Fuel Testing at Pro Tour Springnats
Written by John Motley - National Tech Director   
Wednesday, 12 June 2019 11:03
As many of our competitors know, we took several fuel samples at the SKUSA Pro Tour SpringNationals event in Utah last month for further testing.

The following entrants’ fuels were tested:
  • Freddie Slater #727 X30 Junior
  • Ryan Norberg #N1 X30 Senior
  • Matt Johnson #517 X30 Master
In addition to SKUSA’s own analysis, we are happy to report that the three samples submitted to the VP Fuel’s head chemist were all determined not to have any additional ingredients beyond VP C12 and the allowed lubricants.
