What is a 30k 60k 90k mile service?

Manufacturer-defined major service milestones that replace fluids, filters, belts, and plugs on a schedule — the 30k/60k/90k framework is shorthand for escalating inspection depth.

  • 30k: air filter, cabin filter, fluid check, brake inspection, tire rotation
  • 60k: adds spark plugs (copper), transmission service, coolant flush
  • 90k: adds timing belt (if equipped), all fluids, full brake service, serpentine belt
  • Exact services depend on your vehicle's manufacturer schedule — not universal
  • Staying current prevents compounding failures and protects resale value

Per manufacturer service schedules and ASE maintenance guidelines.

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.
