A multi-point inspection is a systematic check of your vehicle's major systems — brakes, tires, fluids, belts, lights, battery, and steering — giving you a prioritized list of what needs attention now vs. later.

• Takes about 15-20 minutes alongside another service
• Prioritizes safety items from maintenance items
• Catches problems before they become expensive failures
• Written report so you can plan repairs on your schedule and budget
• Not a guarantee — not a disassembly; it's a trained eye safety sweep

Per ASE-certified technician inspection standards.

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.
