Test you oil save money
This thing is great. Was going to change oil in my car but use this tester first. Tester showed the oil was still 70% good save on $140 oil change.

Results of % readings.
This item is not accurate on the reading results, several owner operators of commercial vehicles order this item and all of us got the same results. Tested item on a brand new bucket of oil, and the result was 100%. Tested the item on used oil and results were 20%. Then went to tested again on the same brand new oil and the results were 90%. I return the item and waited 6 weeks for them to send me a new one, as soon as I opened it did the sales test , tested on a brand new bucket of oil results were 100%. Then tested it on a used oil out of the truck oil type Melbac diesel oil super 1300 for heavy duty truck. With 7676 Miles into it the results were 20%. Then came back and tested on the same bucket of oil and the results were 20%. I will never buy this item again, and I don’t recommend it.

Tener una forma de conocer el estado del aceite es invaluable
Me agrada la idea de tener una forma de conocer el estado real del aceite.

Überzeugt sehr
Am Anfang wqr ich doch recht skeptisch - nur nach ein paar Tests hat mich der Tester überzeugt. Bei weniger als 100 % sollte man das Öl tauschen.

Funcionamiento.
Perfecto. Lo tengo desde hace 1 año y meses. Lo he probado en bastantes coches y funciona de maravilla. Cuidado hay que tomas las medidas siempre que el aceite este a menos de 35 grados Cº. De lo contrario lo que indique la pantalla no será lo correcto. POR LO QUE VALE LO AMORTIZAS EN 2 REVISIONES DE CAMBIO DE ACEITE.
