  1. First make sure your engine is off (no matter which temperature you’re after).
  2. Open your hood and find the dipstick.

  4. Reinsert the dipstick into its tube.
  5. Pull the dipstick out again and check the oil level, looking at both sides.

Why do you check oil when its cold?

Ray: The main reason for this is that when the engine is cold, all of the oil has had a chance to drip down from the top of the engine and settle in the oil pan, where it’s measured by the dipstick. That way, you’re getting a true and accurate reading of exactly how much oil resides in the engine.

Can you check your oil after driving?

Check your car’s parked on level ground, as a slope might give an inaccurate oil reading. Your engine should be cool. If you’ve just driven your car, wait for 5-10 minutes before you check your oil level, or check it first thing before you use the car.

Can I add oil to a hot engine?

You can put oil in your car when the engine is hot. Check the oil level after the engine has cooled, but it is safe to add oil to your car if it is warm or slightly hot, provided it has been turned off for several minutes. Be sure to avoid overfilling the oil past the “max” line on the dipstick.

What should oil look like on a dipstick?

So, let’s take a close look at the oil on the dipstick. The oil should look smooth and glossy and somewhat transparent. If it has sludgy deposits or grainy particles of dirt, it’s time for an oil change. The same is true if the oil looks too thick, is too dark (opaque), and/or has a putrid rotten-cheese smell.

Where should the oil level be on the dipstick?

At the base of the dipstick, there are two marks or small holes indicating the high and low levels of engine oil. The oil level should be between these two marks. Both too high and too low are bad for the car.

If you just add oil to your car’s engine periodically, that’s far better than letting your car run out of oil, but you’re still going to create a lot of problems if that’s all you do. If that’s the case, you’re likely keeping the same oil filter in the engine, too. So that’s never being replaced.

What happens if engine oil gets too hot?

A car’s internal heat could cause a chemical reaction in the motor oil, which in turn causes the oil’s viscosity to change, making thermal breakdown among the most damaging effects. If your vehicle’s engine warms up beyond a certain temperature threshold, the motor oil will degrade.

How often should you check oil?

You should check your car’s oil at least once a month to make sure that there’s enough oil and that it isn’t contaminated. Oil reduces the friction in your engine and keeps it running smoothly.
