## Questions & Answers

**Q: Can it remove water, like k100d+ ?**
A: I doesn’t say anything on the bottle about it, this is geared more towards keeping the DPF clean, and it worked wonders on my Mercedes ML320 CDI for that, feels like I gained 100hp lol. Realistically probably 30-40ftlb in torque on the dog cleaner. The AR9500 is a good cetane boost, stiction fix, and injector cleaner geared more towards Ford HEUI injectiors on 6.0 and 7.3, but works great in any diesel.

**Q: Can this product be used in seni trucks? D-13 engine to be exact.**
A: yes, Our products work for all diesel engines

**Q: Does this product clean the egr valve as well?**
A: I’m not sure check their web site. I know it cleans everything else.

**Q: Can it be used for Standby Diesel Generator systems?**
A: Yes, all diesel engines
