Air filter oil is the cheapest engine insurance you can buy. A correctly oiled foam filter traps particles down to around 5 microns while still flowing the air your engine needs, so dust never reaches the bore. Match the product to your filter type and riding conditions.
| Product type | Best for | Format | Typical sizes |
|---|---|---|---|
| Liquid filter oil | Deep, even saturation of foam filters | Pour and knead | 500ML to 1L |
| Spray filter oil | Fast re-oiling, less mess | Aerosol up to 750ML | 600ml to 750ML |
| Bio filter oil | Riders wanting a biodegradable option | Pour or spray | 1L |
| Foam filter cleaner | Stripping old oil before re-oiling | Spray or soak | 600ml to 600g |
Always clean before you re-oil. Foam filter cleaner breaks down old oil and embedded grit so the new coat bonds evenly across 100% of the foam surface. Let the filter dry fully, then apply oil until it is uniformly coloured with no dry patches. Liquid oils give the most thorough 360 degree coverage on dual-stage foam; sprays suit a quick trackside refresh in under 5 minutes.
Choose bio formulas if you wash filters near waterways or want lower environmental load. Service intervals tighten in dust: re-oil every 1 to 2 rides in sand or desert, every 3 to 5 rides on hardpack, and at each major service for road bikes. Keep one cleaner and one oil on the shelf so a dirty filter never stops a ride.
Frequently asked questions
What is the difference between liquid and spray air filter oil?
Liquid filter oil is poured onto the foam and kneaded in for the most thorough saturation, ideal for dual-stage filters and dusty conditions. Spray oil is an aerosol that re-coats a filter fast with less mess, suiting quick trackside refreshes. Both seal the foam against fine particles down to around 5 microns.
Do I need a separate cleaner before re-oiling my air filter?
Yes. Foam filter cleaner strips old oil and embedded grit so the new oil bonds evenly across 100% of the foam. Re-oiling over a dirty filter traps dust against the foam and reduces airflow. Clean, dry fully, then apply fresh oil until the foam is uniformly coloured.
What does bio air filter oil mean?
Bio air filter oil uses a biodegradable formula with lower environmental load, which suits riders washing filters near waterways. It still seals foam filters against dust as effectively as standard oil. Putoline and Ipone both offer bio options in this range alongside their standard liquid and spray oils.
