In order to help our racers we will be modifying our spec oil rules to match the current spec just issued by SKUSA. Please note this ONLY applies to those racers running an X30 engine.

IAME OIL ANNOUNCEMENT

Monday, 18 February 2019 16:04
At the request of national competitors and engine builders, effective immediately, SuperKarts! USA will allow a slight modification to the spec oil rule for all IAME X30 and SSE powered classes in SKUSA competition.

The move comes in response to concerns about elongating the life and durability of lower rod bearings, and we strive to pursue initiatives that benefit teams, engine builders, and our racers.

Beginning at the SKUSA Winter Nationals, SKUSA will begin allowing the optional use of 50% castor oil to the spec fuel mixture. To be clear, this means 4oz of castor oil + 4oz of Motul 2t + 1 gallon of VP12 gasoline.

Normal fuel tests will still be conducted, and governed accordingly. The following is a list of some known Castor Oils that can be utilized:

  • Burris Castor Oil (902-1)
  • Maxima 927 Castor
  • Klotz BeNol – BC175
  • Blendzall BC460 Pure Castor
  • Nature’s Oil Castor Oil
