I Don’t Know If You’ve Tried, But Grasp The Actual Dipstick Just Above The Tube (Instead Of The Handle) And While Turning It Clockwise (Like You’re Screwing It In), “Feed” It Into The Tube. This Allows You To Push A Little Harder Without Kinking The Dipstick.
The reason some dipsticks have a “twisty” look is so that they can make compound bends in the tube. A regular, old-fashioned flat stick can only follow simple bends.
