My car has always burnt synthetic, I was wondering if it would be okay to switch to a good regular oil?

Hello, I am Danny.

I have attached a picture of what your vehicles oil specification calls for. Do you mean your vehicle is burning oil?

Your vehicle calls for a synthetic oil so I would not switch to a conventional oil. This will normally lead to an issue and if it does, any possible warranty coverage will not happen if you are not using the proper oil. Plus we just don't want to risk an engine failure so I would stick to the OEM spec.

Here is a guide on how to change oil if that will help as well:

Lastly here is a video on a similar vehicle that will help as well:
