Hi there -
New to the ROK, and want to ensure that I am running the right fuel so I don’t damage the motor.
At my track (in Canada), they run Sunoco Race Fuel - Standard 100 octaine leaded fuel. I guess this keeps things consistent amongst the racers. In the US, I beleive the ROK class uses Sunoco Race Fuel - Supreme - which I beleive is 112 octaine leaded fuel. Not sure if there are any other differences.
If I am just doing some training / lapping sessions, do I need to run the race fuel, or can I use pump gas? In Canada I can get Ultra94 - which is 94 octaine unleaded pump fuel. If I mix this to the correct ratio, will this hurt the motor? The track indicated it would cause detonation and damage the motor.
I have read to stay away from any fuel containing ethanol to avoid drying out the seals and to do away with the water/moisture content.
Does anyone have any opinion about pump vs race fuel for fun lapping sessions? The last thing I want to do it damage the motor during practice sessions.
Thanks for your opinions.
