Simply take off the oil cap and lock this funnel into place. No more poor fitting oil funnels, that you have to try and hold while your dumping oil in. Works great for setting 5 QT oil jugs in their to fully drain. The funnel's base is modeled to the same pattern that locks the oil filler cap into place.
Select your engine type to ensure you get the correct fitment for your truck.
These funnels are made from PETG-CF (Polyethylene Terephthalate Glycol Carbon Fiber), which is resistant to oils and most chemicals (except Acetone), so you don't have to worry about any deterioration. Super strong construction with a great finish.
