When should i change the air filter ?

[chiapet]

Had a 2002 Silverado and the gauge NEVER moved. Always changed every 6 months along with wipers. Lots of pollen/dust and rain in Florida.

The link I posted was Donaldson nonsense. Here's one of their videos. At the 1:33 mark, it explains how new filters can expose the engine to more contaminants:

 

... and here's some CAT nonsense (see page 24, 4th paragraph down in the left column): http://albahar.com/wp-content/uploads/2014/09/SEBU9208-00.pdf CAT even developed a line of filters around the phenomenon: https://parts.cat.com/wcs-static/pdfs/PEHP6028-04.pdf

 

 

... and some Cummins nonsense: https://www.cumminsfiltration.com/html/en/training/faq/air.html

 

 

So if they're correct that a filter is least efficient at stopping particulates when it's new, then changing to a new filter more often would expose the engine to more contaminants than just leaving one in for whatever service life they recommend.

 

Whatever. It's your truck - change it whenever makes you happy.
