MARINE ENGINE OILS

PRISTA® MARINE C  oils are designated for low-speed crosshead diesel engines with circulation lubrication, that is to say a closed system intended to lubricate crankshaft bearings, camshaft bearings, etc. PRISTA® MARINE C  ensure rust and corrosion protection at long idle times or downtimes, they wash away wear debris, dirt, scales and oxidation products. These oils do not form stable emulsions with occasionally entrapped water and at last but not least important they prevent deposit formation on the oil cooled surfaces of piston bottom, oil pipelines and crankcase walls. PRISTA® MARINE C  oils ensure practically unlimited service life. They are formulated in three SAE viscosity grades: 20, 30 & 40 and with total alkalinity of 6 mg KOH/g.

PRISTA® MARINE CM oils are recommended for the other type of low-speed marine engines with the so called centralized forced lubrication of the pistons - open system. Only fresh oil enters the cylinders and it almost completely bums there. Just very small quantities run down the cylinder walls into the under piston area and there they are periodically drained as waste. PRISTA® MARINE CM completely meet the basic requirements towards marine oils for high output marine engines burning residual fuels (of high sulfur contents) namely very high TBN - about 70 mg KOH/g and proper thickness - SAE 50.

Prista Oil EAD recommends the following types and grades of lubricants for the other marine diesel engines, namely: medium-speed two-cycle and four cycle, high-speed four-cycle trunk-piston, depending on sulfur contents of the fuel they bum.

All products conform to API CF and meet the requirements of the major manufacturers of heavy loaded marine diesel engines such as: Pielstick, MAN - B&W, MAN Augsburg, New Sulzer Diesel, Wartsila etc.

We also have a special type marine oil PRISTA® MS 9250. It is designated for lubrication of diesel engines that call for oils conforming to the Military Specification MIL-L-9000H. The high alkalinity of the oil allows its problem-free application in engines burning fuel with substantially high level of sulfur.

The following Prista brand lubricants are suitable for application in marine engines demanding motor oils of such quality and grade

This oil is also fit for application in the Detroit Diesel two-cycle diesel engines where the manufacturer recommends the application of API CH-4 performance level lubricant.

PRISTA® Leader TD 15W-40 - Conforms to API CG-4, CH-4/ SJ, ACEA E2-07; E2-04, approved against MB 228.1; MB 229.1,MAN 271, MACK EO-M Plus, Volvo VDS, Allison C^, MTU Type 1, Cummins CES 20071, Cummins CES 20076, Caterpillar ECF1, ZF TE ML 07C/04C, Renault RD/RD-2.

Besides the a.m. primary lubricants, the following supplementary lubricants are also suitable for marine applications:
