How long does one 200g gel last?

Longevity depends on cabin size, ventilation, and scent preference. Most drivers get several weeks of noticeable fragrance from a single gel. Place it in direct airflow (like near a vent) for faster distribution, or tuck it under a seat for slower, steadier release.

Will this gel spill if I place it in a cup holder?

Gel formula is stable and won't leak under normal driving. Still, place it in a holder or secured spot to avoid rolling around during hard braking or turns.

Can I use this on the dashboard or windshield?

Stick to cup holders, door pockets, under seats, or vents. Gel residue on the dash or windshield can be difficult to clean and may leave marks on the glass.
