I am curious what everybody here thinks. I want to know if anyone has used Z-MAX. I am also wondering if you think Caroll Shelby actually used this stuff in all of the series one shelby's built?

I know that there is the arguement that if this stuff worked the oil companies would have already snatched up on the idea. But I can say from experience that prolong works. I am just curious if Z-MAX does. Their infomercial (yeah, yeah, I know, you think they will tell the truth?) says and supposedly shows that it cleans the motor also.

So what do you think? Does Shelby use it? Does it work and clean?

 

Tite,

Save your money, and invest it in synthetic lubricant instead of addiditves. Or, void your warranty and dump that crap in. (Same for ProLong.)

Take a close look at all of those late-night infomercials. None of them use science or data to prove their claims. They might look like they are "scientific" with all the charts, tables, graphs, diagrams, and aminations,but there is no real data provided to substantiate their claims. All of them use testimonials from their users to promote the "benefits" of their products. These people probably don't know the difference between a spark plug and an oxygen sensor, but they believe the product is actually doing them some good. (Many people still believe that Catholic priests can do no wrong.)

Carrol Shelby has sold out for a big, phat, paid endorsement. John Lingenfelter is three times the performance builder that Shelby ever though about becoming. Shelby's last "great achievement" was a turbocharged four-banger in a POS Belvidere econobox with a Japanese block. The only thing he ever really did was give people a Mustang 350GT that could almost keep up with a Callaway Chevy with a smaller engine. He certainly isn't a lubrication engineer.

Then again, I could be wrong. I just don't believe that I am.

 

I'll say this about Z-Max. I put the stuff in my MR2 and i did see and feel a difference. My MR2 has about 170,000 miles so it had some engine vibration to it. After i put the Z-Max in it reduced the engine vibration, but did not get rid of it completely and i did see better gas milage. Not much but about 15 miles per tank. I don't think I would put it in my Camaro, but just cleaning your engine with ATF every once and a while seems to help quite a bit.

 

Vader...was the Callaway a vette? If you have an info page on it I'd love to see it..I'm looking right now. A buddy of mine thinks Shelby is *** and the 350GT and 300GT's are like 'THE muscle cars of the era'... I'd just like to prove to him, once again, that Ford sucks.

 

GT500s are nice.... neone from around where i live has heard of tattoos by RC.... my buddie built RC's 67 GT500, one of his tattoo shops is next to my buddies shop... its a nice car... he calls it an "underestimated 350 hp".... whatever...lol its nice ..... and pretty quick i hear... i belive its a 427 big block.

 

Wow..I'm a retard! Not only did I get all the letters and #'s swapped, but I made up a car! Let's try this again. GT350 and GT500. There. Man..I must've been REALLY tired typing that..

 

I hope it's very underestimated! 350 horses out of 427 cubes isn't anything to brag about!!!

 

Yeah, that Shelby in Gone in 60 Seconds was crap too

 

well, as I said before I KNOW that prolong works. Now the way I know is an extreme case and is not an everyday occurance. But regardless, I know it works. I am just wondering if this works and cleans the engine the way they advertise.

I do use synthetic oil and maintain my vehicles well. But if I make a new purchase and do not have the cash or time to rip apart the motor, I like to know I have some insurance. Prolong protects. And VERY WELL I may add. But, I would like to find out if it can actually refresh (clean and lube) the internals as they advertise.

I know Shelby is no Lingenfelter, but he is good. I would say that the series one is a very nicely designed car and probaly is his most recent "great achievement." And I am just really curious whether or not Shelby would actually use this as a standard production additive. It is possible, but is it true?

 

Tite,

If you're currently using a good synthetic lubricant, you're not going to get any better friction reduction nor engine protection anywhere - period.

As a matter of fact, using additives with some types of synthetics is detrimental, and will precipitate the esters and olefins out of the suspension fluid. You might as well just put water in the crankcase instead. These additives might be "safe" with mineral oils, but you'd better know whether you're using a polyalphaolefin or polyol-ester based synthetic before you go dumping in any warranty-voiding addiditves.

Drop an email to your oil manufacturer and ask them about the effects of additives in their products. You might be enlightened.
