OilChange plans your next oil change: when it is due from the last change date and odometer, typical US cost ranges by oil type, engine size and service type, mobile mechanic versus quick-lube versus dealer priced with the value of your time, a generic 12-month maintenance schedule, a ranked comparison of quotes you already have, and a draft service request to send yourself. Planning only - it never books, dispatches a mechanic, contacts a shop or verifies licenses; the owner's manual wins.

| Tool | What it does |
|---|---|
oil_change_due | Work out when the next oil change is due from the last change date and odometer, current odometer, oil type (conventional, blend, full synthetic) and driving pattern (normal or severe): due mileage and date, miles and days remaining, overdue flag and the interval used. Use when asking 'is my oil change due?'. Do NOT use for prices; use estimate_oil_change_cost. |
estimate_oil_change_cost | Estimate a typical US oil change price range: oil by type and capacity, filter by engine size class, labor by service type (quick-lube, independent shop, dealer, mobile mechanic with travel premium), disposal fee, city cost tier and add-ons (cabin and air filters, wipers, rotation). Use when budgeting before calling shops. Do NOT use to rank quotes you have; use compare_service_quotes. |
mobile_vs_shop | Compare a mobile mechanic, quick-lube, independent shop and dealer for one oil change: typical cost, your time (drive plus wait, or a hand-off at home) priced at your hourly value, all-in cost, convenience and factory-warranty notes, plus the hourly value where mobile breaks even. Use when deciding where to get it done. Do NOT use for a 12-month plan; use maintenance_schedule. |
maintenance_schedule | List generic maintenance items due in the next months from odometer, vehicle age, miles per month, oil type, driving and engine class: oil, rotation, filters, wipers, brake fluid, battery, coolant, transmission fluid, belt, spark plugs, with typical intervals, due mileage and date and cost ranges. Use when planning a year of upkeep. Do NOT use for one oil change date; use oil_change_due. |
compare_service_quotes | Rank 2-6 oil change quotes you already have by price, what is included (filter, quarts, disposal), oil type stated and matching your need, warranty and rating, with flags for teaser pricing, unstated oil type, missing filter, short quarts, no warranty and late slots. Use when choosing between quotes. Does not verify providers. Do NOT use without quotes; use estimate_oil_change_cost. |
draft_service_request | Draft (never send) a message to a mobile mechanic or shop asking for an oil change with your car's year, make, model, engine, mileage, oil preference, city or ZIP and preferred window, and the questions worth asking: out-the-door total, oil grade and spec, filter, disposal, timing, warranty and payment. Use when ready to contact a provider. Do NOT use to compare quotes; use compare_service_quotes. |
