Meet the OF1, our take on the vented oil funnel. Because we're apparently better at designing things than naming them, OF1 simply stands for Oil Funnel 1—and is not to be confused with that website.
This particular unit is designed to fit most M35x4 threaded engines from the likes of Mazda. If you look through the pictures, you'll see what we mean.
If you change your own oil—or do it for others—you've probably experienced the familiar "blub, blub, blub" as oil and displaced air fight over the same opening.
The OF1 is designed to fix that.
A dedicated vent allows air to escape while oil flows into the engine, giving you a faster, smoother, more controlled pour without the constant gulping of a traditional funnel.
We've also built in an anti-splash lip to help keep oil where it belongs and an anti-drip cap so you aren't leaving a trail of oil across the garage when you're done.
The OF1 is also available as a digital download, designed for PETG, ASA, ABS, Nylon, and PC blends. Recommended print settings are included, and the design has been tested across multiple printers and configurations.
Whether you're maintaining your own vehicle or regularly changing oil for others, the OF1 is a simple tool designed to make the job faster, cleaner, and less frustrating.
Less glugging. Less mess. Just pour.
