The Route 66 Sprint Series, presented by Franklin Motorsports and MG tires has announced that Elf HTX909 has been selected as the Official Oil for competition in 2021. This will apply to all classes in USPKS sanctioned events, and all 2 cycle classes in Route 66 Sprint Series sanctioned events.

IAME representatives have indicated that this is their preferred choice of oils for engine longevity. Elf is a product of Total, and the HTX909 has been used successfully by other karting series utilizing the same IAME engines that USPKS does. In testing and real world application, the Elf product has provided superior engine wear characteristics, and has proven very usable in varying weather conditions.
