Boundary Lubrication

Most automotive enthusiasts are familiar with “Fluid Film Lubrication”. We have all poured motor oil into our engines at one time or another and can we all can imagine the slippery substance that all the lubricated moving parts in your engine are riding on. Some of us can even imagine the pressurized hydrodynamic fluid film that the crankshaft journals are riding on. That is the “Fluid Film Lubrication” that we all know. “Boundary Lubrication”, on the other hand, is still a bit mysterious to most car enthusiasts. “Boundary Lubrication” occurs when the Fluid Film of oil cannot support the heat, speed and/or load between two parts any longer. At this instance the two parts actually come in contact with each other. When this happens you must depend on the Boundary Lubrication Additive Package that is in your oil. In Torco’s case, it is our proprietary anti-wear/anti-friction additive system “MPZ” that addresses the very necessary “Boundary Lubrication”. In a nut shell, the additive system causes a chemical reaction on the surface of the two parts at the instance they come in contact with each other. This chemical reaction changes the chemical make-up of the surface and allows the anti-wear additives to form an anti-wear barrier. In turn, this anti-wear barrier prevents the two parts from wearing, scuffing, gulling and even welding on each other when the Fluid Film is no longer present. This is “Boundary Lubrication”
Important Fun Fact: Fluid Film Lubrication accounts for about 5% of all the friction that occurs in your engine. Boundary Lubrication accounts for about 75% of all the friction that occurs in your engine.

MPZ
MPZ "MFR" was originated in 1994, a time when very little concerns were exposed as to engine lubrication chemistry. Without any thought people were putting into there engines all kinds of concoctions just totally inspired by advertizing hype. Because of this, lots of testing was conducted on "MFR". Even as recently as a year ago I dynode "MFR" in a typical diesel formula and it picked up a traditional 1.5%. All through the years we have seen between 1 to 3% increases depending on the many variables at hand. "MFR" is based on a large Dose of phosphorous to set up chemical absorption and polar bonding of the moly to all surfaces in contact with each other. It really doesn't do much until the trigger of metal contact occurs from the full fluid film going away from, "Heat", "Speed", and "Load". More here«

TR-1
Torco TR-1 Mineral Racing Oil is Torco's purpose built Nitro and Alcohol family of oils. The heavier grades in this line of racing oil, 20w/50, SAE 50, SAE 60 and Grade 70, were specifically designed for blown nitro and blown alcohol racing applications. Torco designed the TR-1 formula using a special zero shear polymer that is not affected when it comes into contact with Nitro methane or Alcohol. Along with specially selected mineral base stocks, TR-1 provides unmatched ring seal under the tremendous cylinder pressures that are experienced in these engines during every pass down the race track. In all of our experience and testing with new synthetic materials, we have not seen the performance that we get with our original mineral formulas. Yes, I know it sounds strange but, in this particular segment of racing a Mineral Racing Oil outperforms a Synthetic Racing Oil.

FYI
Torco is the pioneer of blown nitro oils. Bob Lancaster designed the very first blown nitro specific oils for the likes of Don Garlits, Don Prodhome, Kieth Black and many more pioneers of blown nitro racing in the 1950s and 1960s.
