Oil Additives & Oil Fortifiers

SFR has manufactured extreme-pressure oil fortifiers since 1985. These are super-concentrated additive packages that go into the lubricant you already run: they reduce friction and metal-to-metal wear, slow oxidation and deposit formation, and extend the service life of both the equipment and the oil.

The range covers the fluids most likely to fail first. SFR 100 Petroleum Oil Fortifier is the flagship, used in automotive and industrial applications worldwide. GASZOL and D-SOL fortify gasoline and diesel engine oil, GEARZOL covers gear oil, and H-ZOL is formulated for hydraulic systems. ProTecta Synthetic Engine Treatment and Engine Oil Booster handle the consumer and light-fleet side.

Independent laboratories, not SFR, produce the numbers behind these products: WearCheck ferrograph oil analysis has documented wear reductions of 20% and higher on treated equipment, and the line carries ASTM D-2783 extreme pressure, L-38 and KA24-E engine test certifications. Fleets, farms, contractors and industrial plants buy these direct or through SFR distributors worldwide.

ProTecta Synthetic Engine Oil Booster


Why Use an Engine Oil Booster after using an engine treatment? Engine oil and engine treatment additives get used up and become less and less effective over time. Even metal bonding agents wear off between sliding surfaces and under pressure. It is necessary to replenish the additives to fortify your oil. ProTecta has an advanced multi-functional synthetic formula that not only treats the metal but fortifies the motor oil as well. Use with Complete Confidence and Peace of Mind. ProTecta's advanced formula is compatible with petroleum, mineral, and synthetic motor oils and oil additives. Perfect for new or older cars. Will not void new vehicle warranties. (See details of ProTecta's 8 - Year/200,000 Mile Engine Warranty by clicking on the More Detail icon). Contains no chlorinated paraffins, PTFE resins, "moly" or graphite like other engine treatments. Will treat 5 oil changes for cars with 4-5 quart capacity! Read More...

ProTecta Synthetic Engine Treatment


What is ProTecta? ProTecta Engine Treatment is a new technology employing a unique synthetic formula that forms an "intermetallic compound" during the lubricating process, that improves lubrication and protects engine parts from wear. In addition, it contains other important additives such as anti-oxidants and detergents for improving motor oils change interval and cleanliness. Thus ProTecta not only treats the metal but fortifies the oil as well. Use with Complete Confidence and Peace of Mind. ProTecta's advanced formula is compatible with petroleum, mineral, and synthetic motor oils and oil additives. Perfect for new or older cars. Will not void new vehicle warranties. Contains no chlorinated paraffins, PTFE resins, "moly" or graphite as in other engine treatments. Read More...

H-ZOL Synthetic Hydraulic Oil Fortifier H-ZOL is a multi-functional synthetic fortifier engineered for use in most all hydraulic systems. H-ZOL significantly reduces friction and can increase the life of your hydraulic system, as much as four times. H-ZOL is excellent for use in extreme hot and cold environments. Read More...

ProTecta High Mileage Synthetic Formula


What is ProTecta? ProTecta High Mileage Synthetic Formula is designed for vehicles having more than 50,000 miles and SFR or ProTecta products have not been used regularly. High mileage vehicles accumulate deposits that create sludge, causing oil consumption and unsightly smoke. In addition seals can become hard and brittle and leak on to the ground. ProTecta High Mileage Synthetic Formula consists of a highly concentrated detergent/dispersant and anti-wear booster package to clean deposits and reduce wear, thus extending the life of your engine. Protecta conditions seals to prevent leaks. ProTecta High Mileage Synthetic Formula has been tested over a grueling (100,000 mile field trial) with outstanding results. ProTecta actually improves fuel economy and its advanced synthetic formula allows you to extend drain intervals. Use a bottle at least every 6000 miles for optimum results. SFR Green properties: Reduces emissions, stops leaks from leaking into the environment, extend drain intervals reducing the need for more oil resources, and has improved biodegradability compared to conventional lubricants.
