alright, ive been readin z-max and looks like it rteally works, im thinkin of gettin new sparks changin oil, tranny fluid, z-max, checkin everything, whats kinda sparks to work great for 1st gen intrep.
Instead of using some super addative and K-Mart blue light special oil, why not just use good real synth oil?
Heres what you want to use...
Engine oil: Mobile 1 10w30
Oil filter: Mobile 1 or Pure One
Spark plugs: Champion Golds or Coppers (Golds last longer)
Trans fluid: Mopar ATF 4 (get it from the parts desk at your local dodge dealer)
If you really want Z-max, just save the money and go get yourself some mineral oil, that's all it really is. That whole emptying the oil after Z-Max was added and then pumping sand in through the air on their old infomercial?
"I've never seen an engine go through that." No duh, cause no one is stupid enough to flow sand through their engine.
Bottom line: A report by the government a few years ago actually found that Z-Max ended up hurting many an engine instead of improving. Lawsuits were filed, I'm still surprised the product is actually still around.
