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?

Discuss.

really...no one has an opinion?

Most anything with Techron should do a good job.

From the owner's manual :

In areas where carbon deposits may be
encountered due to lack of availability of
gasolines which contain these additives,
Mercedes-Benz recommends the use of
additives approved by us for use on

Refer to Factory Approved Service Products
pamphlet (USA only), or contact an
authorized Mercedes-Benz Center for a
listing of approved product(s). Follow
directions on product label.
Do not blend other fuel additives with fuel.
This only results in unnecessary cost and
may be harmful to the engine operation.

I use Lucas Oil gas treatment in the bottle good for a fill up cleans well, but i use it on my Honda Civic =)

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.

Bosch has recommended Techron for many years. They also point out that it there should be no more than two treatments per oil change due to contamination.

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.

Chevron Techron but only one bottle between oil changes, anything more than that is overkill...

I used the Chevron Fuel injector cleaner (20 oz black bottle) in my last tank. 1st time in 2 years.

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 Chevron supreme that should do the trick

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.
