GEARZOL Synthetic Gear Oil Fortifier
Why the Need for Five Oil Fortifiers Instead of the One SFR 100?
This question gets asked a lot and deserves some attention. Originally when we developed SFR 100 in 1988 the additive market was just developing around extreme pressure agents. EP additives were deemed necessary but not found in most all oils. Gear oil and metal working applications were the only place they were being used.
Thus, most formulations for oil fortifiers were fairly simple as this industry category developed.
Technology has increased at an extremely rapid rate. With highly specialized engines and equipment, customers are demanding greater performance. With this improved performance comes the added stress on the engine or machine.
Marketers in the additive treatment industry have focused entirely on the extreme pressure agents and thus most formulations are based on only one main ingredient, figuring motor oil would suffice in the other areas, such as: oxidation control?the life of the oil, corrosion protection?caused by high heat and contaminants, detergency to keep these high performance engines etc. clean, friction modifiers to aid in metal to metal contact that is not extreme but does cause wear, thermal stability under high heat and heavy loads?called shear stability in the industry.
At SFR we have always looked at every possibility to improve engine and equipment performance. This led to a multi-functional approach to maximize performance. In other words not just concentrating on extreme pressure but all of the lubrication needs. In doing this the more simplistic formulations like SFR 100 had to give way to more specialized and complex formulations. Making only one product to use in all applications could still be done, but certain additives had to be left out, and others might not aid in friction reduction. For example, in an engine if a cracked headliner occurs or a blown head gasket, water and anti-freeze are injected into the motor oil. With motor oil, which floats on water, immediate seizure of the engine is inevitable. With SFR 100, the product was developed to be heavier than water, thus staying on the metal and emulsifying thus mixing with the water and anti-freeze to provide film strength. Though this saved many an engine, in a compressor where water from condensation is manufactured every day, this was not a desirable characteristic. With a compressor you want to de-emulsify so that you can separate the oil from the water and not have to change the oil regularly. As we investigated, we found more and more situations like this. Would it be easier to make only one product? Of course, but with the sophistication of equipment today, we had to look at specializing in each equipment group. This included: Gasoline Engines, Diesel Engines, Hydraulics, Compressors, and Gear Boxes. We found that we could make much more effective products and include more additives when we formulated with this approach.
Testing has shown that by concentrating on one specific category such as gasoline engines, we could make a product to make the gasoline engine perform at its highest level possible. And the same for gear boxes etc. We could even add warranty packages to meet warranty requirements along with our proprietary additives. Thus at SFR we not only concentrate on treating the metal, but the oil as well and for each type of equipment that quite frankly requires different additives. In addition, we have developed synthetic products with improved properties over the SFR 100, which is a petroleum based product. We encourage all of our loyal customers and distributors to move to the synthetic products, which is the future in the lubricant industry when it comes to performance.
I have a limited slip or posi-traction rear differential. Can I use SFR Gearzol?
Yes, in differentials that call for gear oil you can use one (1) ounce of Gearzol per quart of gear oil. Do not overdose as slippage could occur if you put in more than the recommended amount.
Can I use Gearzol in my manual transmission that calls for a GL-3 or GL-4 lubricant for my synchronizers?
No, Gearzol has a GL-5 package and is not suitable for manual transmissions using synchronizers; it is designed for hypoid and spur gears. In this application you should use SFR 100 as it is safe for synchronizers and their bushings. Use one (1) ounce SFR 100 per quart of GL-4 gear oil.
How much Gearzol can I use in my manual transmission that does not have synchronizers.
Tests have shown that you may add up to three (3) ounces of Gearzol per quart of GL-5 gear oil.
Can I use Gearzol in my limited slip differential?
Yes, Gearzol can be used in a limited slip differential or what is called posi-traction. These systems work on intermittent friction, thus we limit the use to 1 ounce of Gearzol per quart of gear oil. Gearzol meets GL-5 the latest automotive warranty specification. Being a synthetic SFR Gearzol offers maximum protection that an ordinary gear oil cannot provide.
