STAR Smog Check in Oceanside, CA
Oceanside STAR Smog Check is a test-only, STAR-certified smog station at 3940 Mission Ave, open seven days a week. We inspect cars, trucks, vans and hybrids for Oceanside drivers and Camp Pendleton families, including vehicles whose DMV notice requires a STAR station. Walk in, book online, or call (760) 439-8000.

Plenty of the cars we inspect arrived with a family on orders to Camp Pendleton, and weekend hours mean the check doesn't have to compete with duty hours. Test-only means the inspection is the whole job: we run it, then explain the results plainly.

What to bring
You need your vehicle and your DMV renewal notice. The notice states whether the vehicle needs a smog certification and whether that certification must come from a STAR station. Registering a car here for the first time, or selling one? Bring whatever paperwork DMV mailed you. If you've misplaced the notice, call us and we'll tell you what works.
How the inspection works
Arrive or book ahead
Walk-ins welcome any day we're open. Booking online saves your spot.
The test
We record the vehicle in the state's smog system and perform the inspection required for its model year. For most modern cars, trucks, and vans, that means connecting to the onboard computer and inspecting the emissions equipment.
The report
You get a vehicle inspection report showing the result and any open safety recalls, and we walk you through it. A smog certificate is good for 90 days.

If the vehicle doesn't pass
No station can tell you a car will pass before it's inspected. If yours doesn't:
- We explain the report. You'll know which items didn't pass and why they matter.
- You choose the repair station. A licensed test-and-repair or repair-only station of your choice does the emissions work; BAR's Auto Shop Locator lists them.
- We retest it here. Within 30 days of the paid, failed inspection, the $30 smog retest applies (retest terms).
If the fix involved disconnecting the battery or erasing codes, drive normally for a week or two before the retest so the readiness monitors can reset.

Frequently asked questions
What is a STAR-certified station?
STAR is a program of California's Bureau of Automotive Repair. To be part of it, a station must meet performance standards the BAR sets and keeps reviewing. If your DMV notice says the smog certification must come from a STAR station, we can do it. We inspect vehicles without that requirement as well.
What do I need to bring?
Your vehicle and DMV renewal notice. For a first California registration or a sale, bring the documents DMV sent you too.
How often does California require a smog check?
For most vehicles, once every two years with registration renewal. Gasoline vehicles in their first eight model years are generally exempt from that check and pay a smog abatement fee. A smog certification is also commonly needed when a vehicle changes ownership or is registered in California for the first time. Your DMV notice spells out what applies.
What happens if my car fails?
We explain the report, a licensed repair station you pick does the work, and the $30 smog retest here applies within 30 days.
Do you test hybrids and diesel trucks?
Hybrids, yes: they follow the same smog schedule as gas cars. Diesel rules depend on model year and weight rating, so call (760) 439-8000 to confirm we can test your diesel before you come.
I just moved here on military orders. Does my car need a smog check?
Most likely. A smog check is required for a car's first California registration, and military members are not exempt; fully electric vehicles are. For registration questions tied to your orders, ask DMV.
