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.
