How can I improve my Vauxhall Grandland engine performance?

I've been noticing a decrease in my Vauxhall Grandland engine's performance. What steps can I take to improve it?

Regularly changing the oil and air filter can significantly improve your engine's performance. Also, make sure to keep up with routine maintenance and tune-ups.

Consider adding a tuning chip or upgrading your exhaust system for a boost in horsepower and torque.

Have a mechanic inspect the fuel injectors and spark plugs for any clogs or damage that may be hindering your engine's performance.

If you frequently drive in stop-and-go traffic, consider using a fuel injector cleaner to prevent build-up of deposits in your engine.
