How can I check if my Vauxhall Astra's engine oil needs to be changed?

I've noticed that the oil indicator light has been on for a while now, but I'm not sure when to actually change the oil. I don't want to damage my engine, so any advice would be greatly appreciated.

To check if your engine oil needs to be changed, locate the dipstick under your hood. Pull it out and wipe it clean. Then, insert it back into the oil reservoir and pull it out again to see the oil level. If it's below the minimum mark, then it's time to change your oil.

Some experts recommend changing your engine oil every 5,000 miles, while others say you can go up to 10,000 miles. However, it's always best to consult your vehicle's owner's manual for the manufacturer's recommended interval.

It's also important to keep an eye on the color and consistency of your oil. If it appears dark and gritty, then it's definitely time for a change. Additionally, if you notice any strange noises coming from your engine, it could also be a sign that your oil needs to be changed.
