## Questions & Answers

**Q: What's good for diesel engine 6.7**
A: Dura Lube also makes a Diesel version which works best for Diesel Catalytic and Exhaust systems.

**Q: Can I combine with Garantee to pass**
A: It all depends. Are you trying to pass an emissions test? It may take several times with several different bottles to clean out. Also it depends on how bad your catalytic is. This is not a miracle worker if you have a bad cat. It does a very good job on cats that are not completely packed. Your question is too vague

**Q: I have two vehicles, one with 80k miles and one with 110k miles. They both run fine with no check engine lights. Is this a safe preventative cleaning?**
A: Yes, that would be a good idea I do the same for mine . It’s a cheap piece of mind .

**Q: Donde se vierte el liquido**
A: En el tanque de gasolina
