I've got a golf MK7 tsi at 120k km and wanted to do some preventative maintenance to ensure it runs smoothly for a while. Doing a major service soon and wondering what additives i should use post service.

Liqui-Moly Petrol Engine Intake Decarb - 366g | Supercheap Auto

https://www.amazon.com/Liqui-Moly-20.../dp/B001CZODH8

Looking at these 2 products and wondering if they're beneficial on my car. Not expecting anything as good as a manual clean or walnut blast but they're not too expensive so if i can get some value out of them it'd be worth it.

Cheers
