Red Line 60103 SI-1 Complete Fuel System Cleaner - 15 Ounce (4 Pack)

Q: Do you need to change your oil after using this through a full tank of gas?

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?

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?

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?

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
