Does an Engine Oil & Filter Change Count as a Service?
An Engine Oil & Filter Change is a vital part of your car’s routine maintenance, but it does not count as a full service. While it helps keep your engine running smoothly, it doesn’t include the full range of checks required to update your service logbook or reset the dashboard service light.
If your car is due for a service, it’s best to opt for either an Interim Service or Full Service instead.
How Often Should You Change Engine Oil?
Most manufacturers recommend changing your car’s engine oil every 7,500 to 10,000 miles, but always check your vehicle’s handbook for the exact interval. Some vehicles display a dashboard warning light when an oil change is due, but others don’t.
Common Signs You Need an Oil Change:
- Dark or gritty oil on the dipstick
- The engine oil level drops quickly
- Louder engine noise than usual
- Exhaust smoke is darker or smells burnt
- The oil warning light is on
- High mileage since your last oil change
Engine Oil Problems to Watch For
1. Engine Oil Sludge
Sludge is a thick, gel-like substance that builds up from degraded oil. It often signals issues like low oil levels or coolant contamination, and can seriously damage your engine if ignored.
2. Engine Oil “Mayonnaise”
A creamy, yellowish substance under the oil filler cap usually means oil is mixing with coolant, often due to a blown head gasket. If you see this, get your car checked immediately.
What’s Included in an Engine Oil & Filter Change?
A standard Engine Oil and Filter Change includes:
- Drain old engine oil
- Replace sump plug washer
- Refill with the correct grade of oil
- Fit a new oil filter
This process keeps your engine lubricated, reduces friction, and improves long-term performance. While it’s a vital part of maintenance, it won’t reset your service light or qualify for a service stamp.
Not Sure Which Engine Oil You Need?
Check your vehicle handbook for oil type, viscosity, and quantity. If you don’t have the manual, tools like Online Oil Finder can help you choose the correct oil for your car.
