Texaco Lubricants Overview

Finding the right type of grease(s) for your equipment can be complicated since numerous factors can influence suitability including the environment, operating temperatures, operating speeds and load under which the bearings are operating. To make it easier to find the right grease for your requirements, Texaco® has introduced a new portfolio of greases for commercial, industrial and marine applications.

We’ve rationalized our ranges and introduced a new, more consistent naming convention:

New simplified product ranges: Key attributes and example applications:

Base Oil viscosity

When selecting the right grease for your operation, the viscosity of the base lubricant (Base Oil) has a significant part to play. The higher the viscosity of a liquid, the thicker it is and so the greater the resistance to flow.

As a general rule, standard multi-purpose greases using a medium viscosity Base Oil (EP: 150-349 mm²/s @40°C) will cover 75% of requirements, where operations run at a relatively high speed, with low to medium loads and no extreme temperatures. However, for the remaining 25% of application requirements, a different grease is needed.

For high (or very high) load applications which operate at higher (or very high) temperatures and therefore need to run at lower (or very low) speeds, a thicker grease is required with a high (HD: 350-499 mm²/s @40°C) or very high (XD: 500-≥680 mm²/s @40°C) Base Oil viscosity.

In low temperature environments, equipment needs to run at high (or very high) speeds, so require the grease to be more liquid (thinner and less sticky), meaning a low Base Oil viscosity (HM: ≤100-149 mm²/s @40°C).

However, whilst the Base Oil element of the grease, which accounts for up to 95% of the formulation, is an important factor when determining suitability, it’s the addition of thickeners and additives, as well as the manufacturing process, that make the difference.

Thickener

Thickeners combine with the base lubricant to produce the required consistency of the grease. The higher the consistency, the more resistant the grease is to leaking under force.

Thickening agents can be based on ‘metallic soaps’ (such as lithium, aluminium, sodium and calcium), ‘complex soaps’ (where a complexing agent is added to the soap to help improve performance) and ‘non-soap’ (generally used for special applications such as high-temperature environments).

Since it’s the thickener that drives a grease’s suitability for different uses and applications, by providing its main structure and consistency, our new product families are grouped by the type of thickener technology.

NLGI grade

The NLGI grade classifies the final consistency of the grease, as a result of its individual Base Oil/Thickener/Additive formulation. NLGI grading ranges from 0 (and 00, 000) which is very fluid to 6, which is hard.

Additives

All Texaco greases are formulated with additives that help enhance the performance of the Base Oil.

Additives come in the form of ‘chemically inert’ additives (such as polymers or those that can modify tackiness or viscosity) and ‘chemically active’ additives (which can improve anti-wear, anti-rust and oxidation properties, or improve sealability and performance under extreme pressure).

The third type of additives are ‘solids’ which are most useful in protecting heavily loaded bearings from fretting wear, scuffing and seizing. Some can also provide added durability as well as protection under extreme pressure. Types of solid additives include molybdenum disulfide (moly), graphite, calcium carbonate, zinc oxide and titanium dioxide.

With our new Texaco® grease products, each part of the name represents specific information about the product that is essential to your grease selection.
