Do you pre-fill your oil filter housing?

Same thing I thought! Growing up on a farm, we did lots of oil changes and maintenance. I know for a fact that oil filter technology has changed drastically over the years, and with the filter it's about 'microns'. My wife has been involved in making filters for 23yrs. @ Cummins filtration, when talking with engineers, they have changed 'media'(oil filter innerds) over the years to allow the smallest of particles to be filtered, so knocking those particles off the engine internals either suspending them or filtering them seems to be the norm. I totally agree though that it seems once the particles are drained off, collected in a 'pan', lets drain 'em!

 

How did my comment not have anything to do with yours? You're the one who brought up shorter OCI's as a comparison to prefilling filters. Likening prefilling filters to shorter OCI's is laughable at best.

 

I did not compare shorter oil change intervals to prefilling a filter. I brought up people spending time and money on “cheap insurance” while not doing something else that’s free insurance. Neither one is necessary, but what’s the logic behind paying to do one while not taking a few seconds to do the other for free.

 

I do not pre-fill and here are the results after 5 changes.
