does anybody recommend Zmax oil additive? like does that stuff really work or are they b.s.ing? :confused:
my dad is a mechanic for over 10 years and says full synthtic valvoline or
M.B1 and castrol gtx edge already has alot of additives.
so if theres anyone out there who tried zmax??

I find little purpose to oil additives. Good synth oils already have additives in them, and things like Lucas oil additive has been shown to create air bubbles in a geared application.

I saw you say Luca and got excited...

Yeah like mentioned, synth oil has a lot of additives, it would probably be overkill.

Very true! A former friend (yes former, turned out to be a tool) had some issues with that in his C900, and certainly helped make the motor run worse. It aggravated the bearing noises he was getting.

actually... I was having some valve ticking pretty loud on the 99 9-5 with 180Kmiles... last oil change it got a can of BG MOA and the valve noise is GONE.

I will probably use it again. (every other oil change because it stays in there a while)

So changing the oil before never made it go away.

i got to say that, that Engine Restore stuff works pretty good. my old Vig used to eat a qrt of oil every 800 miles put that stuff in it and it stopped eating oil and runs like a chamop now that dcr99vig has it.....figures...
