Quick Answers
Straight answers to what people ask us most.
Do I need an appointment?
Appointments are the best way to make sure we have time set aside for your vehicle. Call (707) 725-0615 or use the request form and we will get back to you.
How long does an oil change take?
A standard oil and filter change is usually quick, but it depends on your vehicle. Call us and we can give you a realistic estimate.
What are the warning signs of bad brakes?
Squealing or grinding when you stop, a soft or sinking pedal, the car pulling to one side, or a brake warning light. If you notice any of these, get them checked soon.
How often should I get routine maintenance?
Most vehicles benefit from an oil change every few thousand miles and a bigger check-up at regular mileage steps. Your owner manual lists the schedule, and we can help you follow it.
My check engine light is on. Is it safe to drive?
A steady light usually means get it checked soon. A flashing light means stop driving as soon as it is safe and call us. Our diagnostics find the exact cause.
What hours are you open?
Monday to Friday, 8 AM to 5 PM. We are closed Saturday and Sunday. Find us at 1500 Ronald Ave, Fortuna, CA 95540.
