Damage from Cleaning the Air Filter with Compressed Air
In addition to the examples on the previous page, here we have 4 examples from vehicles using 10W-30. These four examples were run at the same time using the same oil.
These four samples were run to find what the problem was in 3 Nissans operating where the dealer cleaned the air filters during regular service. The fourth (first one shown) was my Toyota pickup that I changed for a control, even though it only had 5800 km on the oil. I use the pickup on mostly dirt roads, with heavy loads, and a lot of city stop-and-go. With a total of 152,000 km total mileage and 5800 on this oil, it only had 1 ppm of iron and 4 ppm of dirt. This was with a standard DENSO air filter, never cleaned.
El soplado del filtro, bajo cualquier cuidado, termina acabando con la vida útil del motor. En estos tres ejemplos, de más de 100 que tenemos, podemos ver los efectos en autos de individuos que están tratando de cuidar sus vehículos con los mitos tradicionales.
When we analyze this wear by each 1000 kilometers, we have:
- The Toyota Hi Lux without any cleaning of the filter had 0.17 ppm of iron per thousand km.
- The first Nissan X-Trail where the filter was cleaned had 34.15 ppm of iron for every thousand km.
- TheX-Trail has 200 times more wear. The engine was completely worn out in 50,000 miles.
