Also, keep in mind that, at any time really, whether the engine is running or not (although I'd only do it with it off), you can open your air box, look at the filter, even pop it out and check it, without worrying about all the air falling out of the engine. It's easy to check, and doesn't really take much work. Try doing that with an oil filter. Oil gets everywhere, you generally have to jack the car up, and you can't really look INSIDE of it without cutting it open. Takes more work.

Plus, the air filter tells you what's going IN to the engine. The oil filter gives you a clue as to what WAS in the engine.

^ Air filters are a little easier to inspect, and you can put them back in if they’re not bad-would need mad welding skills to do that with an oil filter!

I just changed my 2010 Hyundai Elantra air cleaner filter at 52,000 miles. The vehicle is still under warranty for the powertrain. It had been changed at the dealer once already some time before 30,000. I replaced it with a WIX 49070 air filter.

I service lotsa friends cars. Air filters seem to be neglected.
I vacuum and reinstall them and tell the owner to get a new one, or I hit Amazon.
Cabin air filters are even worse.

Ill admit I changed my cabin filter at about 120k on my Mazda. I leave air filters in usually at least 30k it was too long on the cabin filter 4 sure. Was pretty bad.

Guess you haven't seen the photos of filters that have caught a lot of crud. If you want to run no oil filter, then by all means do so. grin2

Not true of cartridge filters---although inspection might involve spilling a little oil..

A few years ago, I changed the blower motor in a friend's HHR. The cabin air filter was plugged. One can easily conclude the plugged filter is a huge factor in why the blower motor failed. IIRC the HHR had less than 100,000 miles on it.

Even if an oil filter looks "clean" visually, there can be lots of microscopic particles trapped in the media. Particles that you can't see with the naked eyes can cause engine wear. Basic logic is the cleaner the oil, the less engine wear. Just like with air filters - the cleaner the air going into the engine, the less engine wear.

I have the K&N air filters on the Honda and the Ford F-150 and I clean them every 6 months or when needed. I know most of the oil guys don't like them but I drove a 2005 Ford F-150 4x4 super crew Lariat for 215,000 miles with the K&N and it didn't use any oil. As far as I know the guy I sold it to still has it and it is probably at 240,000 miles or more and still going strong. I keep a very careful eye on the air filter as well.
