Came across "ran up" oil additive today, and there seem to be lots of dyno runs on different forums that show this stuff actually improves power by 5 to13 HP.

Could this really work or just snake oil?

 

Seems less clear with other additives since there is not dyno evidence. But with Ran Up, I found at least a half dozen dyno tests to support the claim of increased HP. Have a look..

 

That article sounds like the Slick50 ad back in the day! Here is what I found on wiki... I used slick 50, it never hurt my engine but at the same time I do not know if it helped. If you want more ponies from a bottle...buy a Nitrous oxide System!

Wiki...
Although motor oil is manufactured with numerous additives, aftermarket oil additives exist, too. A glaring inconsistency of mass-marketed aftermarket oil additives is that they often use additives which are foreign to motor oil. On the other hand, commercial additives are also sold that are designed for extended drain intervals (to replace depleted additives in used oil) or for formulating oils in situ (to make a custom motor oil from base stock). Commercial additives are identical to the additives found in off-the-shelf motor oil, while mass-marketed additives have some of each.

Some mass-market oil additives, notably the ones containing PTFE/Teflon (e.g. Slick 50)[7] and chlorinated paraffins (e.g. Dura Lube),[8] have caused a major backlash by consumers and the U.S. Federal Trade Commission which investigated many mass-marketed engine oil additives in the late 1990s.

Although there is no reason to say that all oil additives used in packaged engine oil are good and all aftermarket oil additives are bad, there has been a tendency in the aftermarket industry to make unfounded claims regarding the efficacy of their oil additives. These unsubstantiated claims have caused consumers to be lured into adding a bottle of chemicals to their engines which do not lower emissions, improve wear resistance, lower temperatures, improve efficiency, or extend engine life more than the (much cheaper) oil would have. Many consumers are convinced that aftermarket oil additives work, but many consumers are convinced that they do not work and are in fact detrimental to the engine. The topic is hotly debated on the Internet.

Although PTFE, a solid, was used in some aftermarket oil additives, users alleged that the PTFE clumped together, clogging filters. Certain people in the 1990s have reported that this was corroborated by NASA[9] and U.S. universities.[10] One thing to note, in defense of PTFE, is that if the particles are smaller than what was apparently used in the 1980s and 1990s, then PTFE can be an effective lubricant in suspension.[11] The size of the particle and many other interrelated components of a lubricant make it difficult to make blanket statements about whether PTFE is useful or harmful. Although PTFE has been called "the slickest substance known to man",[12][13] it would hardly do any good if it remains in the oil filter.

 

Tomorrow if I have some time I will post links to all the dyno runs.,

 

I think you are all crazy to spend your money on this stuff. i'm selling G.W. Bridge for a 100.00

 

This was on the zMAX webpage...
I've got my reputation to protect and I wouldn't recommend zMAX unless I knew it worked. It penetrates the metal, decreases the friction, cleans the carbon residue out of the engine. Therefore it gives you a more efficient engine and a lot more durability.

Now this was funny...Carroll ain't with us anymore!

 

Will you take $85

 

no 100.00 and its yours

 

But it's a billion dollars to ship right?
