Mazda owners tend to take their vehicles seriously. They bought a car that's engineered differently, and they want a shop that treats it the same way. CX-5 owners show up in our reviews more than once, which in the Fox Valley means something.
Here's something most Mazda owners don't know about us. The name Stoiched comes from stoichiometry, the chemistry of perfect combustion, the ideal ratio of fuel to air in an engine. Mazda's SKYACTIV technology is built on exactly the same principle, engineered to hit the stoichiometric air to fuel ratio more precisely than conventional engines. Stoiched and Mazda share a philosophy before the first bolt turns.
That alignment goes beyond branding. When a CX-5 or Mazda3 comes into the shop, it gets a thorough digital inspection, photos of every finding sent to your phone before any work begins. You approve what gets done. Every repair is backed by our 2 year, 24,000 mile warranty plus NAPA's nationwide coverage as a NAPA Auto Care Center.
From CX-5 SKYACTIV engine service to Mazda3 brake jobs, every Mazda repair gets the precision the brand was built on, diagnosed right, fixed right, backed by a real warranty.
The CX-5 is the most common Mazda at Stoiched and a Fox Valley favorite. Oil changes with Mazda spec 0W-20, SKYACTIV engine diagnostics, brake service, AWD inspections, and timing chain checks that keep this engine running as Mazda intended.

A bigger Mazda repair doesn't have to wait. We offer Synchrony financing so your CX-5, CX-50, or Mazda3 gets the work it needs now, not when the timing is convenient.
Mazda engineers spent years developing SKYACTIV technology around one core goal, achieving the ideal stoichiometric combustion ratio, around 14.7 parts air to 1 part fuel, the point where an engine runs cleanest and gets the most power per drop of fuel. That same idea is where the Stoiched name comes from, which is why a precision brand like Mazda and a precision shop are a natural fit. Below is some of what we watch for on Fox Valley Mazdas.
The CX-5 is the most common Mazda in our bay and a proven Fox Valley favorite. Its SKYACTIV-G engine isn't just a marketing name, it's a specific compression ratio, a specific fuel delivery system, and a specific maintenance schedule. We service it accordingly, with Mazda spec 0W-20 oil, engine diagnostics, AWD inspections, and timing chain checks that keep it running exactly as Mazda intended.
The Mazda3 is a driver's car, responsive and precise, and it rewards proper maintenance. The same goes for the Mazda6. We handle engine service, transmission maintenance, suspension work, and brake inspections for both, keeping the responsive feel these cars are known for rather than letting worn components dull it over time.
SKYACTIV engines require 0W-20 full synthetic oil and specific service intervals. Using the wrong viscosity or a lower grade oil works against the precise tolerances these engines are built around. We use the correct spec every time and follow Mazda's maintenance schedule, flagging items coming due so nothing sneaks up on you.
Mazda's KODO tuned suspension is a big part of why the CX-5 and Mazda3 feel the way they do. Worn struts or an alignment that's drifted out of spec erodes that feel quickly, and Wisconsin roads are hard on suspension components. We inspect the full system and keep alignment within Mazda's precise spec to protect both handling and tire life.
The CX-9 and new CX-90 are growing in popularity across the Fox Valley, and the turbocharged SKYACTIV-G 2.5T engine in these larger SUVs has its own maintenance needs. Turbo engines run hot and ask more of their oil, so staying on schedule matters even more. We handle the full maintenance schedule for these models, including timing chain checks on the 2.5T.

Yes. SKYACTIV engines call for 0W-20 full synthetic oil, and we use that exact spec every time, not a generic substitute. The right viscosity matters on these engines because they're built around precise tolerances, so we follow Mazda's specification rather than cutting corners.
No. Under the Magnuson Moss Warranty Act, Mazda cannot void your factory warranty because you chose an independent shop, as long as the maintenance follows manufacturer specifications using quality parts. Our ASE certified technicians follow Mazda's service specs and document all work.
Yes. We handle the full maintenance schedule for the CX-9 and CX-90, including the turbocharged SKYACTIV-G 2.5T engine. Turbo engines run hot and ask more of their oil, so we stay on top of intervals and check the timing chain as part of regular service.
