Has anyone used the z max oil additive? Supposed to absorb into the metal on the internal engine parts. Sounds good but I am not sure.

Snake oil IMO...I wouldn't put that crap in my 427.

LOL. I agree with additives, not this one though.....

I use Z max almost every time I change my oil, I have used it for several years on multiple cars. I use to have a car that used a lot of oil, started using Z Max and it quit smoking oil and the car ran so much better. I believe it works and will continue to use it. I use the oil and fuel mixture. It has been around for a long time and the crazy part is they offer you a 200, 000 mile powertrain warranty if you use it every time you change your oil or like every six months. Not sure if they still do or not though. I recommend it.

Z-Max is snake oil. If you do some research on it you will see that they were ordered by the courts to stop making false performance claims in their advertising. I wouldn't put it in my lawn mower.

So much for CS's credibility.

Snake oil or not, I used it in my C5 with H/C and it dramatically quieted the valve train down in that car. I am using it in my Z. I figure with all the valve issues people are talking about, why not. It cannot hurt and may reduce the valve guide wear. Guess folks have never considered that. Do what you will, I am running it. I also use BG44K in the fuel to cut carbon deposits. Guess that is snake oil to. To each his own.

I ran Royal Purple and Z Max in my Z since new, changed oil ever 5,000 and wondered if I was throwing away my money, however, at 20,000 + miles I thought I had better get my heads done before some thing went sideways, so I dropped it off at RMP for head and cam mod, all of my valves Were In Spec.

I asked Charlie if he thought that the RP & Z max were the reason, he said I really can't say that, it would need a whole more more study.

Do I think that's the answer, hell!! I really can't say, but I did put a bottle of in after I got it back from Charlie after he did the heads and cam. LOL

Yeah, I don't think it will hurt, 08 z06 with 9800 miles. I currently run Redline 5w 30 with a RP oil filter, runs and drives same as new.

that stuff is crap, if anything just add a 4oz bottle of ZDDP at least that stuff really works as it's been proven.

Now you're sure

Mark200X,

Now you are asking us to believe a US Govt agency. I may take my chances with snake oil. Every time someone from the Govt tells me they are here to help me, something bad happens.

We've had many conversations with our Mobile engineer on this topic. Not Z Max specifically but more additives. If the additive package is not blended correctly, the base oil will not hold the additive package in suspension. The additive package has to be blended and balanced correctly.

Mark2009

Incorrect. I am providing information. It is your choice what to do with it; I don't really have any interest in that one way or the other.

I'm curious .......
So what happens to the additive (I presume ZDDP)? Does it float to the top or sink to the bottom? I must get move around by the flow of oil. So doesn't it get to metal surfaces it is meant to protect one way or the other?

Same here. We also use Mobile products and our rotating machinery engineer hates oil additives for this reason.

I have been pretty curious and about to try Oil Extreme though. Mostly because David Vizard gives it a nod and I know he's a "show me the data" kind of guy and tests everything.

Howie,
It will be circulated but the consistency will not be at a certain PPM on a consistent basis. If it goes to the top or bottom will be dependent on the specific gravity of the additives. Blending is a complex process. Unlike just mixing it in. Mobil is stringent on this. They stress any additives must be blended during the initial process. During the initial addition of additives, the base stock combines the additives in a uniform manner which will keep them in suspension. Mixing does not blend. It actually can harm the base stock.

Thanks for the insight !!
