Smog Repair & Lube
Smog checks, retests, oil changes and brake work on Parkside Drive in Walnut Creek, six days a week.
About
Smog Repair & Lube works from 1225 Parkside Drive in Walnut Creek, in central Contra Costa County, and answers 925-927-5000. The shop keeps two websites tied to that address and number: one under the Smog Repair & Lube name, centred on oil changes and repairs, and one under the Star Smog name, centred on emissions testing. Drivers who know it as Star Smog or Star Smog & Lube have found the same business. The imported records listed it as ISMOG Repair & Lube, with Daniel Martinez as owner.
Services on the shop's own sites
Smog checks are the core of the work. The shop says it is a STAR test-and-repair station. That matters for two reasons: some DMV renewal notices require a STAR station, and a test-and-repair station can fix a car that fails and then retest it without sending you elsewhere. The Bureau of Automotive Repair publishes the status of every smog station, so check this one at bar.ca.gov before you go.
The lube side covers oil changes with conventional or synthetic oil, tire rotation, air filter replacement and a five-point safety check done alongside each oil change. General repair is listed too, with brake and lamp work called out by name, and the shop says it works on all vehicle types.
Before you drive over
Hours are 8:30 a.m. to 5:00 p.m., Monday through Saturday; the shop is closed Sunday. Appointments can be made through its online scheduler, which usually beats waiting for an open bay. Bring the DMV renewal notice, since it states whether a STAR station is required, along with your registration. A lit check engine light means an automatic smog failure in California, so have the cause diagnosed first. For any repair, state rules entitle you to a written estimate before work begins and a call before extra charges are added; ask for both, and ask for the old parts back if you want them.

Common questions
Typical for this type of businessWhat is a STAR smog station?
STAR stations meet extra performance standards set by the Bureau of Automotive Repair. Some DMV renewal notices say the inspection must be done at a STAR station; the notice states whether yours does.
What happens if my car fails a smog check?
The car must be repaired and retested before registration can be renewed. A test-and-repair station can do both. Income-eligible drivers can ask the state Consumer Assistance Program about repair help.
Can I pass a smog check with the check engine light on?
No. In California an illuminated check engine light causes an automatic failure. Have the fault diagnosed and repaired, then drive normally for a while before the test so the car's monitors are ready.
How long does a smog check usually take?
The inspection itself is usually finished in under an hour at most stations. Booking an appointment ahead and bringing the DMV notice and registration helps avoid a wait.
