Looks like Tommys Karts is the place to buy oil, cheaper than the manufacturer. It may be about the same after shipping though. It said $8.00 minimum or something to that effect. I assume that is per gallon. They also had the heavy without caster oil (case) for $66.24, still a great price. I only use the caster free stuff, since in winter the caster oil gums up the engine. Does anyone know of a place that sells the oil in the center of the country for those of us out here?

Thanks
