Im watching Speed Week...ZMAX..they talk about on how well this product has been tested and works. They even show how well it works on an air cooled aircraft 4 cyl..extended life 50%, along with some hi-reving big blocks. This product supposedly soaks in the metal..helps dispurse carbon deposits..engines, trannies, rear ends and so on..different then other products...showed many samples and torture tests...NOW...dont flame me, just trying to learn and help make my engines live as long as possible. I use in all my diesel trucks a product called Dura Lube, have for years. I have some Ford 6.0's and a 04 Duramax with 153k miles on them, both run like champs. No motor issues and both trucks after about 30k, just pull trailers. I even used the product in the trannies and temp gauges before the trailer pull were about 15-25 degrees cooler on the aftermarket gauges. NOW..I change oil every 5k miles...Keep a stringent maint. sched...dont know if it's luck, or does the product possibly work, and want to know if other people have tried it, and what was the results. Dont know if it would be good for the Merc 700's, thats the reason for the thread. Thanks Jeff

Would it void the Merc warranty?

Hmmmmmmmm just leave it on the lift and not use it would ext. the engine life.lol

First I gotta have a lift that works

All those magic additives are nothing more than a lubricity agent in a suspension. 90% of them are molybdenum disulfide (m2so4) and occasionally there's some tungsten disulfide (wsx). Moly bonds to metals fairly well and WSX pressure bonds so the mechanical processes of the engine will infuse it into the host metal's surface.

This stuff has been around since the invention of internal combustion engines and it does work. It doesn't work miracles though. Both are so fine molecularly that they'll pass freely through an oil filter and would only be detectable if you were looking for it AND knew what to look for. There's absolutely nothing detrimental about any of them, other than they would inhibit proper break-in of a new motor.

A good point, Ive used them on break in, on my second oil change after I had 5000 miles, so my second oil change. The reason now would be on my Merc 700's, I have 21.23/21.32 hours and changed oil at 20.06/20.17 on the first time. So do you feel it possibly works or does not. From my stand point, Ive had great success, and will do it on my 08 6.4 litre after 5k miles as well, just uncertain if it will slightly help, hinder my merc motors. I just dont want to make a mistake..kinda like that thread...std oil vs synthetic oil. Thanks Guys..more comments please. Jeff

I saw that today on 2 guys Garage too. Looked good on TV.

exactly...great show, along with all the others, love Sunday morning from 6-noon...all my shows..

Jeff, are you sure you logged those one hundreths correctly?

No offense, but I wouldn't call Ford 6.0 or a Duramax with 153K miles a success. I can get 200K miles on a chevy 5.3 with the basic valvoline or pennzoil.
