Kerosene vs. diesel for cleaning O-rings
Kerosene, also known as #1 diesel fuel oil, and regular diesel, or #2 diesel fuel oil, are both suitable for cleaning o-ring chains. However, there are some key differences to consider when deciding between the two.
Kerosene is a lighter diesel oil than regular diesel, containing slightly less energy per gallon. This results in a drier burn with less lubricity, which can cause increased wear on fuel pumps and other parts such as rings, gaskets, and valves. An easy solution to this issue is to add automatic transmission fluid or 2-cycle oil to the kerosene. Kerosene is also particularly useful in changing the cold-weather handling temperatures of diesel fuel in winter.
On the other hand, diesel fuel is widely used for cleaning o-ring chains and is known to be effective. It is easily accessible and affordable, and it has the advantage of not being flammable, making it safer to work with. Diesel fuel is also a light oil that will not harm o-rings, and it can be used as a chain cleaner. However, it may leave a residue that can attract dirt over time and needs to be removed with another solvent.
Some people prefer to use alternatives like gasoline or petrol to clean their o-ring chains. These fuels can also effectively remove grime, but it is important to oil the chain afterward to prevent damage. Additionally, petrol tends to penetrate the o-rings and wash out the sealed-in grease.
Ultimately, the choice between kerosene and diesel for cleaning o-ring chains depends on various factors, including availability, cost, and personal preference. While both options are viable, it is important to consider the specific characteristics and potential drawbacks of each before making a decision.

Pros and cons of using diesel
Several online sources mention using diesel fuel to clean o-ring chains. However, some users have expressed concerns about the potential negative impact on the o-rings. Here is a list of pros and cons of using diesel fuel for this purpose:
Pros of Using Diesel:
- Effectiveness: Diesel is a fuel oil that can effectively clean grime and dirt from o-ring chains.
- Protection: Diesel leaves behind a residue that protects the metal of the chain.
- Cost-effectiveness: Diesel is generally cheaper than other cleaning options like kerosene.
- Accessibility: Diesel fuel is readily available at gas stations.
- Manual Recommendation: Some motorcycle manuals specifically recommend using diesel fuel for cleaning o-ring chains.
Cons of Using Diesel:
- Residue: Diesel evaporates slowly and leaves more residue compared to other solvents, requiring additional lubrication or protectant after cleaning.
- Hassle: Using diesel for cleaning may require removing the chain, which can be a time-consuming and dirty process, generating waste and requiring frequent replacement of parts.
- Safety Concerns: There are concerns about the potential impact of diesel on the o-rings, with some suggesting that it may damage or dry out the rubber over time.
- Alternative Options: Other cleaning methods, such as using soap and water or kerosene, are available and may be less cumbersome and provide similar results.

Alternatives to diesel
While diesel fuel is a popular choice for cleaning o-ring chains, there are several alternatives that can be used instead. Here are some options:
Kerosene
Kerosene is a refined form of diesel and has better lubricating properties. It is a common alternative to diesel for cleaning o-ring chains. Kerosene can be purchased at most gas stations and is often recommended for this purpose. However, it leaves the metal "naked", so you would need to apply a lubricant or protectant after cleaning.
WD-40
WD-40 is a water-repellent solution that can be used to clean o-ring chains. It is important to note that while WD-40 can help prevent rust, it is not a lubricant. After using WD-40, you may need to apply a heavier grease or wax to the chain.
Soap and Water
A simple mixture of soap and water can be used to clean an o-ring chain. After cleaning, it is important to let the chain dry completely before lubricating it.
Dupont Teflon Spray
Dupont Teflon spray can be used after cleaning your chain with water. It helps to protect the chain and keep it in good condition.
Chain Lube
A dedicated chain lube product can be used to clean and lubricate your o-ring chain. However, some people find that using lube attracts more dirt and grit to the chain.
Other Solvents
Other solvents, such as chain cleaner, can also be used to clean o-ring chains. These can be applied to a rag and used to wipe down the chain.
While diesel fuel is a common choice for cleaning o-ring chains, it is always a good idea to have alternatives. These options provide effective cleaning and lubrication for your o-ring chain, ensuring its longevity and smooth operation.

The importance of lubrication after cleaning
While diesel fuel can be used to clean an O-ring chain, it is important to note that lubrication is crucial after the cleaning process. Lubrication helps to reduce friction in the drivetrain, ensuring that the chain moves smoothly with minimal resistance. It also plays a vital role in protecting the metal surfaces of the chain from corrosion and rust.
Lubrication is essential after cleaning an O-ring chain because the cleaning process removes the existing grease and lubricant from the chain. This is especially important if you use kerosene to clean your chain, as it leaves the metal "naked" and more susceptible to corrosion. By applying lubrication, you are providing a protective layer that shields the metal from the elements and prevents rust formation.
Additionally, lubrication helps to ensure the long-term durability of the chain. A well-lubricated chain experiences reduced wear and tear, as the lubricant minimizes the accumulation of dirt and grime. This, in turn, leads to cost savings, as you won't have to replace the chain as frequently. Lubrication also helps to maintain optimal performance and efficiency, allowing your chain to run smoothly and quietly.
It is worth noting that not all lubricants are created equal. It is recommended to use a high-efficiency chain lube that is specifically designed for bicycle or motorcycle chains. These lubricants are superior to non-specific products as they are formulated to effectively repel dirt and water, keeping your chain clean and well-maintained.
When lubricating your chain, it is important to follow the manufacturer's recommendations for the type of chain you have. Open chains without seals require more frequent lubrication, while sealed chains, such as O-ring or X-ring chains, have built-in lubrication that only needs to be supplemented occasionally. Always inspect your chain regularly and listen for squeaks or grinding noises, as these can indicate a lack of lubrication.

The effectiveness of diesel in removing grime
Diesel fuel is effective in removing grime from o-ring chains. It is a fuel oil that works well as a cleaner, and many motorcycle manuals recommend its use. It is also inexpensive, at $4/gallon.
Diesel is often compared to kerosene, which is a refined version of diesel with better lubricating properties and a cleaner burn. Kerosene is considered cleaner because it leaves less residue, but this also means it leaves the metal "naked" and unprotected. Diesel, on the other hand, evaporates slower and leaves a residue that protects the metal.
Some people are concerned about the use of diesel fuel to clean o-ring chains, as they believe it might damage the o-rings. However, diesel fuel is light and will not harm the o-rings as long as they are not allowed to dry out after cleaning. It is important to oil the chain after cleaning with diesel fuel. Additionally, diesel fuel does not penetrate the o-rings and wash out the sealed-in grease, unlike petrol.
There are alternative methods to clean o-ring chains, such as using soap and water, or just water, followed by lubrication. However, some people find that dirt sticks to the chain even after using these methods. Other alternatives include using WD-40, kerosene, or a dedicated chain cleaner, but these options may be more expensive and less effective.
Overall, diesel fuel is an effective and inexpensive option for removing grime from o-ring chains. It is important to follow up with lubrication to protect the metal and prevent damage to the o-rings.
