I prefer 5 qt jugs when I to get done fast with no mess and no fuss.
Since I got that cool funnel that attaches to the oil filler inlet, I'm an oil change wizard. I have not be able to overflow this funnel.
It does make me giggle to turn the jug up, completely up, and see it empty in seconds with no mess. If you have a Toyota you may wanna buy one of these funnels.
Only one trip to the trash can. No carrying six or seven qts out to the car.
I generally, if possible, buy a case of qts for simplicity sake. Most of "my" cars take between 6-7 qts. I add a jug and then add a qt.
