Renkert Oil is an authorized distributor of Chevron Base Oils. Chevron has led the industry in introducing new technologies that produce the highest quality base oils. These base oils allow higher fuel economy for passenger cars, better cold temperature performance, longer drain intervals and help protect catalytic converters so they clean the exhaust better. With the constantly rising standards for engine oils, Chevron Base Oils simplify the blender's job to meet those requirements.

Renkert Oil is the authorized Nexbase Distributor for North America since 2003. Neste Nexbase Group III Base Oils are so highly refined that they qualify to be labeled as synthetic oils.

NEXBASE 3000 base oils are top-tier base oils. The main applications are high-performance motor oils and industrial lubricants.

NEXBASE 3000 base stocks have high oxidation stability, low evaporation, excellent low temperature fluidity and extremely low sulphur content.

The use of NEXBASE 3000 base oils in motor oils is growing. New emission legislation is a driver for using better base oils. Latest catalytic converter technologies allow less impurity and therefore better motor lubricants are needed.
Conventional Group I mineral oil based lubricants do not fulfill the latest specifications and NEXBASE 3000 base oils are replacing them in high-performance lubricants.

NEXBASE 3000 base oils are produced in refineries in Finland and Bahrain.

Neste Refinery

Major Expansion

Neste Oil has invested in a new production unit in Bahrain as a joint venture with BAPCO. The unit was successfully streamed in 2011 to produce 400,000 MT of Nexbase 3000. This coincided neatly with rising demand for high performance Group III base oils for both Passenger Car Motor Oils and Heavy Duty Engine Oils. Renkert Oil is responsible for marketing and logistics for the key North American market.

Note: Reduced sulfur is an advantage in lubrication oils, higher saturates yields a more stable oil and higher VI (Viscosity Index) provides a lubricating oil with viscosity that does not change as quickly with temperature – a great property for cold engine starts and consistent lubrication as the engine warms up.

Over the years, lubricant users have been treated to a number of ways to designate viscosity grades of the lubricants used in manufacturing. There are SAE (Society of Automotive Engineers) grades for gear oils and crankcases (engines), AGMA (American Gear Manufacturers Association) grades for gear oils, SUS (Saybolt Universal Seconds), cSt (kinematic viscosity in centistokes), and absolute viscosity. To add to the confusion, two measures of temperature (Fahrenheit and Celsius) can be applied to most of these, not to mention that viscosity might be presented at either 40°C (104°F) or 100°C (212°F).Viscosity Illustration

While all of these have served useful purposes to one degree or another, most lubrication practitioners settle on and use one method as a basis for selecting products. To the new entrant into the lubrication field, the number of options can be confusing, particularly if the primary lubricant supplier does not associate one of the prominent viscosity systems to the product label. To complicate matters, machinery designers must define the lubricant viscosity in such a way that the equipment user understands clearly what is needed without having to consult outside advice.

This points to the need for a universally accepted viscosity designation - one that can be used by lubrication practitioners, lubricant suppliers and machinery design engineers simultaneously with minimal confusion.

In 1975, the International Standards Organization (ISO), in unison with American Society for Testing and Materials (ASTM), Society for Tribologists and Lubrication Engineers (STLE), British Standards Institute (BSI), and Deutsches Institute for Normung (DIN) settled upon an approach to minimize the confusion. It is known as the International Standards Organization Viscosity Grade, ISO VG for short.

You don’t have to listen very long in this field before someone says that viscosity is the most important physical property of a fluid when determining lubrication requirements. So, what is viscosity?

Viscosity is the measure of the oil’s resistance to flow (shear stress) under certain conditions. To simplify, the oil’s viscosity represents the measure for which the oil wants to stay put when pushed (sheared) by moving mechanical components.

This table below is commonly used to cross reference the various measures of viscosity. If you have one viscosity measurement and would like it in another, read across horizontally to find approximate viscosity in another unit measure.
