Friend, let's talk before you pour another bottle of that stuff into your tank. I've spent years watching what actually happens inside an engine after certain "fuel injector cleaners" get used, and honestly, most of what's sold on shelves is doing more harm than good — quietly gunking up your injectors while the label promises the opposite. In this video I'm naming the 9 cleaners you need to stop buying immediately, plus the 5 formulas Chinese mechanics have trusted for decades to keep engines running clean past 500k miles without a single injector replacement. Stick around to the end because I'll also show you how to tell the difference between a cleaner that's actually working and one that's just marketing sitting in a bottle — a trick most Western shops never mention because it doesn't sell more product. 🛢️🔧 Wei Mechanic exists to hand you the garage secrets dealerships hope you never find out. #fuelinjectorcleaner #chinesemechanictricks #enginemaintenance #cartips #diycarcare
