San Juan Auto Smog in Fair Oaks: Hours & Services

San Juan Auto Smog in Fair Oaks is a STAR-certified smog check and full-synthetic oil change shop at 4701 San Juan Ave, Fair Oaks, CA 95628, serving drivers across Fair Oaks, Carmichael, Sacramento, Citrus Heights, Orangevale, and Gold River.

If you landed here because your DMV renewal notice is due, or because you need a STAR station for a directed test, this page walks through what the shop tests, who needs an appointment, and what the oil change packages include.

Everything below comes from the shop's own service list, so you can match your vehicle to the right visit before you call or book.

What does San Juan Auto Smog actually test or service?

The shop runs STAR-certified smog checks for current-model vehicles and older cars, plus smog testing for RVs, vans, heavy trucks, and many diesel vehicles, along with full-synthetic oil changes. That's the full service list: a standard smog check, a smog check for 1999-and-older vehicles, smog testing for larger and diesel vehicles, an oil change on its own, and a combined smog-and-oil visit.

Does it handle older vehicles?

Yes. The older vehicle smog check covers 1999-and-older cars, which often take longer to test than newer OBD-equipped vehicles, so an appointment is recommended rather than a walk-in.

Can RVs and diesel vehicles get tested here?

Yes. RV, van, and heavy truck smog testing is available, and many diesel vehicles can be tested too. Because these vehicles take more time on the rack, booking ahead is recommended instead of walking in.

Do you need an appointment, or can you walk in?

Walk-ins are welcome for 2000-and-newer vehicles; everything else works better scheduled. That includes 1999-and-older cars, RVs, vans, heavy trucks, and every oil change booking.

Why do older and larger vehicles need a booking?

Older vehicles and diesel, RV, and heavy-truck testing take longer and sometimes need different equipment setups than a standard newer-car smog check. Scheduling ahead means the right bay and equipment are ready when the vehicle arrives, instead of waiting behind walk-in traffic.

What if you just need a quick renewal smog?

If your DMV notice is for a 2000-or-newer vehicle and you don't need a directed STAR test, walking in is the fastest route. Bring your registration renewal notice so the test can be logged against the right record.

What does it cost to get smogged or get an oil change here?

Smog pricing depends on vehicle type, so an exact quote takes a quick call, but oil change pricing is set in three packages, and combining the two services knocks $45 off the total. Transparent pricing means no surprise line items once the car's on the rack.

1. Good Package, $110.99. Full-synthetic oil change with up to five quarts of oil and a standard filter.
2. Premium Package, starting at $174.99. Full-synthetic oil change, tire rotation, and a brake inspection.
3. Best Package, $204.99. Full-synthetic oil change, multi-point inspection, fluid check, brake check, and tire rotation.
4. Smog + Oil Combo, $45 off. Smog check and full-synthetic oil change in one visit, priced lower than booking the two separately.

Full details on each oil change tier are on the oil change page, and the STAR-certified smog check page covers what the test itself includes.
