Injector Cleaner...to use or not to use?!?!

[benzboySL500]

Hi,

For SL500 2003 79k miles, can we use the attached injector cleaner?

Any harm to the engine? Has anyone used this before?

Also im told for best results to only mix with half a tank of fuel rather than full? Is that so?

Hi we use forte injector cleaner and products in our work shop with good results, cant see any problem with that.

if you've been using quality branded petrol, then it will not be needed.

My 179,000 mile engine runs perfect on standard unleaded all it's life (never used supermarket fuel).

I never use additives.

Most car manufacturers do offer a 'specced' cleaner which has been approved by them, and is guaranteed not to affect the delicate chemical composition of the cats.

yeh my car has sluggish start so wanted to use the injector cleaner, the blue chem one is very strong, so wasnt sure if it would be suitable for an SL500

There is nothing that it can harm, look at it that way

I have regularly used a cleaner (Millers) over the last few years. As Malc says, can't do any harm and with the mileage climbing on past 120k now,and the engine still running as (or better than) new, inc very little black smoke, I can only assume it's contributed.
Just not convinced it's going to help with poor starting - not a common dirty injector symptom afaik.
Just follow the instructions on the bottle for fuel/additive ratio.
