I remain skeptical but have no data, either way, to endorse or condemn.
BaTu...........Year and half later, still a SCAM.....
Unfortunately, Bob (the BITOG quoted above) has lost all his credibility since it has come to light that he is a consultant for, and in the general employ of, the "oil additive industry"Here is BOB IS THE OIL GUY link, which states that ZMax is recommended by GM to help alleviate carbon knock and oil consumption.
BaTu,So Ahh,,, racetek27.... How long have you worked for Zmax You on commission???
Is the "27" your age? (just curious)
If the FCC claims were ultimately proved false, as you're claiming, please provide evidence of that to back up your claims... (this is, of course, something not from Zmax themselves or from the "shills" at BITOG. But rather an independent conclusion, preferably from the FCC)
Dose it exist, or is this just more smoke & mirrors? I certainly haven't followed the story since it came out, but then Zmax isn't putting food on my table
Slickcitystan raises a valid point on why not to use "Oil Additives " per GM's position.This excerpt is from GM TSB #05-00-89-072B dated June 5,2008 and pertains to GM passenger cars models 2009 and prior. Please note the last paragraph!
WHAT NOT TO DO: Engine and Fuel Additives, Alternate Fuels, and "Miracle" Products
Various unproven products with claims to improve vehicle fuel economy have been reported ranging from magnets that align molecules to chemical combustion improvers.
Most products claiming to provide benefits are based on unsubstantiated claims. Those that do present "scientific" results generally either have too little supporting data to be conclusive, have not conducted experiments in a controlled fashion, or cannot be substantiated by anyone else but the product's manufacturer.
The U.S. Federal Trade Commission summarizes results for products tested by the federal government at www.ftc.gov/bcp/edu/pubs/consumer/autos/aut10.shtm. A review of the list shows that the majority did not work, and for those that showed some effect, the benefit was too small to be cost effective.
Harmful Ideas That May Damage Your Vehicle and Increase Emissions
One more recent poor idea to improve fuel economy that should not be attempted is to blend either kerosene or diesel fuel into gasoline. Why? Both kerosene and diesel fuel are distillate fuels meant for use in compression ignition engines, not spark ignition engines. They have very low octane and since they are heavier (higher density) than gasoline, they will cause heavy engine deposits and degradation of engine oil.
Notice: Never put Kerosene or Diesel Fuel in your Gasoline Engine vehicle. This may result in inconsistent performance and permanent damage to your vehicle that is not covered by your New Vehicle Warranty.
Chemicals that are normally used as solvents also should not be used. These include acetone, ketones, and methanol. These solvents can be incompatible with your vehicles rubber or sealing components, and may dissolve the vehicle's paint finish. In the case of methanol, corrosion of metal parts in the fuel system also may occur.
Notice: Never use acetone, ketones, or methanol additives in your vehicle. Some of these solvents may damage or corrode your fuel system. They are also very damaging to the painted surfaces of the vehicle if spilled. Damage to vehicle components that result from non-approved or aftermarket additives and devices are not covered under the terms of the New Vehicle Warranty. The only fuel additive currently approved by GM is GM Fuel System Treatment Plus, P/N 88861011 (in Canada, # 88861012).
WHAT TO DO: Maximizing Fuel Economy/Minimizing Costs
The best fuel economy possible is the direct result of proper maintenance and good driving habits. Listed below are GM's recommendations to achieve the best mileage possible. The first group are things to consider for your vehicle, while the second are tips relating to your driving habits.
^ Tire Pressure - One of the major contributors to poor fuel economy are under inflated tires. Tires low on pressure create drag that the vehicle's powertrain must overcome, wasting dollars in fuel. Always keep your tires inflated to the proper pressure as shown on the vehicle placard. This not only serves to increase gas mileage but cuts down on tire wear, further decreasing your costs per mile.
^ Air Filter - A vehicle that has a dirty air filter can't efficiently draw air into the engine. This restriction forces the engine to expend energy to "breathe" wasting fuel in the process. Change recommendations are found in your vehicle Owner's Manual.
^ Proper Viscosity "Starburst" Rated Oil - Always use the proper viscosity oil in your engine. Oil that has a higher than required viscosity will create more drag on the internal components of the engine, causing more work for it, especially when cold. Each Owner's Manual contains information on the proper type of oil for your vehicle. Look for the "starburst" symbol on the front of the bottle, and the SM rating on the API circle on the back label. If you are in doubt, stop by your dealer for an oil change, and any other services required. Most current GM vehicles are equipped with oil life monitors to further assist on the "when" to change your oil. (Aveo/Wave/Optra/Epica currently do not have oil life monitors).
Notice: GM Vehicles DO NOT require additional engine oil additives. Some additives may cause harmful effects to the internal seals and additionally void the terms of your vehicles New Car Warranty.
So, you seem to be dodging the question..... You know, the QUESTION - have you ever been employed by, or received money from Zmax :devil:Needless to say that I know my product and how it works in engines... very well ! The question is not how long I've worked for zMax but how many years as an experienced engine builder/technician
Including you? After all it was you who resurrected this old thread to say the FCC claim was wrong....BaTu,
Anyone can log onto the FTC site and look up the case as it's public information.
