Question Z-max

Hi guys,

Have some of you guys use this Z-MAX stuff on your Subies? I'm just wondering?

I would not put anything besides normal oil in my crankcase. Sometimes an aftermarket oil additive or supplement can do more harm than good.

I wouldnt put that crap in a new car... if it was a old car it would be a different case... Just do regular oil changes and your engine will be fine..

Here's an interesting link about Z-max. Supports the snake oil comment. The trade commission is suing them for deceptive trade practices.

If zMax is anything like Slick 50, then I wouldn't touch it, not even with a 10-foot pole. The original owner of my Typhoon put Slick 50 in it when it had 5,000 miles. All my main bearings were hosed when the truck reached 38,000 miles. Here is a picture of my front main bearing: http://www.whitetyphoon.com/bearing01.jpg

I will never put any oil additive in my crankcase again.

Hi guys,

I'm wondering, if you're using synthetic oil, would that still double the bearing corrosion after Z-max is added? Ain't motor oil and synthetic oil different?

You are still going to get bearing corrosion after zMax is added to synthetic oil. Look at what Slick 50 did to my main bearings after it was added to Mobil 1 synthetic oil. Synthetic oil already does an excellent job at lubricating moving parts. Why take the risk and add zMax to it?

Forget about Zmax, Slick50, Snakeoil, etc. The motor oil that you put in your car already has all the additives, detergents, etc., that your motor needs. Just don't get a race oil formulation, as that is not adequate for everyday use.

Yes, Prolong and Motor-Up are also Snake Oils. You don't need them.

Anyone used Lucas Oil Stablizer? I added 1 qt while doing oil change and engine does seen to be much noise and vibration free.

I looked around, there hasn't been any complians for Lucas stuff yet.

You are probably experiencing the "placebo" effect. You are taking a risk everytime you add something to your motor oil.

ZMax is nothing but colored mineral oil. I have heard a lot about cars having major problems a few thousand miles after it is added. Also transmission additives are the worst, what happens is that they get into the seals and soften them up and for about 2000 - 3000 miles they are great, the transmission is smoother and faster etc. But after that the seals start to expand because they keep absorbing these chemicals and pretty soon they expand to the point where they dont fit right and leak and then your in for a major overhaul. I would assume that the same would apply to engine additives.

If you really want to put something in an engine to improve it a little bit you can put a tablespoon of graphite. This tip was given to me by a F1 race mechanic, supposedly it does wonders for engine lubrication. I tried it in a 90's Tbird and it made quite a difference in engine noise and gas mileage. I have not done it to my WRX as I am not sure what its effects may be in a high compression engine. Dont want to do anything that may risk hurting my baby, I stick to regular oil changes, synthetic oil and the highest octane gas I can find.
