do you check oil when the car is running

Popping the hood to check your oil is one of the most fundamental acts of car care. It’s a quick and easy way to monitor your engine’s health and ensure it stays properly lubricated. But a common point of confusion for many drivers is the correct procedure for this simple task. Specifically, the question often arises: do you check oil when the car is running?

Getting this step right is more important than you might think. Checking your oil incorrectly can lead to an inaccurate reading, which could mean you end up with too much or too little oil in your engine. Both scenarios can cause serious and expensive damage over time. Let’s clear up the confusion and get you checking your oil with confidence.

The Correct Answer to “Do You Check Oil When the Car is Running?”

The simple and crucial answer is no. You should never check your oil with the engine running. When your engine is on, oil is being pumped throughout the entire system. This means the oil pan, where your dipstick measures the level, is not holding all the engine’s oil. Checking it at this point will give you a falsely low reading. For an accurate measurement, the engine needs to be off and has had a few minutes to allow all the oil to drain back down into the oil pan.

The Safe and Simple Way to Check Your Oil

To get a true reading, follow these easy steps. First, ensure your car is parked on a level surface. Turn the engine off and let it sit for about 5-10 minutes. This waiting period is essential for the oil to settle. Then, pop the hood, locate the dipstick (usually with a yellow or orange handle), and pull it out. Wipe it clean with a rag or paper towel, fully reinsert it, and then pull it out again to get your reading. The oil level should be between the two marked lines or within the cross-hatched area.

What to Look For on the Dipstick

When you pull that dipstick out for the final reading, you’re looking for two things: level and condition. The level, as mentioned, should be between the minimum and maximum marks. It’s ideal to keep it close to the full mark. Just as important is the oil’s appearance. Fresh oil is a translucent amber color. If it looks thick, black, and gritty, it’s a sign that it’s time for an oil change. If it has a milky, frothy look, that could indicate a more serious issue, like a coolant leak, and you should have a mechanic inspect it.

By turning off your engine and allowing it to rest, you ensure you get a clear and accurate picture of your engine’s vital lubricant. Making this a regular part of your monthly maintenance routine is a small habit that pays off with a healthier, longer-lasting engine.
