The Development of an Optimized Slow Release Lubricity Enhancing Fuel Filter

With the pending introduction of ultra low sulfur diesel fuel, lubricity is becoming a more pressing concern. It has long been recognized that certain additives can dramatically improve fuel lubricity. However when manual addition of liquid additives is used to treat fuels human error can be introduced resulting in incorrect additive concentration or use of an inappropriate additive. To overcome the issues with manual additive addition and provide additional protection for customers using poor lubricity fuels a slow release lubricity enhancing fuel filter was introduced in 2002. This filter was effective but had some limitations. To address these limitations and to further optimize this technology a novel release mechanism was developed and introduced in 2006. This paper will document the development and validation of this technology.
