Sierra 18-0003 0003 Disposable Oil Change Funnel

Changing oil on a boat or marine engine often turns into a slippery nightmare, especially in tight engine compartments where spills are inevitable. That's where the Sierra 18-0003 disposable oil change funnel shines—it's designed specifically for marine enthusiasts who want a hassle-free, mess-free experience every time.

Crafted from robust, oil-resistant paper materials, this funnel stands up to heavy viscosities like synthetic blends or thick diesel oils without buckling. Unlike flimsy plastic alternatives, it maintains its shape during the pour, directing every drop precisely into the fill tube. Once the job's done, simply crumple it up and toss it in the trash or recycling bin—no greasy cleanup or storage space required on your vessel.

Why Marine Mechanics and Boat Owners Love It

• Universal Compatibility: Fits any marine engine dipstick or fill port, from outboards to inboards, gas or diesel. No adapters needed for most setups.
• Spill Prevention: Wide mouth captures oil from the pan drain, while the tapered spout minimizes drips and overfills.
• Eco-Conscious Design: Biodegradable paper breaks down naturally, reducing plastic waste in marine environments where pollution hits hard.
• Space-Saver: Ultra-compact and lightweight, it stows easily in your tool kit or glove box, ready for impromptu maintenance.
• Cost-Effective: Single-use convenience means no repeated washing or risk of cross-contamination between oil types.

Pro Tips for Your Next Oil Change

To maximize efficiency, warm up the engine first so oil flows smoothly—this funnel's sturdy construction handles the heat without warping. Pair it with absorbent bilge pads for any minor drips, and always check your engine manual for capacity to avoid overflows. In salty marine air, it resists corrosion better than metal funnels, keeping your workspace pristine.

Boat owners report saving up to 30 minutes per change compared to traditional methods, turning a dreaded chore into a quick pit stop. Whether you're prepping for a fishing trip or seasonal haul-out, this funnel keeps your engine bay spotless and your focus on the water.
