Description
Very high performance fully synthetic lubricant for all latest generation HD Diesel engines and those equipped with EGR or SCR systems for the reduction of polluting emissions.
PAKELO GOLDEN STAR SAE 5W/30 is a fully synthetic lubricant, developed for latest generation heavy Duty Diesel engines.
The product is a U.H.P.D.O. (Ultra High Performance Diesel Oil) lubricant suitable both for on-road and off-road Heavy Duty Diesel engines of main International OEMs: Mercedes-Benz, MAN, Volvo, DAF, etc..
Thanks to its special additive package and to the selected synthetic base-stocks used, PAKELO GOLDEN STAR SAE 5W/30 satisfies, at the same time, the main European Specifications for HD Diesel engines (truck, buses, earth moving machines, etc.): in particular, it satisfies the European ACEA E7, E4 specifications.
Such performance within one single product means obtaining a key fundamental result that is necessary to unify lubrication when engines have sometimes slightly different requirements.
European OEMs are asked to design engines for long drain intervals. For this reason, it has been designed to meet ACEA E4 and MB 228.5 Specifications, requiring very high detergent lubricants in order to maintaining engine cleanliness (in particular piston-liner coupling).
This technology uses high sulphated ash lubricants but sometimes this is harmful for low emission engine design.
Such low emissions engines usually produce higher quantity of soot and need lubricants with high dispersant properties which allow to maintain soot in suspension without changing of viscosimetric characteristic during service.
To further improve the reduction of polluting emissions, mainly regarding the production of nitrogen oxides, recent specifications have been developed, such as the European ACEA E7.
One of the ways to reduce the production of nitrogen oxides is the adoption of the EGR (Exhaust Gas Recirculation) system. Through the EGR system, part (sometimes also significant) of exhaust gas is made to re-circulate in the combustion chamber. Such particles, by absorbing heat, decrease the maximum temperature that can be reached in the combustion chamber and as a consequence of this the total NOX formation is reduced.
As a side-effect there is an increase of the soot produced in the combustion chamber and is necessary a further improvement of the lubricant performance.
Low emissions engines need lubricants with high dispersant properties which allow to maintain soot in suspension without changing of viscosimetric characteristic during service.
An alternative solution to reduce emissions is to use the SCR (Selective Catalytic Reduction) system. In this case ammonia generated from urea, that comes from a specific tank, is injected into the exhaust gas over the catalyst to reduce the NOx to water and molecular nitrogen. Sometimes, the joint use of particulate traps allows further emissions reduction.
The European Specification ACEA E7 were designed for testing suitable lubricants for this kind of engines (EURO IV and EURO V type). A new chemistry allows to obtain a product with TBN (Total Base Number) ideal to guarantee high detergency with a moderate ash content: in this way the lubricants is compatible with the majority of posttreatment devices.
Nowadays, having lubricant that can satisfy at the same time ACEA E4 and ACEA E7 Specifications means providing product with high technological content.
The particular formula of PAKELO GOLDEN STAR SAE 5W/30 thus provides the following properties:
- Excellent low temperature properties: easy start-ups at very low temperatures to guarantee the lubricant action for all the engine moving parts right from the first working periods and to reduce to the minimum the hazards of wear especially when comparing the product with SAE 15W/40 or SAE 10W/40 Viscosity Grade lubricants;
- Very high thermal-oxidative stability at high temperatures also thanks to the synthetic base stocks used to formulate the product;
- HT-HS (High Temperature, High Shear) value optimized for severe and specific needs of modern Heavy Duty Diesel engines;
- Exceptional viscosity stability obtained also through the use of special shear stable additives;
- Fuel savings (“Diesel Economy”) when compared to SAE 15W/40 or SAE 10W/40 Viscosity Grade lubricants;
- Low formation of lacquers and varnishes at low temperatures and in particular during stop-and-go service;
- Very low volatility of the product results into a very significant reduction of oil losses due to evaporation;
- Very high detergent properties that guarantee cleanness performance and long drain intervals;
- Great control of sludge and oil thickening phenomena also in case of high presence of soot and deposits;
- Excellent wear control in every working and ambient temperatures;
- Good compatibility with gaskets;
- Excellent pumpability at low temperatures of used oil too.
Application Fields
