How to improve the performance of my Nissan X-Trail?

I have a Nissan X-Trail and it seems to be running a bit sluggish lately, especially when going up hills. Is there anything I can do to improve its performance?

First, make sure your tires are properly inflated as this can greatly affect performance. You may also want to check your air filter to ensure it is clean and not clogged. If these steps don't help, it might be worth taking your car to a mechanic for a tune-up and diagnostic test.

One simple thing you can do is to regularly change your oil and oil filter. Old, dirty oil can cause your engine to work harder and decrease performance. Another option is to invest in a performance chip, which can optimize your engine's performance and fuel efficiency.
