we have all been watching powerblock and heard of them
seen shelby sittin next to a gt500 ss stage 2 with a bottle of z-maxx
seen the horsepower guys "testing" px3 on dynos
seen the dyno test on sites here people rave up and down about it
but dose it work!
will it actually give you more hp better mpg
or are they just blowin smoke up our tail pipes
is the best way to go a really good oil like mobil1 syn or castorl syn
I generally tend to follow cjben's attitude on engine oil additives...and when I saw Carroll Shelby's ad for Z-max, I thought, "Great...either Shelby is a Z-max wh0re now, or that stuff is the greatest thing since the ball-point pen...now which is it?"
All that crap that was being peddled in the '90s is just that...crap. I don't know why anything that might come down the pike in the future would be any better. But with my luck, the greatest additive for the internal combustion engine will be invented, then marketed...and I'll still be sitting there watching an ad and saying to myself, "Oh, I'll bet THAT'S a bottle of garbage!" I can't win...
Don't you think that the oil manufacturers would add it to their oil if it was that great? Kinda what I've been thinking, but when you do see someone you respect (Carol Shelby) promoting it, you want to see where that fishing lure leads you.
Power block and the like are just infomercials anyway. Z max has it's own great infomercial and I have treated one of the engines I run in my racecar with it. I heated up the bearings in a oven and then let them soak in the Z max. You could see a difference in color where the stuff "soaked into" the bearings, Hopefully, I won't see those bearings again until next fall when I rebuild the engine again and then I will see if the Z MAx had any effect on bearing wear
Well the heat of an engine will "bake" the Z-Max in, Chillmiller is simply duplicating the effect in a "lab setting".
I have read that their (Z-Max) fuel treatment is very good, and it's core ingredients have been used in the aviation industry for decades in one form or another.
Airplane gasoline, with it's much high octane requirement, is much more important in having it's fuel not develop any deposits / moisture, for obvious reasons. Maybe overkill for our engines, but in the correct useage, I don't see where Z-Max fuel treatment would cause any harm in any fuel system.
Has anyone ever subjected any other light oil to the same test as they do the Z-Max. I bet any really light oil would do the same thing in similar tests, not that these test prove anything to me.
Just my opinion only. The only additive I know of that does work is zinc. ZDDP, GM EOS. Gov made manufactures quit using it. Even Rottella took it out. Bad for cat. converters. Brad Penn Racing oil is only one I know that still has it. It's great for cams and flat tappet lifters. The rest, like Lucas etc. will only gain you a little time in worn engines before you are forced to do repairs.
Oh, they still put zinc in oils. It's just that SM rated oils have less now than the previous SL rated oils. Your average SM 10W-30 dino will have 700-800 ppm of zinc. About the same for synthetic. Castrol Syntec 0W-30 is still SL rated, and it has something more like 1000 or 1200 ppm of zinc.
