1. No-Spill 1415 Multi-Use Funnel: Best Overall
In our evaluation, the No-Spill 1415 stands out for its flexible rubber body that adapts to different filler neck shapes, reducing the chance of spills. Owner feedback consistently praises its built-in vent that allows air to escape, enabling a smooth, continuous pour. The compact size makes it convenient for emergency storage.
However, this funnel is designed primarily for standard gasoline nozzles and may not fit larger diesel pump nozzles. If you need a funnel for both fuel types, consider a wider model. Some users also noted that the rubber can be slightly sticky when new, but this improves with use.
- Flexible rubber construction conforms to various filler necks
- Built-in vent prevents glugging and back-splash
- Compact design stores easily in trunk or glove box
Pros: Excellent spill prevention; Very durable material
Cons: Not suitable for diesel nozzles (too small)
2. Hopkins 10305 GoFlo Fuel Funnel: Best for Diesel
The Hopkins 10305 GoFlo is a favorite among diesel vehicle owners because of its large opening that accommodates bulky diesel nozzles. We compared its specifications with others and found the 12-inch hose provides excellent reach for deep or angled filler necks. Owner reviews highlight its reliable seal and minimal spillage during use.
One limitation is that the flexible hose may kink if you force it into a tight bend, which can restrict flow. Some users recommend storing it without tight coils to maintain shape. It is also bulkier than simpler funnels, so it takes up more trunk space.
- Wide opening fits diesel and gas nozzles
- Flexible hose reaches deep filler necks
- Comes with a storage cap to keep clean
Pros: Versatile for both diesel and gasoline; Long hose for difficult access
Cons: Hose can kink if bent sharply
3. ARKSEN 1 Liter Oil and Fuel Funnel: Best Budget
The ARKSEN 1 Liter funnel is a budget-friendly option that delivers solid performance for occasional use. We researched owner feedback and found that the removable strainer is appreciated for filtering out particles from old gas cans. Its 1-liter capacity is generous for topping off or transferring fuel from a container.
However, the rigid plastic construction is less forgiving than rubber or silicone models. Several users reported cracking after dropping it on concrete. If you need a durable funnel for frequent use, consider a more robust material. The wide mouth also may not fit some modern capless fuel systems without an adapter.
- Large 1-liter capacity for multiple uses
- Removable strainer filters debris
- Affordable price point
Pros: Very low cost; Includes strainer for added protection
Cons: Plastic may crack if dropped; Not as flexible for tight spaces
4. OEMTOOLS 24426 Flex-Funnel: Best Flexible Design
The OEMTOOLS 24426 Flex-Funnel uses a high-temperature silicone that can handle hot fuel or engine bay use. In our evaluation, its collapsible design is a major advantage for storage, folding flat to fit in a tool bag. The non-slip ring helps keep it in place on the filler neck.
One downside is that the silicone material can be too flexible when supporting a full fuel can, causing it to bend and potentially spill if not held steady. Some owners also noted that the funnel does not have a built-in vent, so pouring can be slow. It is best for careful, one-handed use.
- Silicone construction withstands high heat
- Collapsible for compact storage
- Non-slip grip ring
Pros: Heat resistant for hot engines; Very flexible and easy to store
Cons: Silicone can be floppy when full
5. TeraGear Fuel Funnel with Flexible Spout: Best for Capless Fuel Systems
For modern vehicles with capless fuel systems, the TeraGear funnel is a smart choice. Its flexible spout is gentle on the flapper door, reducing the risk of damage. We compared its design with standard funnels and found the included storage bag keeps it clean in the trunk. Owner feedback highlights its convenience for emergency fuel transfers.
However, some users reported that the spout does not create a perfect seal on every filler neck, leading to minor splashes. The plastic body feels less durable than rubber alternatives. If you have an older vehicle with a traditional cap, this funnel may not be necessary.
- Designed for capless fuel filler necks
- Flexible spout prevents damage to flapper door
- Comes with a drawstring storage bag
Pros: Safe for capless systems; Portable storage bag
Cons: Spout may not seal tightly on all necks
6. Lisle 32800 Gas Can Funnel: Best for Gas Cans
The Lisle 32800 is a straightforward funnel tailored for use with gas can spouts. Its vent tube is effective at preventing the glugging that often occurs when pouring from a can. We evaluated owner reviews and found it reliable for transferring fuel from a can to a vehicle or equipment.
However, this funnel is not designed for direct pump nozzle use, as the opening is too small. Some users noted that the plastic is thin and may crack under pressure. It is best suited for occasional use with gas cans rather than frequent fueling.
- Fits standard gas can spouts
- Vent tube reduces glugging
- Simple, no-frills design
Pros: Works well with gas cans; Low price
Cons: Not universal for all filler necks; Plastic feels thin
7. Valleycom 2-Pack Funnel Set: Best Value Set
The Valleycom 2-Pack offers two funnels at a budget-friendly price, making it a practical choice for basic needs. The large funnel includes a strainer, which is useful for filtering fuel. We found that owner feedback appreciates the value but notes the plastic is thin and prone to cracking.
Neither funnel has a vent, so pouring can be slow and messy. They are best for occasional, non-critical use. If you need a durable, long-term solution, spend more on a single high-quality funnel.
- Includes two sizes for different tasks
- Strainer in large funnel
- Very affordable
Pros: Great value for the price; Versatile sizes
Cons: Low durability plastic; No venting feature
Frequently Asked Questions
What size funnel do I need for a car gas tank?
Most car filler necks are about 1.5 to 2 inches in diameter. A funnel with a 2-inch or larger opening works well. For capless systems, use a funnel with a flexible spout to avoid damaging the flapper door.
Can I use a kitchen funnel for gasoline?
Kitchen funnels are not recommended because they are often made of materials that can degrade with fuel exposure or cause static discharge. Use only funnels designed for fuel, typically made of conductive plastic or rubber.
How do I clean a gas funnel?
Rinse with a small amount of gasoline or use a degreaser, then let it air dry completely. Avoid water as it can cause rust if the funnel has metal parts. Store in a sealed bag to keep dust out.
Do I need a funnel for a capless fuel system?
Yes, using a funnel designed for capless systems helps prevent damage to the flapper door. Many vehicles come with a special funnel in the trunk for emergency use, but a dedicated funnel is more convenient.
Are silicone funnels safe for gasoline?
High-quality silicone funnels rated for fuel use are safe and heat-resistant. However, check that the silicone is fuel-resistant and not just kitchen-grade, as some silicones can swell or degrade.
Our Verdict
After researching specifications and owner feedback, the No-Spill 1415 Multi-Use Funnel is our top pick for its flexible rubber design, built-in vent, and excellent spill prevention. For diesel owners or those needing a larger opening, the Hopkins 10305 GoFlo is a strong runner-up with its wide mouth and long hose.
