Hi folks;

I was getting my other vehicle serviced (at dealer) and I noticed they were selling engine conditioners for crankcase, combustion chamber, throttle body, fuel lines, and also for other vehicle components.

My 1999 C230 was used for a lot of city driving (some corrosion on oil dipstick) and it seems to me that "conditioning" may be appropriate if they truly worked and there was no long term damage to seals, bearings, or other.

Your opinions? Are these conditioners useful? Or another form of snake oil? Any type to stay away from?? Any type and make especially recommended?

Appreciate your feedback.

Thanks,
Paul
