i was talking to a guy that told me he increased his gas mileage 4 mpg in his ford ranger. i'm wondering if anyone else has tried this stuff or has any testimony if it works or not. thanks

 

Never heard of it...Is it related to the "Tornado" of the 90's?

 

ok...i read about it. in a word, probably not. it sounds like the slick 50 of the 21st century.

 

Seen it at the auto stores. Never tried it, but like fatalerrorz stated, it looks like a slick 50 type product. I'm sure you may see some very slight benefits, if it works at all. But I don't see 4 mpgs, maybe more like 4 miles per tank.

 

I think your is engaged in wishful thinking or now that he's added it he's suddenly more aware of his driving habits and is being more careful on the throttle (most people do this after getting mileage improvers).

Zmax has been around since 1947, and I seriously doubt some miracle potion made way back then before the advent of modern additives is going to live up to its claims. If some 60 year old cocktail alone could add 4 mpg the auto manufacturing companies would put in the engines from the factory.

According to the Federal Trade Commission the product is merely tinted mineral oil. This may thin out oil and give a slight mileage increase (I doubt it) and .... it can cause damage to the bearings. Not worth spinning a bearing or other engine damage which can occur from running too thin an oil.

"According to the FTC, the CRC L38 test is a standard auto industry tool to measure the bearing corrosion protection properties of motor oils. In February/March 1997, an independent laboratory performed two CRC L38 tests of zMax for Speedway and Oil Chem. In those tests, motor oil treated with zMax produced more than twice as much bearing corrosion as motor oil alone. The complaint also states that the defendants fabricated one "report" from the two test reports, eliminating the bearing corrosion results and all other negative test results, and then used that report and the "official laboratory results" - similarly edited to remove detrimental data results - as sales tools in the infomercial and on the zMax Web site."

I think he'd have better success, and safer too, with a synthetic oil of the right viscosity.

Dayummm...didn't know it would hurt anything. I don't fall for snake oils though. Never have, and never will. Did have a Toyota Corolla one that took a can of that 300-weight oil every couple of weeks to give it enough compression to start...lol

 

Thank you, those are the types of answers i was looking for. i'll stay put.
