Lubricheck Motor Oil Tester - Instantly Know If Your Oil Needs Changing!

The Lubricheck can pay for itself in just one saved oil change! Like a "Blood Tester" for the oil in your car, truck, motorcycle, etc., the Lubricheck can help measure the health of your engine. A few drops of oil placed on the Lubricheck sensor from a dipstick can instantly tell you the condition of your oil and engine. Lubricheck 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 time to change. A rapid flashing 10 means you may have engine problems. Simply clean off the sensor with an absorbent rag, and you are ready for the next test. Now you can decide when to change your oil based on the facts! Over time, oil additives designed to neutralize acid build-up are depleted, and impurities build up in the oil. The Lubricheck uses a unique capacitive/resistive sensor to measure the levels of acid (related to TBN) and contamination from soot, dust, dirt, wear metals, fuel, water or antifreeze. Using the Lubricheck, many customers have discovered leaks in their cooling systems long before any permanent damage to their engine. By confidently rejecting the outdated, 60 year old advice to change oil every 3,000 to 5,000 miles, most users can easily cut motor oil use by over 50%. Designed and assembled in the USA. Patent pending. *Some specialty or extended use oils with high levels of additives, or with metals such as zinc or moly, may give falsely negative results. Examples include Amsoil Signature series, Redline, and non API Royal Purple oils.
