Frequently Asked Questions

Q: Will this engine oil funnel fit my car's oil filler port?

A: This universal oil funnel is designed to fit any oil filling port with an inner diameter of 2.9 cm (1.14 inches) or larger, covering approximately 98% of cars, trucks, and SUVs on the market. If your vehicle has a standard-sized oil filler cap, this funnel should fit securely.

Q: How does the self-locking clamp work?

Q: Can this funnel be used for fluids other than engine oil?

A: While this funnel is specifically designed for engine oil changes, its funnel and chamber design makes it suitable for other automotive fluid top-ups such as transmission fluid or gear oil, provided the filler port size is compatible. Always clean the funnel between different fluid types to avoid contamination.
