WE DON'T JUST SELL AMSOIL.

WE RUN IT.

Discover Our Story

It started with a disaster.

We took Becky's Jeep Gladiator in for a routine oil change. The shop drained the oil, forgot to refill it, and sent her home. The engine seized a mile down the road.

That was the last time we trusted someone else with our oil.

Ever since, we've changed our own oil — AMSOIL Signature Series, every time — on every vehicle we own. When you've watched an engine die because of something that simple, you stop cutting corners on what goes in it.

Josh spent years in enterprise technology and ran his own landscaping company, where he saw firsthand what the right lubricants do for diesel and small engine equipment under real working conditions. That experience, combined with what happened to Becky's Gladiator, made the decision easy. We became authorized AMSOIL dealers because we already believed in the product.

Mill City Synthetics is Josh and Becky Friesen — based in Woodbury, MN. We ride, we wheel, we wrench. The Snazzberry JL has seen Moab. The KTM has seen Nemadji. We don't recommend anything we haven't run ourselves.

If you've got a Jeep, a truck, a bike, or a piece of equipment you care about — we're the people to call.
