Duralube??

[PTP]

Does anyone have any experience/factual knowledge about this Duralube stuff.

They make engine treatments/additives which they say greatly improves the life, performance, and a bunch of other stuff...

If it works, is this stuff only for older cars??

And, how does it compare to the other additatives like Prolong? or STP?
thanks

Hard to say what it really does. I have used the STP on a new dodge
and my Max when it was new about two oil changes in. On my old Dodge I used it the same way and 85k miles later when I sold the car
the oil was as clear in the engine never really dark or broken down even after 3k miles. I guess it reduces heat and adds a protective coating to protect from engine scrapping etc.

For $15 I'll keep using it on my new cars. Let me know what you think.

my opinion is that it is better to just use synthetic oil that trying to add an addative that make the regular oil better.
