommend checking the oil after you've warmed up the engine, so check your owner's manual to find the specific recommendations for your vehicle.[1] You want the oil to be in the oil pan, not in the engine as it will be while you're driving. Immediately after driving, the oil level will appear lower, making it easier to overfill the oil. If you want to check the oil and have been driving the vehicle, wait five or ten minutes to let it settle into the oil pan before checking it.
- In very cold weather, it may be appropriate to drive the car around a bit first to get the oil loosened up and less viscous before checking it. Let the engine run for a few minutes, then let it cool down for five before you check it.
- Many people disagree about whether or not the oil should be checked hot or cold. Some manufacturers recommend checking engine oil warm, and it's perfectly fine to do so as long as you're looking at the right line. There will appear to be "less" oil on the gauge when the oil is colder, but the oil will thin out as the vehicle runs up to normal operating temperature.
- Synthetic oil expands more when it is hot than "regular" oil does, so it may be best to check your oil cold if you use synthetic oil. Talk to your mechanic if you aren't sure.
