To last longer, your engine must always have the proper level of oil. As you drive, some amount of oil is consumed and the oil level drops. As a result, the friction increases and the engine wears faster. By checking the oil level, you can catch if it’s getting low early and top it up. You also can see how dirty your oil is and if it’s time for an oil change. First, check your owner’s manual, as it contains the proper instructions and safety precautions. Your engine needs to be warmed up and the car should be parked on a level spot. Here, we used the V6 Toyota Camry as an example.
How to read the oil dipstick. Examples:
|In this car, oil looks clean and the oil level is FULL. Good job; keep driving.|
|Here, the level is okay, but oil looks dirty. It’s a good idea to have the oil change done soon.|
|This oil is very dirty and the level is below the LOW mark. It’s time to change your oil.|
|This oil looks a bit dirty and the level is low. You may want to top it up. If it’s been a while since your last oil change, consider booking an appointment for your next oil change.|
How to top up the oil level
|To top up, use the same grade oil as you already have in the engine. The required oil grade (e.g. 5W-20, 0W-20 or 5W-30) is usually marked on the engine oil cap or you can find it in your owner’s manual. Make sure to use synthetic oil if the owner’s manual specifies so. In most cases, the owner’s manual has the reference how much oil needs to be added to bring the level from ‘Low’ to ‘Full’.|
|For example, according to the owner’s manual, in this V6 Toyota Camry it takes 1.6 qt to bring the level from ‘Low’ to ‘Full’. Add a small amount, wait a minute to let it flow down, then recheck the level. If it’s still low, repeat; but don’t overfill. Use a funnel to avoid spills. Another option is to visit your dealer or repair shop and have them top up your oil for you.|
Why does your engine need the proper level of oil?
The engine oil has two functions: it lubricates moving parts and helps dissipate the heat produced by combustion. The lubrication function is especially important. For example, the crankshaft, which is the engine main rotating part, makes on average 3.1 million revolutions per month of driving, yet it is only separated from the non-moving parts by a very thin layer of oil (around 0.0012 in or 0.03 mm) that is supplied under pressure. Oil also lubricates pistons moving up and down in the cylinders as well as all other moving parts of the engine.
