Best Diesel Additive Holder for Your Truck Bed: Archoil and Hot Shot's EDT

If you run Archoil AR9100 or Hot Shot's Secret EDT in your diesel, you know these bottles don't fit neatly anywhere. Too big for a cupholder, awkward in a toolbox, and prone to leaking if they tip. Most diesel owners end up with them rolling around the cab floor or buried in the bed. There's a better setup.

Why Diesel Additive Storage Matters

Archoil AR9100 and Hot Shot's Secret EDT are not cheap. A 41.3oz bottle of Archoil runs $40-50. Hot Shot's EDT in the 2025+ long-neck 16oz bottle is in the same price range. These are products diesel owners use regularly and want accessible — not hunting for them every time they're at the pump.

The Magnetic Holder Option

Print Tweak Build makes dedicated magnetic holders for both the Archoil 41.3oz bottle and the Hot Shot's EDT 2025+ long-neck 16oz bottle. Same magnetic mounting system as the Mag Hitch Pro — rubber-coated neodymium magnets that grip your steel bed wall without drilling or permanent modification.

The Archoil Magnetic Holder 41.3oz uses four 150-lb magnets for a combined 600 lbs of holding force. That's not overkill — it's engineered for a full bottle of oil treatment bouncing around in a truck bed at highway speed. It also fits both the old and new Archoil bottle versions.

The Hot Shot's EDT Magnetic Holder is purpose-built for the 2025+ long-neck bottle design — the one that changed geometry from previous versions. It mounts the same way: press to bed wall, drop bottle in, done.

The Screw-Mount Option

Prefer a permanent install? Both the Archoil and Hot Shot's EDT holders are also available in screw-mount versions. Two mounting tabs, clean PETG body, rigid installation with no rattle. If your bed already has mounting hardware or you want a completely fixed setup, the screw-mount versions are the answer.
