【Why You Need Engine Oil Tester】Engine oil tester can help you check your engine oil regularly to ensure you are driving in a safe condition, helping to extend the life of your car. Failure to replace engine oil in time and poor quality oil will reduce lubrication, reduce sealing effect, reduce cooling effect, and reduce cleaning effect.

【2s Fast Oil Quality Detection】Engine oil tester can quickly measure oil transmittance in 2s to determine if there are impurities or metal powder, and whether engine oil needs to be replaced.The more impurities in engine oil, the lower the transmittance. To prevent impurities from settling and causing inaccurate measurements, pls make sure to shake up your used oil bottle before testing it. If you test the oil in the vehicle, run the engine for one minute to circulate the oil and then test it.

【Applicable to Various Engine Oils】Our engine oil quality tester is compatible with various lubricant oiI standards, suitable for most gasoline and diesel engine lubricant oil on the market. Separate sampling and measurement of gasoline engines and diesel engines can more accurately determine the health status of lubricant oil.

【Identifier & Sound Prompt】Engine oil analysis kit can generate a analog bar graph. When the engine oil transmittance is between 60% and 100%, the engine oil tester screen will display 'OK'. When oil transmittance is between 30% and 60%, an '！' will be displayed to remind you to pay attention. When oil transmittance is below 30%, engine oil quality tester will display '×' to warn you to change the engine oil to ensure safety.All three test results are accompanied by a‘beep’ sound to remind you.

【High-precision Sensor & 50inch Flexible Probe】Engine oil tester probe adopts an integrated high-precision photoelectric sensor and temperature sensor, which provides fast and sensitive response and more accurate measurement results. A 1270mm/50inches long hose probe can be bent flexibly to easily enter the dipstick hole. No need to take the oil out to test. The hose is made of PTFE material, which is highly resistant to oil, oxidation and corrosion, effectively extending its service life.

【2.8-inch LCD Display with Backlight】The engine oil analyzer is equipped with a large 2.8-inch high-definition LCD screen, which can intuitively display the engine oil transmittance and temperature, allowing you to view the test results at a glance. The engine oil tester has a backlit button that can be turned on with one click to adapt to changing usage scenarios. No matter under bright daylight or dim nighttime, you can read the data clearly and work efficiently.

【Auto Power Off & User-friendly Handheld Design】If the engine oil tester is in a state of no operation, it will automatically power off after 5 minutes to help you save power. It is powered by 4pcs 1.5V AAA batteries(included). Engine oil quality tester is lightweight, and its handheld portion has a non-slip silicone design that provides excellent grip and facilitates one-handed operation.

【Warmly Note】1. Please check the temperature displayed on the dashboard of your car before testing. The engine temperature must be below 60°C during the test. 2. Please wipe the test probe clean before testing, and make sure the probe is immersed in oil during testing. 3. The depth of the engine of different models is different. If the tester probe cannot be immersed in the oil, please take out the engine oil for testing.
