How do I know if my Vauxhall Insignia needs an oil change?

I just bought a used Vauxhall Insignia and I'm not sure when the last oil change was done. How can I tell if it's time to change the oil?

The general rule for oil changes is every 5,000 to 7,500 miles or every 6 months.

You can also check your owner's manual for the recommended oil change intervals for your specific model and year of Vauxhall Insignia.

Additionally, pay attention to your vehicle's oil change indicator light. If it's on, it's time for an oil change.

If you notice any unusual noises, decreased performance, or dark and gritty oil, it's also a sign that your Vauxhall Insignia is due for an oil change.
