Built for reciprocating compressors — the ones that make water every day. Protects the pump, keeps the compressor running better, and drains the condensate off so the oil keeps working.
Every certified motor oil meets the same specification, and nothing pays anyone to go past it — the rules let a brand say “exceeds,” never by how much. The base oil is the only real difference you can buy. SFR adds what no specification asks for: an extreme-pressure barrier on the metal, plus more corrosion protection and more detergent.

COMPREZOL's extreme-pressure agents coat the pump — the part of a compressor that wears — protecting it and extending its life. A pump that is not wearing runs smoother and more reliably, so the compressor operates better and stays in service.
COMPREZOL is a synthetic based oil fortifier with special extreme pressure agents to protect and extend pump life. Compressors condense moisture, which can be a big problem as corrosive wear takes place 10,000 times faster than mechanical wear. COMPREZOL is highly fortified with a corrosion inhibitor as well as a de-emulsifier to protect against moisture. The de-emulsifier allows the oil and water to separate freely so that any condensed water can be drained off, and the oil is still suitable for continued use.
COMPREZOL works best in reciprocating compressors. It is also used in rotary screw and centrifugal units; call us on those so we can match it to the machine.
Comprezol should be used in rotary screw, centrifugal, and reciprocating compressors at 1½ oz per quart (5%) the first time and 1 oz per quart (3%) at each change after. Comprezol is compatible with most lubricants, but caution should be taken with glycols. When glycols come into question please call for technical assistance due to the large number of different applications.
Gallons and Five (5) gallon pails come with a one-ounce pump for easy measuring. Gallons also have a view stripe with measuring grid in ounces on the label for measuring larger quantities for quick use.

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.
Compressors are one of the most neglected pieces of equipment in a shop or business. Due to the devastating effects of water that condensates in a compressor this is an area that one should treat first to extend the life of the compressor. "Corrosion wear takes place 10,000 times faster than mechanical wear." Comprezol protects the pump with a special extreme pressure coating so that the pump will last a very long time. It also contains special de-emulsifiers to separate the water from the oil so you can drain off the water and continue using the compressor oil.
