High-Mileage Car Servicing: A Guide for Private-Hire and Delivery Drivers

29 May 20266 min read

Why standard service intervals do not apply

Most manufacturer intervals (often 12,000 miles or every 12 months) are written for private cars driven 8,000 miles a year. If you drive for a living, the oil, brakes and consumables wear out at three to four times that rate.

Following manufacturer intervals on a private-hire car is the single biggest reason high-mileage cars break down before they should.

A realistic schedule for working cars

| Mileage | Job |

|--------|------|

| Every 6,000 mi | Interim service — oil, oil filter, top-ups, visual checks |

| Every 12,000 mi | Full service — air filter, plugs (petrol), pollen filter |

| Every 24,000 mi | Major service — fuel filter, brake fluid, gearbox check |

| Every 40,000 mi | Coolant change, suspension inspection |

| Every 60–80k mi | Timing belt and water pump (where fitted) |

High-mileage warning signs

Pedal vibration under braking — warped discs.

Knocking over potholes — drop links or worn bushes.

Sluggish cold start — battery, starter or injector wear.

DPF light on diesels — incomplete regeneration cycles.

Burning oil smell — leaks onto the exhaust, common on older turbos.

Saving money long-term

Keep a service log — it makes the car easier to sell and helps your garage spot patterns.

Replace tyres in pairs across an axle, not one at a time.

Get suspension noises checked early — bushes are cheap, control arms are not.

Wash the underside in winter to slow corrosion.

What we focus on for high-mileage cars

At our Poplar workshop we treat working cars differently from weekend cars. That means quicker turnaround, OE-quality consumables, written advisories so you can plan, and honest conversations about what can wait.
