Do ya'll use engine treatment... Is it worth it? Is it bad for your car? if you do use it, WHAT KIND DO YOU USE?????????????

 

i won't use engine treatment on my new TSX. most of engine treatment were meant for older, high mileage cars. what i heard is that Prolong is bad for the engine, and Duralube shall only used on old engine... they are both corrsive,, i will change the engine oil at 6000-8000km with good dino oil, then start synthetic oil after 11000km. that shall be good enough. if you use good/quality oil on time, i don't see any reason for oil additive...
but i do agree that fuel treatment for removing carbon desposit is need... just my 2c

 

yeah... prolong actually "soften" the metal, so I wouldn't use that on a new car.
