Environmentally Responsible Auto Care & Recycling
Committed to Recycling Waste Oil, Fluids & Automotive Materials to Reduce Environmental Impact
We take pride in operating as an environmentally responsible automotive facility by properly recycling waste oil, antifreeze, transmission fluid, power steering fluid, gear oil, and other automotive materials whenever possible. Our commitment to sustainability helps reduce environmental waste while promoting cleaner and safer practices within the automotive industry.
In addition to recycling, we also maximize resource efficiency by utilizing recycled oil-based fluids to help heat our buildings during colder months.

Frequently Asked Questions
Planning your visit
Where do I leave my keys after hours?
Look for the brass mailbox at the first bay door. Take a night-drop envelope and write down your name, phone number and what you’d like us to check. Seal the key inside and slide the envelope through the slot in that door.
Will I see an estimate before repairs start?
Yes. After the inspection, we send you a digital report by text and email. You can see the technician’s notes, photos or video before we call to go over the estimate. We price each concern separately and give you a total with parts, labor, fees and taxes. We ask for your approval before starting repairs or doing additional work.
Can I bring my own parts?
No. We supply the parts we install. We normally choose parts from an original equipment manufacturer, though we may recommend another supplier if they make a better part for the repair.
How much does it cost to diagnose a problem?
Diagnostic work starts at $212. Allow at least an hour for a typical appointment. A problem that comes and goes can take longer to find. If we need more time, we explain the added cost before proceeding.
