Best Fuel Injector/System Cleaner

I am considering the following four fuel system cleaners:

1. BG 44K
2. Chevron Techron Plus
3. Red Line Fuel Cleaner
4. Royal Purple Max Clean

Which have you used and which would you recommend?

Thanks

I use both Chevron Techron or Lucas Fuel System Cleaner on a regular basis. Not because I have any particular problem, just as part of my maintenance I do. Also, both are readily available.

I use Techron only because it was the one additive recommended by MB when I owned one. But I have no evidence, subjective or objective, that it is better or worse than any other, or that it works at all, for that matter.

Well, I just bought the Slick 50 Fuel Treatment for higher mileage cars.

It is extremely well rated so I will keep you updated.

Thanks for your help!

I use Techron every 3000 mi. I've used it for years in our previous 2003 Corvette to keep the fuel gauge working, so continued using it in the 650 what with all the injector issues.
