After the great gas octane debate....What's your stance on injector cleaners?
Do you use off the shelf injector cleaner in your car every now and then? If so what brand do you use and what experiences have you come across?

It is a fact that some injector cleaners can dissolve certain plastics used in the fuel lines, connectors, and pumps. The previous owner of my V12 apparently did, and it was thousands to replace the fuel pump, its casing, and many plastic connectors. The best preventative for avoiding clogged injectors is decent gasoline, replace the fuel filter at the recommended interval, and getting filled IMMEDIATELY whenever possible when the fuel reserve warning comes on, to prevent dirt, junk and water being unnecessarily sucked into the fuel system.

Adding anything to every fill up is unnecessary. It takes a very long time to degrade injector performance and I'm talking about years by my own personal experience.

Yes I know that the cleaners deteriorate the fuel system and gaskets if used too much I just wanted to see if anyone has suggestions. I used lucas treatments on my VW and never had a problem.

I used Techron at 20,000 miles. The next tank my engine rpms started to fluctuate. Don't know if its related or not. But I gave my second bottle to my dad to use in my sl500. I'm not going to do it again, haha.
