Specification Operating Temperature: -10°C~60°C Operating Voltage: 6V Power Supply: 4pcs 1.5V AAA batteries (included) The more impurities or metal powder in engine oil, the lower the transmittance. To prevent impurities from settling and causing inaccurate measurements,pls shake up your used oil bottle before testing it. If you test the oil in vehicle,run the engine for one minute to circulate oil and then test it. NOTE 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. Some models do not have an oil caliper so the probe cannot be inserted for testing, and the oil also needs to be taken out for testing. Simple Operation Buttons Made of natural rubber User-friendly Handheld Design Non-slip silicone Auto Power Off If the engine oil tester is in a state of no operation, it will automatically shut down after 5 minutes to help you save power. Battery Compartment 4pc * 1.5V AAA batteries (included) Note: The probe should be wiped clean before each measurement and the temperature of the engine must be below 60°C. Review: Worked Spot On For Me! - My car oil life tracking indicated 30% left. Car's user manual recommendation is to change oil at 7500 miles and I was at 5000 miles currently. Rather than wait until oil life dips further down, I went ahead and replaced oil and filter ahead of schedule. I then decided to purchase this oil tester detector and tried it out on the old oil which I saved in a 5 gallon oil jug. The tester registered 30% too! I was impressed. The car and this oil tester appear to be using a similar way to determine oil life. I'm sold! Review: Autool oil analizer - Muy buen producto ## Features - 【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.
