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.
