never. if it was important, the engineers would never build an engine with an upside down, or sideways filter.

my new tacoma has a canister, so that isn't happening

That has been my reasoning for not worrying about filling the filter. If it's a vertical or horizontal filter I pour some oil in it while I'm lubing the gasket, but I don't obsess over it.

Just did the BMW. FYI, these lights are amazing when working in the engine bay and under the car. Engine bay just loop zip ties to the hood latch loops our sheetmetal holes. They are very bright but not blinding and flood an area well. Just finished a complete cooling system refresh on the car and they were indispensable to seeing everything underneath the car clearly.

I want to agree with the logic but bean counters and poor engineering and built in obsolescence all conspire to build whatever is cheapest and easiest that will last some pre-defined time that "puts the blame on the consumer" for failure rather than the mfg.

We stopped listening to our ancestors who warned us of great floods and fires and famine the same way we stopped listening to our mechanics and plumbers and electricians

we take the engineers word as gold while we dismiss the people that actually DO THE WORK

I've changed thousands of oil filters, never filled a single one them.

My Harley's is horizontal so not gonna happen.

I've had a pressure relief valve stick closed on my old BMW a number of times.
I have no problem leaving them empty.
When you see how fast a full displacement pump can pump out 3 or more quarts of oil you quickly realize the bearings aren't going to see much more than one revolution of the crank before they're swimming in oil.

Seeing how 1/2 my cars have an oil filter pointing up, and 1/2 my cars have a filter pointing down, I'm taking the Dali Lama approach to this.....

(edit...oh... and there's a certain 911 with a filter pointing sideways) :)

So, it’s my understanding that the oil in large marine application engines are not changed, but filtered and analyzed for specific additive content…. The oil filters used are no where near the low tier that is used in automotive applications…

I couldn’t get your link to work, but would be interested in it. I was working on the 911 this afternoon/evening, changing fluids and wondered about a decent work light. I have a LED that attaches to DeWalt batteries, several headlight lights, rechargeable magnetic base LED lights, etc. It seems having a variety of lights is the way to go, because I can’t find a one light does it all.

Edit: I changed the oil but did not fill the oil filter in the 911.
