OK Folks, really interesting comments about Redex etc, so I thought I’d start a similar tread. I have recently been recommended an engine and auto box treatment called Prolong, ( http://www.prolong-uk.com/new/index.html ). In one test they treated a car with the stuff, then drained all the oil out and drove around New York all day. The car was fine. So, has anybody on here tried the stuff or does anybody have any comments, positive or negative.
 
MB don't recommend the use of additives. Saw similar test many years ago with Molyslip. Rep had a small test rig with a bearing driven by a electric motor. First ran without coating with Molyslip and of course the bearing siezed. Put in new bearing coated with thin layer of Molyslip and bearing ran without siezing.

See Post #1


Do NOT (NOT NOT NOT) under any circumstances put moly-slip (or anything similar) into an auto box .... or ... for that matter any other type of manual or automatic gear box.
The most likely outcome will be a knackered transmission.

In fact - Do not put any additives into an MB auto transmission.
Use only the recommended auto-trans fluid.

Regarding engine oil - I agree with Post #3
