Wow, what a simple but great product to use! No matter how hard I try, I ALWAYS spill oil with a traditional funnel especially using a 5QT jug. This funnel makes it nearly impossible to spill since it's ******* into the oil cap. This funnel is not exactly cheap, but it's worth trying out.
Bought the top and bottom part of the funnel for our Tundra. Adding just the bottom for my Honda was great!
This funnel chamber fits great, it's tight and doesn't leak!
