<<Well if you guys just have to have a funnel to get that oil in you can
make a quickie out of your junk mail by twisting a piece of 8.5 x 11"
plain writing paper into a funnel design.
Newspaper and other paper works too.
I've also notices that many gas stations have funnels made of paper like
the old Dixie cup drinking cups with the bottom point clipped to make
them into a funnel.>>

Back to basic's, any port in a storm Stanley.

I like the simplicity angle too.

No oil dripping funnels store.

I splurged and dropped a buck at the local farm supply store and wound
up with a 8" long necked polypropylene mini funnel that works great.

It stands up perfect with the license plate holder snapped up against
it, wedging it up against the rear hatch, for the perfect pour angle.

When all done it gets dropped into the plastic bag it came in, and back
under the seat.

It's the right size to accommodate the ATF filler tube too.

Not as simple as your method Stan , but close.
