This ENGINE OIL TESTER can help pay for itself with just one saved oil change! Akin to a "Blood Tester" for the oil in your car, truck, motorcycle, etc., it can assist in measuring the health of your engine. By placing a few drops of oil from the dipstick onto the sensor, you can instantly determine the condition of your oil and engine.

How does this engine oil tester work? The tester primarily reacts to the increase in acidity of oil. As the oil degrades, it becomes more acidic and starts to pit metal engine parts. The red LED #10 reading usually indicates that the level of acid in the oil has reached a maximum acceptable level, and the oil should be changed. However, other contaminants such as dirt, soot, water, antifreeze, and metal particles can also influence the reading. Water and antifreeze in the oil may signify a bad seal or head gasket, while metal particles could result from unusual wear of bearings, pistons, rings, etc. Excessive carbon or soot may be caused by poor compression or excessive blow-by. Fuel leaking can dilute the oil and may cause an artificially good oil quality reading. If test results show that the oil does not deteriorate as expected over time or seems to improve, check the engine for fuel leaks (try a drop of oil on paper and look for a gray ring). If a significantly worse oil rating than expected is displayed, we recommend having the engine checked or sending a sample to an oil laboratory for analysis.

This ENGINE OIL TESTER works on trucks, tractors, boats, mowers, ATVs, motorcycles, or any gas or diesel four-stroke engine. The results are displayed by lighting LEDs ranging from 1 to 10 - Green (1-7) means your oil is good, yellow (8-9) means fair, and red (10) means it's time to change. A rapid flashing 10 may indicate engine problems.
