I have just read it is very bad to clean air filter with compressed air

I didn't know it before, and I clean my truck air filter like that...

Sodium may come from salt used on roads, as the air filter is just behind the front right wheel.

I find it amazing that the TBN is so high after so many km's when the staring TBN for this oil is 15.5

This oil is designed for high sulfur diesel, but now we have 10 ppm sulfur diesel since 2008. It may explain that.

I used it to see how many years I can keep it in the sump as the truck don't run a lot.
