The flex is amazing, just the right stiffness for a great angle approach.
I have 3 different vehicles that this fits. Generally speaking, I do all my own maintenance and I am far more particular than some hourly employee. This funnel does what it claims, add oil without spilling, and it is hands free. My cars burn nor leak any fluids, but my storage place for this funnel is with me in the trunk, just because.
I use it daily and it performs well.
Excellent for Eco engines, solves the problem of them overflowing from the oil cap
Fits perfectly in the oil fill tube. Don’t have to worry about the funnel falling over while adding oil. Definitely recommend it!!
