Fuel additive science is not definite. There are too many influencing factors and different requirements to produce the “ultimate additive” that universally works for all. What may work well on one engine does not guarantee success on another. This presents the need for different technologies to help match successful functions to the engine, fuel and requirements of the user.
This is also why it becomes difficult to recommend the best fuel conditioner for you and why Oilsyn and Archoil usually offer sample sizes of their most popular products to test and decide which works best for you and your vehicle.
Take Archoil AR6900-D or Oilsyn Diesel Power DNA as examples. They deliver a multitude of functions that include fuel stabilization, anti-foaming, cleaning (via detergents), lubricity (via a lubricant), cetane improver, and combustion improvement (via a combustion catalyst). These are all delivered chemically to the fuel, and obtaining a balance of functions becomes more of an art form than science because the functions can compete against one another.
Too much lubricity can reduce cleaning performance; too much detergent can reduce combustion catalyst performance; too much cetane improver can negate MPG gains being delivered by the combustion catalyst, and it goes on and on. When you consider that fuels vary in lubricity, cetane #, and detergent performance and combine this with the fact that engines respond differently to each of the functions mentioned above, it is no wonder it is impossible to achieve a 100% success rate with additive use. However, Archoil can get closer to it than most by offering a range of technologies that provide different functions or deliver similar functions differently. In contrast, most competitor products are simply cetane improver with a cheap mono-acid lubricant. This includes many of the popular brands.
This is where Oilsyn Diesel Race DNA enters the arena. It delivers even more cetane, the best performing lubricant on the market right now, and a combustion catalyst. It has low cleaning performance because that robs the engine of power. Diesel Race DNA cannot be beaten for the ultimate performance and lubricity. The difference is night and day when using this.
Oilsyn Hybrogen is helpful for maximum MPG and lowest emissions or with engines that don’t respond well to higher cetane diesel. Hybrogen is essentially an aggressive dispersant and combustion modifier. It helps clean by using cleaner combustion gases and reducing surface tension in the fuel system. There is no active detergent. This surface tension reduction also improves lubricity, yet there is no active lubricant. It improves combustion quality by manipulating the fuel rather than “treating” it.
We know from testing that some customers prefer Diesel Race DNA, some Diesel Power DNA, some Archoil AR6900-D and others Hybrogen. Most notice the greatest difference when using Diesel Power or Race DNA, simply due to the lubricant that is not found in any other diesel additive.
Quick summary of each product:
Oilsyn Diesel Race DNA – Designed for maximum performance and lubricity. Outstanding cetane improver, lubricant, and combustion improver. Much better on engines that respond well to additional cetane and where the customer is looking for a quieter engine.
Archoil AR6900-D MAX – Designed for all-around performance and protection. Good lubricant, stabilizer and cleaner, great cetane improver, and combustion improver. Often better on engines that respond well to additional cetane.
Oilsyn Diesel Power DNA – Designed for all-around performance and protection. Outstanding lubricant and cleaner, great cetane improver, and combustion improver. Often better on engines that respond well to additional cetane or where there is a requirement to reduce diesel clatter.
Oilsyn Hybrogen Road – Designed for maximum MPG and lowest emissions. Excellent dispersant and combustion modifier with gentle secondary cleaning and lubrication. Often works where MPG and power increase results have been less than expected with products that raise cetane.
Please note this is an approximate guide, and we are always available to advise further. However, we strongly recommend that customers test to see what works best.
