How to properly test your car’s oil level
Ultra1Plus on Oct 26th 2025
Regularly checking the oil level in your car is one of the most important parts of car maintenance. We are able to complete this really easy task on our own. The procedure is always the same, regardless of the brand or model of your vehicle.
How to prepare your car for an oil level check
Every automobile has an oil reservoir dipstick, though some more recent models may use the onboard computer to notify you when the oil is low. Curious about how long motor oil lasts before it needs replacement? We break down the factors that determine oil longevity and effectiveness.
1. Make sure the automobile is on a level surface
Make sure the automobile is on a level surface and that the engine is off and cold before opening the hood to find the dipstick.
The expansion of materials or the angle of the oil tank will cause the oil levels shown to be higher than they actually are if the car is tilted or the engine is hot, making you waste time on the test. Once you've made sure the automobile is positioned correctly, you can open the hood and find the dipstick. Before your next oil change, find out how much motor oil you need based on your engine size and manufacturer recommendations.
2. Take off the dipstick's screw
It is easily recognized since it is typically brightly colored to set it apart from other engine components. Take off the dipstick's screw and wipe it down with a paper or towel. Before re-entering the dipstick, look for two marks on the bottom: one that indicates the minimum oil level the engine needs and another that indicates the maximum.
The dipstick should be carefully removed and reinserted to prevent tampering with the sample, now that it is clean and well-known to you.
The handle should always be above the tip, ideally horizontal. The tip of the dipstick should be above the handle; otherwise, oil might spill, resulting in a reading higher than the actual level.

3. Check if your car’s oil level is within the recommended limits
Without dripping (you can use your free hand to hold a cloth or paper a few centimeters below the dipstick), check if your car’s oil level is within the recommended limits. If it's low, simply add some oil, and if it's high, we recommend visiting a mechanic to have the excess removed. Understanding motor oil viscosity is key to choosing the right lubricant for your vehicle, especially when driving in extreme temperatures.
How often should you check the oil level?
During routine inspections or when passing an MOT (Ministry of Transport or another public institution) test, the oil will be checked, but it's recommended to check it once a month, with the change of seasons, or before starting a long trip.
Regular maintenance is essential, learn when to change your motor oil to extend your engine’s life and improve performance.
It is crucial to ensure that the oil levels are within the recommended range, as driving without sufficient oil causes the engine parts to lose their protective layer, leading to excessive friction and high temperatures that can seize or damage the engine.
