[W126 Coupe] oil additives

[Nathan Goodlet]

oil additives... what is the consensus yes or no 
   
I say definitely NO. Miracle slick-ums are usually one or another type of SALT, which bonds to the metal tenaciously, other than the teflon crap which is a cup of very fine hard plastic flour. BTW, Dupont prohibits the sale of brand name Teflon to any company intending to sell it as oil additive. SOme of the Miracle slick-ums really do work as advertised, but they are  not used by the oil companies because of the potential for corrosion, and some of them say change the oil "at recommended intervals" because any buildup of moisture is VERY BAD with the salt bonded to the metal. Ford indicted one of the miracle lubes on their diesels, they sliced a block up into thin pieces trying to discover why they were perforating between oil and water passageways, expecting to find it was corrosion from the water jacket, but it was actually corrosion from the pil passages into the water jacket.

You don't want anything with any salt in an aluminum engine. Straight dino oil has these engines lasting 300,000 with no ring wear, what would you want to use additives for anyway?
