Our Story
Appleton's auto repair shop since 2016
Ryan Cerny started Stoiched Automotive in Appleton in 2016 with one simple idea, that auto repair shouldn't feel like a scam. Drivers deserved to know exactly what was wrong, what it would cost, and what they were getting.
The name comes from stoichiometry, the science of getting the fuel to air mix exactly right for clean combustion. That's how we approach every repair. Not close enough, not good enough, right.
Since opening on Cold Spring Rd, we've grown into one of the Fox Valley's most trusted shops, serving drivers from Appleton, Neenah, Menasha, Greenville, Kaukauna, Oshkosh, Hortonville, and Little Chute. A 4.9 star rating across 400+ real local reviews says it better than we could.

In-Depth Guide
Auto repair in Appleton WI, what you should know
If you've ever searched "auto repair near me" and got a list of shops you've never heard of, you're not alone. Finding a mechanic you can actually trust in Appleton takes more than picking the closest one. Here's what really matters.
Oil change and maintenance
Most folks drive through Appleton every day and don't think twice about their oil, until the light comes on, and by then there can already be engine wear. We recommend keeping up with the oil change interval in your owner's manual, and every oil change here includes a visual check of your fluids, belts, and filters with a report sent to your phone. It's the kind of thing that catches a small problem before it turns into a big one. We're on Cold Spring Rd, easy to reach whether you're coming from the east side near Richmond Street or in from the west off I-41.
Brake repair
Appleton winters are no joke. Snow, ice, and freezing temps put real stress on your braking system. If you hear squealing when you stop or the pedal feels soft, don't wait. Pads that wear down completely can score your rotors and turn a small job into a much larger one. We see this a lot in spring after people put off brake work all winter. Our brake service covers pads, rotors, calipers, and fluid, and we send a digital report with photos showing the wear so you can see it yourself.
Engine and transmission repair
Engine and transmission jobs are the big ones, the kind where people get nervous and start calling around. Here's the thing, cheap transmission work done wrong ends up costing far more. Our ASE certified techs handle everything from timing belt replacements to full rebuilds, and every major repair is backed by our 2 year, 24,000 mile warranty, longer than most shops in the Fox Valley offer.
The stoichiometry connection
Our name isn't random. Stoichiometry is the chemistry behind getting the exact right ratio of air to fuel for clean combustion. That obsession with getting it exactly right is built into the name, and every repair reflects the same standard. Not almost right, exactly right.
Serving the whole Fox Valley
Our shop is at 2600 Cold Spring Rd, but we serve drivers from across the region. Folks from Neenah and Menasha drive up US-10 or WI-441, Greenville is about five minutes west on Hwy 76, Kaukauna hops on US-55, and plenty of Oshkosh drivers come up US-41 because the reputation travels further than the zip code. Wherever you're coming from, we'll get your car looked at quickly.
