Review: Great product - It’s working well i tried it so many times ## Features - 【2 Seconds Fast Detect Engine Oil Quality】Engine oil tester can quickly measure engine oil transmittance and temperature in 2 seconds to determine whether engine oil needs to be replaced. It can help you check your engine oil regularly to ensure you are driving in a safe condition. Engine oil tester can help extend the life of your car.
