I liked that it was positioned as an additive rather than a complicated fix, which made it feel easy to try.
What I Looked For Before Buying
Before I decided whether it was worth it, I focused on a few things:
- Whether it was compatible with my engine type
- If it could help with small leaks or worn seals
- How easy it was to use
- Whether it would affect my oil performance
- If it offered good value compared to a mechanic visit
For me, these points mattered because I wanted a simple solution, but I also didn’t want to risk damaging my engine.
