today's typical marine fuels:

AmergyR 222 fuel oil conditioner, a premium blend of solvents, dis- persants, surfactants, and deter- gents, is designed to minimize the effects of fuel instability and incom- patibility;

AmergyR 1000 combustion im- prover, a product containing no metal, is designed to promote the complete burning of hydrocarbons contained within fuel, ensuring the release of the maximum thermal energy possible during combustion;

AmergizeR deposit modifier/com- bustion improver, contains ingredi- ents which promote more complete combustion and also reduce depos- its and corrosion in combustion spaces.

Drew's international network of service technicians provides added value to each chemical purchase through support programs. One such program is PACE™ fuel evalu- ation which provides comprehen- sive analyses of the chemical and physical properties of bunker fuels, with follow-up recommendations to ship operators.

EXXON

Exxon Company, U.S.A., markets several lines of quality marine lu- bricants. Exxon's marine lubricant line includes De-Mar 17, an LMOA

Generation 5 heavy duty crankcase lubricant for both main and auxil- iary diesel engines. Zinc-free, high- detergent De-Mar 17 has a 17 TBN and is non-corrosive to silver bear- ings. It is accepted by all the major marine engine manufacturers and has been proven in Caterpillar 3601 and Detroit Diesel 6V92T engine dynamometer tests.

The latest Exxon generation of marine diesel lubricants, the

Exxmar line, exceeds the perfor- mance requirements of low- and medium-speed diesel engines under todays conditions and has more than an adequate margin for future needs over the next several years, accord- ing to Exxon.

Combined with excellent wear performance, its standards of clean- liness are high with good overall control of deposits, even when oper- ating on higher viscosity lower-grade residual fuels. Lower TBN Exxmar products are specifically meant for use in earlier model diesel engines.

The high load carrying capacity of the Alkaline crosshead system oil is also been proven as an asset for the more demanding power take-off (PTO) gear application.

Other marine lubricants offered by Exxon include: Spartan EP, a non-lead, extreme-pressure lubri- cant for enclosed gears and bear- ings operated under heavy load or shock load conditions; Spartan Syn- thetic EP, a high VI long-life ex- treme-pressure gear and bearing lubricant; Nuto H, an anti-wear hydraulic oil; 1209 Turbine Oil, a rust and oxidation inhibited anti- wear marine turbine oil, MIL-L- 17331-H approved; and Univis N, a line of high viscosity index anti- wear hydraulic oils.

FERROUS

Ferrous Corporation, Bellevue,

Wash., offers both fuel and lubri- cant additives for the marine mar- ket formulated to improve combus- tion or reduce corrosive wear. The additives include:

Gear-Saver lubricant additive improves the lubricating oil's vis- cosity index greatly reducing heat's harmful effects, and adds film strength for better lubricant sur- face retention. Ferrous reports that

Gear-Saver extends the life of gear box and other lubricating systems through better cold start lubrica- tion, reduced friction, lower operat- ing temperatures and improved break-free surface lubrication throughout the system.

Sea-L-Saver lubricant additive is a premium quality lubricant that blends with all petroleum-based oils and fluids, improving efficiency and extending their operating life. It also extends the life of seals in stern tubes, bow thrusters and hydraulic systems.

Fuel-Guard microbiocide is blend of highly active antimicrobial com- pounds for the treatment of stored fuels. Readily soluble in all grades of fuel oil, Fuel-Guard is effective in reducing bacteria, fungi, and yeasts found in contaminated fuels.

BT-8 fuel stabilizer and sludge dispersant is formulated to improved the stability and burnablity of fuels by reducing the formation of resi- dues and sludges. BT-8 is non- metallic and completely ashless.

MP-4 combustion catalyst and ash modifier promotes rapid oxidation of fuels for more efficient combus- tion, and maintain exhaust valves and superheater tubes free of vana- dium and sulfate deposits. Its is readily soluble in all grades of fuel oil and is intended for use in diesel engines and boilers.

HAMMONDS

BioborR JF is a concentrated liq- uid fuel additive from Hammonds

Fuel Additives, Inc., used to elimi- nate Hydrocarbon Utilizing Micro- organisms (HUM) or HUM-Bugs, in all hydrocarbon fuels such as avia- tion jet fuel, kerosene, No. 1 and 2 diesel fuels, home heating oil, ma- rine diesel and bunker C fuels.

Hammond claims that when used on a regular basis, Biobor JF, known as a microbiocide, will maintain fuel quality by not allowing microorgan- isms to grow. "These HUM-Bugs are only mi- croscopic in size, but they're caus- ing serious harm," says Walter

Chatrand, director of marketing for Hammonds Fuel Additives, Inc.

Even though there are more than 250 types of bacteria and fungi that can live in the water bottom of fuel tanks, only fewer than a dozen actu- ally feed on the fuel and produce acid waste byproducts.

If left untreated, the small per- centage of HUM-Bugs can damage diesel-powered ship fuel systems by clogging filters and lines. At the same time, the acid content of their waste byproducts corrodes fuel tanks, pipes, distorts, rubber hoses and seals, and increases wear on equipment by adding deposits to various engine components.

In various case studies, accord- ing to Hammonds, the small cost of using Biobor JF far outweighs the cost of repairing engines or related parts damage. At a recommended maintenance dosage of approxi- mately one-half gallon of Biobor JF for every 5,000 gallon of fuel, the expense of using a biocide costs only half a cent for every gallon of fuel treated.

MOBIL OIL

Recent developments in cross- head engines have targeted in- creased power and fuel efficiency to reduce operating costs. This has resulted in higher temperatures and pressures in the cylinder, which reduce the lubricant's viscosity and increase the loads which it must withstand. Longer piston strokes have greatly increased the amount of surface to be protected and the amount of time the lubricant must withstand the severe cylinder tem- peratures and corrosive sulfur ac- ids.

New Mobilgard 570 provides ex- cellent protection through optimum viscosity at the higher operating temperatures and pressures of these modern engines. It employs new additives with substantially greater thermal stability and through new base oil refining technology, an op- timum viscosity of 21 est at 100 degrees C is attained for best lubri- cant distribution and film reten- tion.

In order to retain additive effec- tiveness at the higher temperatures of today's cylinders, Mobil chemists developed new, more thermally stable additives.

Other Mobil products include the more recently introduced Mobilgard 24 and 42 Series Oils for lubricating medium-speed trunk-piston marine diesels.

These new oils, said to offer longer engine life as measured by time before or between overhauls (TBO), are formulated to overcome a spe- cific, persistent problem with heavy fuel-burning medium-speed marine diesels: contamination of lubricat- ing oil by residual fuel. This usually occurs through inefficient injector operation, fuel pump leakage into the crankcase, or poor combustion.

The new Mobilgard 24 and 42

Series Oils are formulated to reduce the effects of fuel contamination.

This results in improved crankshaft and camshaft cleanliness; reduced piston and piston ring deposits, im- proved piston cleanliness, and longer filter life. Purifier deposits are also reduced. These oils also offer better thermal stability, resistance to oxi- dation and overall engine cleanli- ness, compared with some other oils.

The Mobilgard 24 Series includes grade 30 and 40 oils with a TBN of 30. The Mobilgard 42 Series, also available in SAE 30 and 40 weights, have a TBN of 40. The higher TBN

Mobilgard 42 Series is intended to provide additional alkalinity reserve for engines with low oil consump- tion or low temperature cylinder liners, or which operate on higher sulfur fuel.
