You guys (or girls) on here that work on this newer stuff every day, my hat's off to you.

Read somewhere about a cartridge,oil and filter all in one.
Flip a lever, pop out used oil and filter and snap in a new one. Done. Can you imagine the price tag on that??
I bought a big weed trimmer on wheels, 6.5 hp briggs. Manual says oil never needs changing.
States how and it can be done but is unnecessary. I will be changing it.
