I usually just used a church key and a funnel. If you were careful, you didn't even need the funnel. The spouts were hard to stab into the can correctly and with the later fiber cans you had to be wary of crushing down the sides rather than piecing the metal top.
The plastic quart bottles seemed a great convenience when they came along, especially if you needed less than a full quart of oil.
I find it a little amusing that the labels of both the Kendall and Pennzoil 10W-40s tout their fuel savings. This might have been true as compared to the GTX 20W-50 to the left.
OTOH, many people back in the seventies swore by GTX 20W-50 and used it in everything.
