## Questions & Answers

**Q: Do you need to change your oil after using this through a full tank of gas?**
A: No need to change oil.  This is a fuel additive that cleans fuel injectors to better mileage.  Does work.

**Q: Is this ok as y to use with diesel engines?**
A: NO....use the one for diesel (Red Line 85 Plus Diesel Fuel Additive (12 oz.) (Quantity 1)) It is also available on Amazon in several qtys.

**Q: does this also help clean the catalytic converter?**
A: Maybe it cleans fuel system and injectors.
Help clean the CAT? Sorry, I can't answer that question.

**Q: Has anyone tried using this as for an engine flush? What were the results?**
A: No, and why use it as an engine flush? This product was formulated and meant to be used as a fuel system cleaner and it's an effective one, at least in my case.  I've been using in the past 4 years on 3 different vehicles. Best results you'll really notice is using it every 15-20k. Using it more frequently is just a waste. Now, going back to engine flush question, I've used BG EPR.  I used it on my wife's 2010 CRV with 150k and0
