oil vs non oiled cai

[Vyrus]

The main advantage to the oil-less filters is the lack of maintainance and possible MAF problems. They filter equally well as oiled-filters in most cases (read: not better, equally), and they last usually 15-30k miles. I've switched to an Apexi dry filter on my Maxima just for convenience sake, maybe when the AFE is due for a cleaning I will slap on a similar dry-flow.

Too little oil and you'll have the top end of your engine blasted by the dirt that gets through. This shows up on oil analysis as elevated Si.

Too much and you foul the sensors.

Why doesn't anyone make big paper cone filters?

Question: How much experience do you have with oiled filters? There is no need to do anything to the filter for the first 50,000 miles. They are very easy to clean and risk of damage from over oiling is greatly exaggerated.

And the MAF sensor is easily cleaned with simple alcohol, if you are concerned about potential contamination.

I've been running oiled gauze filters for over twenty years on all sorts of vehicles. I've never had a MAF fouled. I've never had any engine trouble. One truck is a dedicated off-road CJ-5 used in very heavy dirt and dust with the same filter for over 10 years. Another truck is an F-250 diesel with over 450,000 miles. Numerous others over the years. My Armada has a drop in K&N and at 24,000 miles has not needed cleaning yet. Oil stays clean.

There are a lot of myths out there about this issue. All I can say is that there are a lot of serious off-roaders doing endurance racing with oiled gauze filters and a lot of diesel work trucks putting on very high mileage with these filters.

Nothing wrong with paper. And there is another thread here pointing out that the silicon content on oil tested in our very trucks shows that oiled gauze filters do not produce a higher silicon content.
