Marine Lubricants (continued from page 30) needs of all types of marine equip- ment.

For crosshead engines, Texaco of- fers TARO Special, a premium quality cylinder lubricant for large, slow-speed diesels burning residual fuels. It is blended from highly refined paraffinic base oils and oil soluble additives to produce a high alkaline reserve (70 TBN) product with good lubricant film strength. It is approved by all of the major crosshead engine builders. It is spe- cially formulated to prevent corro- sive wear and minimize ring depos- its.

Taro Special EX 85 is a premium quality cylinder lubricant specifical- ly developed to meet the require- ments of Sulzer RLB engines. It has provided excellent performance in field tests and is approved by Sulzer for those applications where an 85

TBN product with a viscosity of 24 est at 100 degrees C is specified.

DORO AR 30 (SAE 30) is a pre- mium crankcase lubricant for large, slow-speed engines. It is blended from highly refined solvent neutral oils and carefully selected additives to produce a moderate alkaline re- serve (6 TBN) oil. This product offers unusually good rust and cor- rosion protection, wear protection and water separation characteris- tics. DORO AR 30 meets the Sulzer requirement for engines equipped with PTO units.

Texaco offers a complete line of trunk piston engine oils for me- dium- and high-speed diesels. The specific lubricant required would be based on the sulfur content of the fuel being used in the engine. TARO

XD oils, with a TBN of 15 mini- mum, are used in engines burning fuel with a sulfur content up to 1.8 percent. TARO DP oils, with a TBN of 30 minimum, are specifically de- signed for trunk type engines uti- lizing fuel with sulfur in excess of 1.8 percent. TARO XD and TARO

DP are available in SAE 30 and SAE 40 viscosity grades. TARO XL 40 (SAE 40) is for use in medium-speed engines where the operating condi- tions or fuel sulfur content requires a 40 TBN product.

All of these oils are blended from carefully refined base oils fortified with specially developed additive packages to give excellent perform- ance even under the most severe operating conditions. They have been extensively tested both in the laboratory and in the field. TARO

XD, DP and XL 40 all offer excel- lent TBN retention and anti-corro- sion properties. They are formu- lated with selected detergent and dispersant additives which mini- mize piston ring deposits, improve overall engine cleanliness and pro- vide long in-service life.

Texaco supports its marine lubri- cants with prompt, efficient techni- cal service and the Texlube used oil analysis program for monitoring the condition of the oils in use.

The marketing of fuel treatments by Unitor Ships Service A/S has recently been dramatically strengthened by the acquisition of supplier Gamlen Chemical Compa- ny. Unitor marine chemicals are now drawn from the combined re- sources and expertise of both Perol- in Marine, long know for its fuel treatments, and Gamlen Chemical

Co. The result is a highly efficient and cost-effective range of fuel treatments, cleaners, and water treatments.

Unitor offers treatment products for such fuel handling system prob- lems as sludge, water contamina- tion, corrosion and bacteria/fungi.

A fuel conditioner such as

Unitor's Fuelcare is effective against sludge formation in unstable fuels. The instability can have been caused by aging or long term heat- ing, or by mixing incompatible fuels aboard.

Sludgy fuels often entrain water, thus by dispersing existing sludge and by preventing incompatibility, water contamination can be re- (continued)
