has anyone used Z-max in there engines and if so did you notice any difference?

 

ive heard it makes the internals of your engine corrode faster, i wouldnt use it

 

Pure snake oil.....

Carroll Shelby must have been hurting for money to endorse that ****.

 

Z Max is a chlorinated parrafinic or napthalene, I don't remember which. Either way, once into the system and exposed to combustion gases, it has a tendency to turn into hydrochloric acid. While the motor oil has the ability to absorb a lot of acids that normally occur, this crap will overwhelm it eventually causing damage to the engine. Anybody that thinks this is good stuff is also someone who would put a cup of Clorox in the oil- works on the same principle of releasing organic fats that are already in the oil.

 

thought it was too good to be true. is there any additive that is safe to use. I've used Lucas additives in my bikes before with good results.

 

What's you take on Conoco's new Liquid Titanuim Formula oils?........

 

I haven't seen the completed product break down on Conocos but I have in Kendalls GT-1 with Liquid Titanium. It looks like this in 0w-20:

VI- 168- obviously in a Gp III base married to an ester binder
Cold pour- -49F that should be good for the folks in extreme cold environments
cSt@100C- 8.7, about average for a 0w-20
HTHS- 2.7 about average for a 0w-20
Phos content- 770 ppms per design formulation
Titanium content - 100 ppms per design formulation
Zinc - 860 ppms per design formulation

This should yield a hair more fuel mileage and I would think lower wear metals in harsh winter cold. Only real world testing will tell the tale. I would prefer to see a little more titanium in the mix but since it's a fairly new technology I guess the formulators would rather sneek up on the max before committing to more and finding faults. All of the testing of oils using titanium have been impressive and I'm looking forward to see what Motorcraft does with it. Most likely it will mirror the above.
