If you are able to fill the filter due to mounting, always do it. If it is mounted sideways or upside down, you don't have much choice.

Think about it. Most of you guys are pretty smart, so use your head. Oil goes from the pan, the pump, the filter, and then the rest of the engine. Any dead spaces in there will have to be filled before oil goes to the engine. That's a big filter. Why have a nearly 1 qt dead space if you can easily avoid it?

On the sideways ones I filled the filter until the element was what I thought was saturated. Which was I filled it up until the filter was topped off and quick drinking oil. Then I poured the oil back out into the bottle to at least the level of angle at which the filter was to be applied. Then I used my cat-like reflexes and master skill to screw the filter on without spilling a drop.

My thinking behind this was at the very least there was some oil in the filter and soaked in the element to be pulled through until the filter filled up completely. It did take an extra few minutes and probably sounds batty but just something I did. Not a clue if it was actually preventative, no skin off my teeth to do it.


I've never had anything with the filter upside down.

When I change the oil myself, I pre-fill.. The last change, I had a friend that owns an auto repair shop do it for me, and I have no idea if he pre-filled or not, but the truck is still running, so I don't worry about it.

Couldn't have said it better. Why not get rid of 1 quart of bearing seizing air and replace it with fresh cool oil? I fill mine.

Oh no! How do we get the oil out of the jug?!??!!!?!?????? Just be careful and thorough taking the foil off.



I've always prefilled the filter.
It drains through larger holes to the pan then is filtered before it get to small oil ports.

I always prefill. If you have the time, fill through the small holes, not the center. Small holes are supply and big center hole is return.

If it was a big deal, no filter would be mounted horizontal or upside down on a diesel or any motor.

Good idea to pre-fill, sure, simply makes sense.
Enough to worry about if you don't, I don't think so.

Out of thousand's of people that fill their oil filters one dummy makes a bad fill and this is should stop every one? I DON;T think SO ..I have done this from the age of 13 I am 70 and still fill my filters.

I pre-fill mine, always have, always will. It just makes sense to do it right. My manual also says to pre-fill the filter.
