Abstract:

The general aviation gasoline user community has established a goal to reduce the amount of lead added to current aviation gasoline. This endeavor evaluated lead additive levels in commercially available aviation gasolines currently meeting the ASTM D 910 specification for 100 low lead. Certificates of Analysis were procured for contemporary loads of aviation fuels from a variety of fixed-base operators (FBO) and test laboratories, as well as fuels used by engine manufacturers for engine certification. Also, fuel samples were purchased from various FBOs and sent to laboratories for full specification properties analyses. A sample set of 83 individual data points were reviewed for the lead content (converted to grams of lead per liter of fuel), motor octane number (MON) per ASTM D 2700, and supercharge performance number per ASTM D 909. The samples were also segregated by regions using time zones of the manufacturer location, and by refinery (blinded for this report) in an attempt to identify, if any, relationships by region or by refiner. From this sample set, 43% of the fuels had lead contents that were more than 20% below the maximum allowable lead content. No strong correlation between lead level and MON was found. More than 95% of the fuels had MONs greater than 102 per ASTM D 2700.
