Car Repair Myths Newcastle Drivers Still Believe

Car maintenance is one of those areas where outdated advice sticks around long after it stops being true, passed from parent to new driver or repeated in forums without much scrutiny. Stobbart & Collins, a car repair and mechanics business in Heaton, hears plenty of these myths from customers. Here's what's actually true.

Myth: You must service your car at the main dealer to keep the warranty valid

Fact: Under UK and EU block exemption rules, using an independent garage for servicing does not automatically void a manufacturer warranty, provided the garage uses parts of a matching quality and standard, and the work is properly documented. Independent garages are often more cost-competitive than main dealers for routine servicing while still keeping a warranty intact.

Myth: Modern cars don't need regular oil changes

Fact: Newer engines are more efficient and some have extended service intervals, but every combustion engine still relies on oil that degrades over time and mileage. Skipping recommended oil change intervals, whether that's time-based or mileage-based according to the manufacturer, increases wear on internal components and can shorten engine life significantly.

Myth: A car that starts and drives fine doesn't need checking in between MOTs

Fact: An MOT is a snapshot of a vehicle's condition on the day of the test, not a guarantee that everything will remain in the same state for the following twelve months. Brake pads, tyres, and bulbs all wear gradually and can fall below legal standard well before the next MOT is due, which is why a mid-term check catches problems before they become a fail — or worse, a breakdown.

Myth: Premium fuel is always better for your car

Fact: Higher-octane premium fuel only makes a meaningful difference in engines specifically designed or tuned to take advantage of it, typically higher-performance models. For most everyday cars, running standard fuel as specified in the handbook is entirely correct, and paying more for premium fuel provides little to no real-world benefit.

Myth: You should let your engine warm up for several minutes before driving

Fact: This was reasonable advice for older carburettor engines, but modern fuel-injected engines warm up more efficiently while being driven gently than while idling stationary. Extended idling actually wastes fuel and can lead to slightly more engine wear than simply driving off gently and letting the engine reach operating temperature on the move.

Myth: If the warning light isn't on, nothing is wrong

Fact: Dashboard warning lights are designed to catch specific fault categories, not every possible mechanical issue. Worn brake pads, low tread depth, or a slow coolant leak can all develop without necessarily triggering a warning light immediately, which is exactly why routine visual and mechanical checks matter alongside, not instead of, the dashboard.
