I put some in my 300sd, for pm, and sludge control.

After putting a few drops, in the gas tank. Starting up the car the exhaust shoots out a bunch of sludge. Kinda like when I did the diesel purge, except a lot more comes out.

When the engine is warm. No more shoots out. But when I let it settle for a day and fire it up. More sludge comes out. Which I think is cool.


But yeah, I was just wondering if this was a good think. And if anyone else has tried this product.
