More Than a Dealership
At Mill City Synthetics, our journey is rooted in passion and a commitment to doing things right. We’re Jeep and powersports people who run AMSOIL in everything we own — the Snazzberry JL, the KTM 450 EXC-F, the CFMoto Ibex 450, and everything else in the garage. We became AMSOIL dealers because we already believed in the product, and today we’re the go-to source for AMSOIL synthetic lubricants across the Twin Cities metro and beyond.
