Is Fuel Injection Service Worth It or Just a Rip-Off?
Fuel injection service can be worthwhile for modern GDI engines to remove carbon buildup, but many services are unnecessary or overpriced. For traditional PFI engines, regular gasoline detergents suffice, while GDI engines may require specialized induction cleaning or walnut blasting if deposits are severe. Always consult your owner's manual and be cautious of unnecessary or exploitative services.
