That's why I use Super Tech oil (Wal Mart brand) oil and add a little Lucas in the summer for towing!!! Tried synthetic, mileage didn't get any better, went back to cheap stuff-can't afford Royal Purple!!!

I saw there one test where they put a drop of Z max in the center of a plate and the stuff "Soaked" into the metal. I don't buy it, I'm willing to bet that WD-40, penetrating oil or any other super thin oil would do the same thing. Honestly think its a gimmic.

The engine additive industry is much like the body supplement industry. Unregulated and unproven. Driving right and changing fluids will do much more for any engine then any additive. Don't be a sucker! There is not and never will be a magic pill! That being said, if your engine in dirty (sludged or heavily deposited) clean it and then treat it right.

If someone is going to run Z-max then they also should get fuel line magnets and a tornado for their intake. Throw in a few performance stickers on the windows for good measure.

During the '90s I was a sucker for anything advertised on tv. I tried Slick 50, Dura Lube, Motor-Up, Prolong, and Restore. None offered any improvement in how my engine ran. I must have missed out on the Z-max...I can't recall ever seeing that one.
The only product I did have success using was Casite Engine Tune Up, when added to the gas tank, it cleared up an engine miss and cleaned the spark plugs.
I do recall that none of my engines could never make it past 150,000 miles without blowing excessive amounts of smoke out the exhaust. Since the '90s I quit using oil additives and am having no problem getting over 150,000 miles with little or no increase in oil consumption. Now I am afraid to try anything.
