The effectiveness of a good maintenance plan
In these samples we can see the savings in wear and hours between oil changes created by improving the maintenance plan, buying better oils and filters.
These are four examples of agricultural tractors that operate in the worst dust conditions.
The first example covers more than 2000 hours of work. The first sample (at the bottom of the report) is a brazilian oil. It has 280 hours of work on it and 60 ppm of iron wear, with 16 ppm of dust. They changed the air filter, and the third sample has 350 hours with only 3 ppm of dust and 10 ppm of iron wear. This is a reduction of 21 ppm of iron from every 100 hours of use to 3 ppm per 100 hours, multiplying the engine life by 7 times.
The real result shows up in the last sample (on top) where between the new air filter and the good oil, they only have 4 ppm of wear metals in 300 hours of use. In this period of 1800 hours, they were able to reduce the wear metals from 7.2 ppm per 100 hours to 1.3 ppm per 100 hours, increasing the engine life 6 times.
