Review on Lisle 19802 Threaded Oil/Transmission Funnel: Hassle-Free Pouring and Precision Funneling by Adam Shuler

I have only used this funnel for oil but it does everything a funnel is supposed to do. Yes, there are some applications where this funnel will not fit in the filler hole, but guess what? It's still a funnel and it will still do what it's supposed to do. I personally use this product 5-10 times a day at work and prefer it over standard funnels as the outlet is much larger than regular funnels which means more liquid. can get where it needs to be in less time. Yes, it's plastic and if you try to tie it with the wrong thread pattern, the threads will get tangled. So quick summary 1) it's a funnel, higher flow than standard funnel 2) it has flows for some applications 3) if you use it wrong you can mess up the flows. 4) When #3 happens you still get a pretty good funnel.
