What's with the "glug jugs" that Pennzoil/Quaker State is using these days? I can't seem to pour into a funnel without making a mess with these [censored] designed jugs. Anyone else notice this???
Hold them on their side (label facing up) and it will pour properly. It's probably because you are holding it parallel to the handle. I use QS regularly in my dads van and I know exactly what you are talking about...
If you dump them quickly, they will "glug-glug" and spill. You can either hold it horizontally as mentioned above or pour it vertically like you are but not as fast. You are not allowing air to flow in as the oil flows out.
Hold them or anything else upside down, so the outlet is on top. Pour slowly enough that there is a little room for air to enter at the top. The horizontal works almost as good
