I get a little more than ten minutes in my ST-R with the 9.5mm insert. That is good fuel economy considering the output of the engine. I am planning to use the next smaller insert to see if the economy improves without dropping the power too much.
Overall I like the Spec 3. Less than half the price of a Nova and the same track performance.
