SUPERFLO^®

Cold-Start Protection
Cold-starting your car can damage critical engine parts if they are not adequately and rapidly lubricated. SUPERFLO multi-grades are specially formulated for quick flow to engine components at start-up, providing Protection That’s Fast. Protection That Lasts!™

Friction Reduction
Metal bearing surfaces in an engine appear to be smooth but actually contain sharp, microscopic peaks, called asperities. When two surfaces slide against each other under heavy loads, asperities can penetrate the lubricant film and collide with each other, creating additional friction, which reduces engine efficiency.

The friction modifiers in SUPERFLO provide a stronger oil film and reduce contact between asperities. Two grades—SAE 5W-30 and 10W-30—have demonstrated fuel-saving benefits in the ASTM industry standard engine test. SUPERFLO 5W-30 and 10W-30 carry the API’s highest fuel economy rating, "Energy Conserving."

Grades
SUPERFLO is available in four multi-grades and two straight grades that provide a wide range of viscosities to meet a variety of climatic conditions. The SAE 5W-30 and 10W-30 grades are ILSAC GF-2 certified and are the recommended oils for new American and Japanese vehicles.

Beginning in 1994, most automakers specified the use of ILSAC motor oils in their new car manuals. These oils carry a special seal (shown at left) on the front container labels.

The SAE 10W-40 and 20W-50 grades are formulated for use in engines where extra, high-temperature protection is desired or for engines experiencing high oil leakage or consumption. Consult your automobile owner’s manual for the recommended viscosity grade for your vehicle.

API Categories and Engine Protection
All SUPERFLO grades satisfy API Category SJ, which is the highest quality recommended for gasoline powered vehicles.

The four gasoline engine tests that describe the minimum quality for Category SJ require a high level of protection against sludge and varnish deposits, ring sticking, camshaft and hydraulic valve lifter wear, oil thickening due to high temperature oxidation, rusting, and bearing wear.

The complete engine protection provided by SUPERFLO is the result of top quality base oils plus highly effective additives, including detergents, dispersants, and anti-wear additives, plus inhibitors against oxidation, rust, and foam.

Sludge and varnish deposits are controlled by detergents and dispersants that prevent agglomeration and settling out of minute sludge particles. Contaminants remain suspended in the oil and are drained when the oil is changed. Freedom from sludge and varnish is critical to long life and reduced wear of moving engine parts. The rust inhibitor in SUPERFLO effectively retards the formation of rust in hydraulic valve lifters and other critical parts.

High-Temperature Oxidation Resistance
Prolonged exposure to heavy-duty service at high temperatures can cause some oils to oxidize and thicken to the point that they are barely able to flow. This is called oxidation thickening and has become more common due to trailer pulling, summer turnpike driving, and higher engine temperatures associated with emission controls. SUPERFLO has excellent oxidation resistance, as demonstrated in the ASTM Sequence IIIE engine test, which is designed to determine an oil’s performance under these extreme operating conditions.

Other Approvals
In addition to meeting the requirements of API gasoline engine Service Category SJ, SUPERFLO can also be recommended for applications that call for the lower quality SH, SG, SF, SE, and SC oils.

For vehicles requiring an API CD quality oil, Exxon SUPERFLO Diesel should be used.

Care should be taken to avoid skin contact when handling automatic transmission fluids, and to prevent splashing into eyes. A protective face shield, or splash goggles, should be worn when draining transmissions, especially on the service station lift.

Healthy skin condition depends on cleanliness. Oils and greases in con-tact with skin can result in plugging of sweat glands and hair follicles. This may lead to skin irritation or dermatitis. Accordingly, good personal hygiene should always be practiced. Oils, greases, and other foreign materials should be removed from the skin promptly. Soiled clothing should not remain in contact with the skin. SUPERFLO is readily removed from the skin by waterless hand cleaners followed by washing with soap and water, and a soft skin brush. It can be removed from clothing by dry-cleaning or by washing with laundry detergents.

Where repeated skin contact occurs, protective skin creams such as silicone-base creams, applied to clean hands prior to contact, may be beneficial. If SUPERFLO contact the eyes, flush the eyes with freshwater until the irritation subsides.

WARNING: "Empty" containers retain residue (liquid and/or vapor) and can be dangerous. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose such containers to heat, flame, sparks, or other sources of ignition; they may explode and cause injury or death. Do not attempt to clean since residue is difficult to remove, and even a trace of remaining material constitutes an explosive hazard.

"Empty" drums should be completely drained, properly bunged, and promptly returned to a drum reconditioner. All other containers should be disposed of in an environmentally safe manner and in accordance with governmental regulations.
