All but 1 model of 2010 phazers use regular fuel

Glad to see Venture Lite~Mtx~Gt have switched to Regular next year. But for some reason the Rtx is still Premium?

They've always been able to run both. The premium will supply about 2 more HP if I remember the details from the Demo ride when they came out. Computer compensates automatically.

I usually run premium but on the last ride had to run regular because no one in Paradise had premium. I didn't notice any effects.

My knock sensor will illuminate.

For every 5 gallons of 87 octane I add 3 liters of Track Tek 118 octane---> 93 octane :~)
