Oil Analysis On Extended Change Interval

The pages below show the content of the engine oil on a customers car during an attempt to establish a mileage interval for change using a synthetic oiul made by Lubrication Engineers. We thought the results were quite interesting. The customer is a sales rep for the company manufacturing that particular oil. We do not use the oil, nor recommend an interval as long as this. The study showed his interval to be 25000 miles before change was indicated. He does change the filter every 3000 miles and tops off the oil level at that time. At this time his car has 300000 miles on it with no oil related failures. Lubrication engineers supplies oils mainly for industrial applications. This is another example of the benefits of synthetic oils.
