Professional filter protection that takes 15 minutes
The air filter is your engine's guardian, stopping tons of dust, mud and sand every day before they reach the cylinder. You don't need to be a mechanic to give it proper protection. OC1 Air Filter Oil makes filter oiling simple, quick and effective, while the distinctive green color instantly shows where the product has already been applied.
Off-road riding, motocross races or enduro training are extreme conditions for the intake system. Every sand particle that penetrates the filter acts like sandpaper in the cylinder, shortening engine life by up to half. Proper air filter oiling is an investment that pays back many times over through years of trouble-free riding.

Who should use this product?
OC1 Air Filter Oil was created for everyone who wants to extend engine life and avoid costly repairs. You don't need to be a professional mechanic to care for your air filter at the highest level. The product works equally well in the hands of motocross and enduro competitors who need certainty that the filter will withstand extreme race conditions and must be perfectly oiled before every competition or training, as well as off-road riding enthusiasts regularly facing dust, mud and difficult offroad conditions during weekend trips or longer enduro adventures.
OC1 Air Filter Oil is also essential support for quad owners — used for fieldwork or recreation — which often operate in very dusty conditions during agricultural or forestry work. Motorcycle workshops and service centers professionally maintaining off-road motorcycles consider having this product in their offer as a customer service standard.
When to use filter oil?
Regular air filter oiling is the key to long engine life. Knowing when to do it allows you to maximize the product's potential and protect the engine from damage.
- After every filter cleaning – after using Air Filter Cleaner and complete drying, always apply a fresh layer of oil; a clean but unoiled filter lets contaminants straight into the cylinder.
- Before races and training – check filter condition and re-oil if needed; a motocross race means extreme conditions where the filter must be perfectly prepared.
- After extreme riding conditions – after rides in particularly dusty conditions or through deep puddles and water crossings, extreme amounts of water or dust can reduce the protective coating's effectiveness.
- When filter color changes – when you notice the filter has changed from green to dirty, brown or black, it's a sign the cleaner has done its job and it's time for regeneration.
- Before the season – in case of long-term motorcycle storage, it's worth checking the filter before the season, cleaning it and oiling with fresh oil before the first ride.


Why does waterproof coating matter?
Water is one of the greatest enemies of the combustion engine, and off-road motorcycles are particularly often in contact with it. During water crossings, puddles or riding in rain, huge amounts of water can enter the intake system. Regular filter oil dissolves under moisture, losing its protective properties after the first contact with water.
OC1 Air Filter Oil creates a one hundred percent waterproof barrier that doesn't let a single drop through. Whether you cross a shallow stream or a deep ford, the filter remains effectively oiled. Water runs off the outer foam layer without penetrating deep into the filter structure. The engine has access to dry, clean air even in the toughest conditions.
How does the distinctive green color work?
The innovative green color is OC1's proprietary solution that completely changes the way filters are oiled. With traditional colorless oils, you have to guess whether you've covered the entire filter surface. It's easy to miss spots at inner edges or in hard-to-reach places. These unoiled areas are open gates for dust and sand straight into the cylinder.
Thanks to the intensely green color, you instantly see every centimeter of filter that has been covered with oil. Light filter foam combined with green oil provides clear contrast that eliminates all doubt. You can be certain that the entire filter, both outer and inner surface, is evenly protected.

