I recently used the BG product with direct feed into my 300CE and it did a marvelous job of perking up the engine (which was running very well before that). I noticed even better engine performance, especially at the lower ranges of acceleration and was much impressed.

I don't know how the piston wall scoring occurs, but there is no proof that the event discussed here was due to the direct feed of Sea Foam? To make that statement, one would have to examine the engine first -- then use Sea Foam or another such agent, and find the scoring immediately after that activity?!

I will continue to use the BG product or perhaps Sea Foam for injector cleaning, unless some positive proof emerges that it can be harmful...... Ben Carter
