How often should I get an oil change?
Every 3,000-5,000 miles for conventional oil; every 7,500-10,000 miles for full synthetic — follow your owner's manual.
Synthetic oil extends intervals significantly
Severe duty driving (towing, stop-and-go) shortens intervals
Modern vehicles often have oil-life monitors — follow them
Skipping intervals causes sludge buildup and accelerated wear
Per manufacturer recommendations and ASE technician guidance.
What does a cabin air filter do and when should I replace it?
The cabin filter cleans air entering your car's interior — replace it every 15,000-25,000 miles or sooner if you notice weak airflow or musty odors from the vents.
Clogged cabin filter cuts A/C and heater airflow significantly
Dirty filter allows allergens, dust, and pollutants into the cabin
California wildfire smoke seasons demand more frequent changes
Located behind the glove box on most vehicles — quick replacement
A fresh cabin filter also reduces odors and improves defroster performance
Per HVAC filter standards and manufacturer service intervals.
