I bring this up once in a while because I never ceased to be amazed aat
how many people don't know.

Adding oil to the engine is an aggravating challenge - trying to pour
oil into the filler neck at a near horizontal angle. You are guaranteed
to spill some oil and make a mess unless you use a funnel. Then
afterwards there is always the question of what to do with the funnel
which is now coated with residual oil.

The secret - the oil filler neck has an extension telescoped down inside
the filler tube. Just grasp the edge of the filler tube between finger
and thumb and pull and it slides right out, The rest is self evident.
Pretty slick.

Enjoy your cleaner rear.
