Prefilling oil FILTER contamination

[Hootbro]

I am more worried about the kid shooting a snot rocket into my burger that is being made for me when eating out than any remote possibility of this issue and debris with a oil filter.

Dirt dropping from the periphery of the mounting base on the engine is greater risk, especially if the new filter gasket has has a slightly larger diameter than the previous one. People often wipe that area, but wiping can make matters worse, if not done carefully.

Universally sound advice.

Just so those of you with inverted oil filters don't feel left out:

I removed the large hanging burrs on my last 2 wix filters, then poured oil into the filter, always do and always will. Even horizontal mounted filters get a little oil to wet the filter element.
Evaluating other brands with better threads.

What some seem to over look is that oil filters have an anti drain back valve. Pre filling an oil filter is exactly the reason there is a valve. So the engine doesn't dry start. So saying you don't need to refill the oil filter is against the sole purpose of the ADBV.
And for the people that say, my filter mounts sideways, you can still fill it and let the oil absorb into the media. Same with cartridge filters.

Wipe the threads with a clean rag. Simple things are not hard.

That's what I do. Always have. Maybe I should make a video?

A lot of these ridiculous topics wouldn't exist if people looked at their manual.

I pre fill 100% of the time.

Even for upside down Subaru oil filters.

I never change my filter, so I don't have to worry about it. (Just kidding). I always pre-fill. I don't like hearing the bearings knocking until the filter fills up.

The possibility of being struck by a meteor in your bedroom is not 0 percent. Anything is possible.

^ LOL… given a long enough timeline, someone will take the extra minute to clean the housing/filter and a meteor will crash thru their garage and kill them when they they would have been in the clear if they had not

They could lock out all new posting to this forum for 5 years and 95% of it would still be relevant at the end of that 5 years.

I think the difference there is that the ADV prevents every start from having to refill an empty oil filter, rather than the far less frequent first start after an oil change.

 

[Dborch41]

I avoid the whole issue by simply motoring the engine for a few seconds using the clear flood mode before the first actual start. This will spin the pump long enough to fill the filter up without putting any significant load on the engine.

That's obvious. I'm making the point about prefilling.

Most people don't have that feature.

Nonsense.

You are screwing with threads a metal on metal interface. It generates wear particles, 100% certainty. Also certain: it doesn't matter. The particles are too small, too few to matter. There's residual oil on the filter spud that lubes the threads sufficiently-even if you "wipe it off" why a dry rag. You can't wipe off oil with a dry rag, you can only wipe off EXCESS oil, the film is still there.

 

[Dborch41]

Most people don't have that feature.

Nearly every EFI car has that feature.

Not my Toyota. Unless you are saying that holding the pedal down while starting is clear flood mode. I'd rather just fill the filter
