Rusty,

I use the Topsider on all my cars now. What I found that works the best is to eliminate all but an inch of the Tygon tubing that connects from the metal tube of the lid to the PVC tube that goes into the dipstick housing. Then I change the oil when it is hot so that it flows like water; it you did that with the Tygon tubing it would collapse. Typical oil change from start to finish on the Crossfire is 20 min, which includes topping off window washer fluid and checking air filters.
