name: vehicle-maintenance-schedule description: "Build a maintenance schedule for your car so it stays reliable and holds value — the service intervals, the DIY-vs-shop split, and the checks that prevent breakdowns and rip-offs. Use when asked for a car maintenance schedule, what maintenance does my car need, how to keep my car running, or am I being upsold at the mechanic. Produces an interval-based schedule keyed to your vehicle and driving, the essential do-not-skip items, DIY vs professional, seasonal checks, and how to spot unnecessary upsells — flagging that your owner's manual is the authority."

Vehicle-Maintenance Schedule

Cars die young and drain money from neglect (a skipped oil change, a worn belt) or from over-servicing pushed by shops. This builds a sensible schedule from your vehicle and how you actually drive, separates the genuinely essential from the upsell, and tells you what you can do yourself — so your car stays reliable and you stop overpaying, with the owner's manual as the real authority.

What This Skill Produces

• An interval-based schedule — services by mileage/time, keyed to your vehicle and driving conditions
• The do-not-skip essentials — oil/filters, brakes, tires, fluids, belts, and safety items where neglect gets expensive or dangerous
• DIY vs. shop — what's reasonable to do yourself and what needs a professional
• Seasonal & condition checks — winter/summer prep and "severe driving" adjustments
• Upsell defense — how to tell a genuine need from a padded recommendation, and questions to ask the mechanic
• A manual-is-authority note — the owner's manual intervals govern; this is a guide

Required Inputs

Ask for these if not provided:

• The vehicle — make/model/year, mileage, and engine type (incl. EV/hybrid)
• Driving conditions — mileage/year, short trips vs. highway, towing, climate ("severe" vs "normal")
• History — what's been done recently, any known issues
• DIY comfort — how much you'll do yourself
• Goal — reliability, resale value, cost control, or all

Framework: Intervals By Manual, Essentials First, Upsells Out

1. Anchor to the manual and driving type. The owner's manual intervals are the base; adjust for "severe" conditions (short trips, extreme climate, towing) which shorten some intervals.
2. Prioritize the safety/expensive essentials. Oil and filters, brakes, tires (pressure, tread, rotation), fluids, and belts/timing components are where neglect causes breakdowns or danger — never skip these.
3. Split DIY and shop. Empower simple tasks (fluids checks, air filter, wipers, tire pressure) and flag jobs for a professional (timing belt, brakes, transmission service).
4. Add seasonal checks. Battery/coolant/tires for winter, cooling system for summer — timed before the season.
5. Defend against upsells. Distinguish manual-scheduled work from "while we're in there" padding; give questions to ask and what to be wary of (unnecessary flushes, premature replacements).
6. Defer to the manual. Present it as a schedule to confirm against the specific vehicle's manual.

Output Format

Maintenance schedule: [vehicle/mileage] · driving: [normal/severe]

By interval

Interval	Service	DIY or shop
[e.g. every X mi/months]	[oil/filter · tire rotation · …]

Do not skip: [oil · brakes · tires · fluids · belts/timing]. Seasonal: [winter prep · summer cooling]. Upsell defense: [manual-scheduled vs "while we're in there"] · ask "[is this in my service schedule / can I see the worn part]".

Your owner's manual intervals are the authority — confirm this against it for your specific vehicle.

Quality Checks

• Schedule is interval-based and keyed to the vehicle and driving type
• Adjusts for "severe" driving conditions
• Highlights the safety/expensive do-not-skip items
• Splits DIY from professional jobs
• Includes seasonal checks
• Gives upsell-defense guidance and defers to the manual

Anti-Patterns

• A generic schedule ignoring the specific vehicle and driving.
• Missing "severe" condition interval adjustments.
• Encouraging DIY on safety-critical jobs beyond skill.
• No upsell defense — accepting every shop recommendation.
• Overriding the owner's manual intervals.

Example Trigger Phrases

• "Make me a maintenance schedule for my car."
• "What maintenance does my 2018 sedan need at 60,000 miles?"
• "Which car jobs can I do myself vs. take to a shop?"
• "The mechanic recommended a bunch of services — am I being upsold?"
• "How do I keep my car reliable and holding its value?"