1. Filter preparation
Remove the filter from the motorcycle and thoroughly clean it with OC1 Air Filter Cleaner. Wait until the filter is completely dry before applying oil. A wet filter won't accept the product properly and protection will be incomplete.
2. Shaking the can
Before use, shake the aerosol thoroughly for 10-15 seconds to activate the formula and mix the ingredients. This step ensures consistent product properties during application and optimal viscosity.
3. Oil application
Holding the aerosol approximately 15-20 cm from the filter, evenly spray the entire outer and inner surface of the filter. The green color will immediately show covered areas. Pay special attention to edges and hard-to-reach spots that are often missed.
4. Working in the oil
Gently squeeze and knead the filter so the oil spreads evenly throughout the foam structure. Not just on the surface, but deep into the material. This is a crucial step that ensures effective filtration across the entire working surface.
5. Drying time
Set the filter aside for approximately 15 minutes to allow excess oil to evaporate and the product to properly absorb into the foam. After this time, the filter is ready for installation. Don't shorten this time — it guarantees optimal protection effectiveness.
Important
Do not use the product on hot surfaces or near fire sources. Always work in a well-ventilated area. Avoid contact with eyes and skin, use protective gloves if needed. Store the aerosol at 5-25°C, away from direct sunlight. Do not puncture or burn the empty container.
Tip
To maximize filter and engine lifespan, create a maintenance routine. After every ride in dusty conditions, visually check the filter condition. If the green color has turned dirty brown or black, it's time for cleaning and re-oiling. Regularity is key to engine longevity. Motocross teams clean and oil filters after every practice and race — it's the best investment in machine reliability.
How often should I oil the air filter?
The air filter should be oiled after every cleaning with Air Filter Cleaner, before races, after rides in extremely dusty or wet conditions, and when you notice the green oil color has turned dirty. Under normal offroad conditions, this is typically every 3-5 rides, although motocross racers do it after every practice and race to ensure maximum protection.
Can I use this oil on other filter types?
OC1 Air Filter Oil is designed exclusively for foam air filters used in offroad motorcycles, quads and other offroad vehicles. Do not use it on paper filters, cotton K&N type filters or car filters. The formula is specially developed for foam structure and may not work properly on other materials.
Is the oil really 100% waterproof?
Yes, the OC1 Air Filter Oil formula creates a completely waterproof barrier that doesn't dissolve in water. You can safely cross streams, puddles or ride in rain without worrying about reduced filtration effectiveness. Water runs off the surface without penetrating deep into the oiled foam, protecting the engine from moisture in the intake system.
Why is the oil green?
The distinctive green color is a unique OC1 solution that allows visual control of entire filter coverage during application. Light foam combined with green oil creates a clear contrast, letting you immediately see areas already covered and spots still needing product application. This eliminates the risk of missing filter sections, which could lead to gaps and contaminants entering the engine.
How long must I wait before installing the filter after oil application?
After evenly applying the oil and working it into the foam, wait approximately 15 minutes for excess product to evaporate and oil to properly absorb into the filter structure. This time is needed for the filter to achieve optimal filtration effectiveness. Don't shorten this time, as it may reduce the coating's protective properties.
Do I need to use OC1 cleaner before oiling?
Although technically possible to use other foam filter cleaning products, we strongly recommend using OC1 Air Filter Cleaner. OC1 products are mutually compatible and created to work together. The cleaner effectively removes old oil and contaminants without damaging the foam or adhesive, preparing an ideal surface for fresh filter oil. This duo delivers best results and maximum filter lifespan.
How many times can I oil one filter?
A foam filter can be cleaned and oiled multiple times, typically throughout a season or longer, depending on usage intensity. The limitation isn't the filter oil but natural foam wear, which over time may lose elasticity or suffer mechanical damage. Regularly check filter condition for tears, deformations or loss of elasticity. When foam becomes hard or brittle, it's time to replace with a new filter.
Does the oil affect engine power?
OC1 Air Filter Oil has optimal viscosity that effectively traps contaminants while allowing air to flow freely through the filter. The engine gets adequate oxygen, doesn't lose power, and is simultaneously protected from dust, mud and sand. A properly oiled filter causes no power reduction, quite the opposite — a clean intake system is essential for optimal combustion and full engine performance.
Can I oil the filter more than once for better protection?
One evenly applied layer of filter oil is sufficient. Double oiling can oversaturate the foam, restricting airflow and potentially reducing engine power. The key is even coverage of the entire surface, both outer and inner, and working the oil deep into the foam structure. If you notice areas without green color, touch up those specific spots, but don't apply a second layer to the whole filter.
Is the product environmentally safe?
OC1 cares about the environment, designing formulas responsibly. Air Filter Oil contains no harmful chlorinated solvents, is safe to use and doesn't threaten ecosystems. Empty aerosols should be disposed of according to local regulations for aerosol product packaging waste.
Can I use this product on a quad or other offroad vehicle?
Absolutely yes. OC1 Air Filter Oil is designed for all vehicles equipped with foam air filters, regardless of type. Enduro motorcycles, motocross, quads, UTV vehicles or even some offroad buggies with foam filters will benefit from the same excellent protection. Versatility is one of the advantages of OC1 products.
