I tried this on my 95 4 years ago. It created a disaster all along the oil pan gasket and front plate seals. I had the biggest oil leak in my history.
I drained the new oil, put new oil and ran the Vette until the oil reached 300 F and changed the oil again.
Screw ZMAX, I call the 800 number and insulted them. Carol Shelby can suck on this one too.

That garbage has been proven to actually HARM engines.
Been sued by the FTC.
Here is an excerpt from the FTC site:
"According to the FTC, the CRC L38 test is a standard auto industry tool to measure the bearing corrosion protection properties of motor oils. In February/March 1997, an independent laboratory performed two CRC L38 tests of zMax for Speedway and Oil Chem. In those tests, motor oil treated with zMax produced more than twice as much bearing corrosion as motor oil alone. The complaint also states that the defendants fabricated one "report" from the two test reports, eliminating the bearing corrosion results and all other negative test results, and then used that report and the "official laboratory results" - similarly edited to remove detrimental data results - as sales tools in the infomercial and on the zMax Web site."
As I have said before:
If the stuff is sold on Infomercials palmed off as car shows:
It's garbage.
If the stuff is hyped by some well known gearhead.
It's garbage.
If the stuff makes idiotic claims with vodoo physics to back them.
It's garbage.

I used ZMax in my previous 91 Camaro and I didn't notice any difference in anything.
About 6 months later, I received a letter saying that I was a going to receive a settlement from ZMax from a lawsuit that was filed. A few months later, I received a check for the full purchase price.
