Mercury Quickleen(51)

How often you use a fuel system cleaner depends on your engine, how you use it, and what the label recommends. Many people add it during regular fill-ups for ongoing cleaning, while others use it periodically as a maintenance cycle. If you’re returning to service after storage or you notice hesitation or rough idle, a treatment cycle may help, but results can vary.

• Follow the product’s directions for mix ratio and frequency.
• Check your owner’s manual for any restrictions specific to your engine.
• For everyday protection between deep cleanings, consider a fuel treatment as directed.
• Before seasonal storage, a stabilizer can help maintain fuel quality.

When shopping online, review the product page for usage details and safety information.

Using more additive than directed isn’t recommended. Overdosing can change the fuel’s characteristics and may lead to rough running, reduced lubricity in the fuel system, or sensitivity in components like pumps, injectors, and emissions equipment. Engines differ, so it’s best to stay within the labeled ratio.

• Measure carefully and do not exceed the product’s recommended amount.
• If you added too much, dilute by topping off with fresh fuel.
• Avoid stacking multiple additives unless the labels indicate they’re compatible.
• If performance issues persist, consider having a qualified technician evaluate the system.

Always follow the directions on the bottle and your owner’s manual for best results and safety.

The correct amount is listed on the product label, and that guidance should be your primary reference. Because mix ratios vary by product and engine type, avoid guessing.

1. Find the recommended dose on the bottle (often shown as an amount per gallon).
2. Confirm your tank’s capacity and estimate how much fuel you’ll add.
3. Use the bottle’s measuring marks or a clean, graduated container to measure.
4. Add the cleaner before fueling so it mixes thoroughly.

Do not exceed the maximum recommended concentration. If you’re unsure, review the product page or contact the manufacturer for clarification. Your owner’s manual can also provide guidance on additive use for your specific engine.

Many fuel additives are formulated to work with common ethanol blends, but you should always verify compatibility on the label. Additives don’t change the ethanol percentage in your fuel, so continue to follow your engine’s approved fuel requirements.

• Check your owner’s manual for the maximum ethanol content your engine allows.
• Confirm on the bottle that the additive is suitable for ethanol-blended gasoline.
• If your engine isn’t approved for higher-ethanol blends, an additive won’t make those blends acceptable.
• For seasonal storage, consider pairing with a stabilizer labeled for ethanol-blended fuels.

Review the product page for usage details and safety information, and follow the directions on the label for best results.

These products support fuel systems in different ways, and you can choose based on your situation:

• Engine & fuel system cleaner: Focuses on cleaning deposits in injectors, carburetor passages, and the combustion area. It’s typically used on a scheduled basis or when symptoms arise.
• Fuel treatment/conditioner: Helps keep fuel systems clean during everyday use and may include detergents and corrosion inhibitors for ongoing protection.
• Fuel stabilizer: Helps maintain fuel quality during storage by slowing oxidation and phase separation.

Some products can be used together, but always verify compatibility and never exceed labeled dosages. Check the product page for directions and your owner’s manual for engine-specific guidance.
