What Does McLearen Shell Do During a Smog Check?
We inspect your car or truck's emissions-control equipment to measure the number of pollutants your vehicle is emitting.
First, McLearen Shell will analyze your car or truck's OBD computer system, emissions-control system, and check engine light codes for standard warnings that your emissions system is no longer functioning properly.
Next, we will inspect your car or truck's gas cap, ignition timing, exhaust gas recirculation system, fuel, and evaporative system.
Finally, we will perform a Tailpipe Emissions Inspection which measures the type and quantity of any pollutant emitted from your vehicle's tailpipe.

Took our Acura RDX in for brake service today. The staff at McLearen Shell did an excellent job, replacing the front discs & rotors. They advised that the rear pads still had 50% material remaining. Have had a variety of automobiles serviced at this service station over the last 25 years and there service remains outstanding and very reasonably priced. Highly recommended.

Great team at McLearen Shell, have regularly changed out brakes, bulbs, oil, valve cover gasket, spark plugs, etc. on a 1998 Gen 4 Camry LE for the past three years. Trustworthy, professional and they know these older still-running vehicles. Always respectful to Ladies interested in vehicle mechanical function and maintenance as well
Great job - I had an older vehicle and they were able to make repairs to keep it safe, and able to pass inspection - all at a very fair price. I highly recommend the McLearnen on Centreville Road to anyone needing correctly done car repairs at a fair price - thanks so much - Doug Kister
