I'm currently giving my 300D a steady diet of 6 ounces of Diesel Kleen and 6 ounces of TCW3 at every fill up.

My hope is that the added lubricity will extend the life of my injectors and that the added Cetane boost is doing...well, hopefully something beneficial!

I am wondering if my additives are really helping anything in reality.

What do you guys use in your MB's or what are your general thoughts on my habit? I figure I am spending about a $1.70 per fill for this.

Thanks
