performance improves with decreasing base oil aromatics content. But the most significant benefit that the relatively new, very-low-aromatic Group II/III base oils brings is improved oxidation and thermal stability. Many base oil studies have described how an oil’ s molecular composition Mineral Base Oils. The base oil is the foundation of a finished lubricant. A finished lubricant is one that is ready for use and is a blend of both base oil(s) and additives. Remember, the additives formulated into the mineral base oil will alter the properties of the base oil. Excel Paralubes will only load clean railcars or Excel Paralubes base oil residual railcars. As long as the previous content of a customer-supplied railcar was an Excel Pure Performance base oil, any subsequent load(s) can be of any grade of Excel base oil without additional cleaning.

Base Oil is the name given to lubrication grade oils initially produced from refining crude oil (mineral base oil) or through chemical synthesis (synthetic base oil).Base oil is typically defined as oil with a boiling point range between 550 and 1050 F, consisting of hydrocarbons with 18 to 40 carbon atoms. CLASSES OF BASE OILS Base oils are classified by the Ameri-can Petroleum Institute into five groups (see Figure 1) according to their ingre-dients and performance characteristics. Group I base oil stocks contain greater than 0.03% sulfur, less than 90% saturates and have a VI ranging from 80-119. Demand for Group I oils is de- Group I CORE™, complementary and specialty base stocks. Learn about our CORE™ and specialty Group I base stocks, designed to offer broad blending coverage with performance capabilities in applications ranging from engine oils to industrial and marine lubricant. Learn more Petroleum refining - Petroleum refining - Saturated molecules: The simplest of the hydrocarbon molecules is methane (CH4), which has one carbon atom and four hydrogen atoms per molecule. The next simplest, ethane (C2H6), has two carbon atoms and six hydrogen atoms. A whole class of hydrocarbons can be defined by expanding upon the relationship between methane and ethane. Known as the paraffins Largest Base Oil Plant in North America. Motiva's Base Oils are hydrotreated, isomdewaxed, and hydrofinished to produce high VI, water-white paraffinic lube oils. Processing conditions are optimized to produce premium quality base stocks with high saturates and low sulfur. Paraffinic Oil. LubBase® oils are refined by an advanced hydrocracking and catalytic dewaxing process in state-of-the-art refinery facilities.The resulting base oil is highly saturated, water-white color and virtually free of aromatics, polar compounds and sulfur.

In oil refineries, the “crude” oil is subjected to fractional distillation and a number of other processes, which result in different types of fuels, base oils, paraffin,  Official Classifications. In 1993, the American Petroleum Institute (API), categorized base oils into five main groups. This breakdown is based on the refining method and the base oil’s properties in terms of, among other things, viscosity and the proportion of saturates and sulfur content.

Official Classifications. In 1993, the American Petroleum Institute (API), categorized base oils into five main groups. This breakdown is based on the refining method and the base oil’s properties in terms of, among other things, viscosity and the proportion of saturates and sulfur content. Group I base oils are classified as less than 90 percent saturates, greater than 0.03 percent sulfur and with a viscosity-index range of 80 to 120. The temperature range for these oils is from 32 to 150 degrees F. Group I base oils are solvent-refined, which is a simpler refining process. All lubricants consist of a base oil. Normally, lubricants consist of 90% base oil and 10% additives. The American Petroleum Institute’s (API) has categorized base oils into five groups which are specified by the saturate level, sulfur level, and viscosity index. Saturate Level. Saturates are a type of molecule commonly found in base oil. Largest Base Oil Plant in North America. Motiva's Base Oils are hydrotreated, isomdewaxed, and hydrofinished to produce high VI, water-white paraffinic lube oils. Processing conditions are optimized to produce premium quality base stocks with high saturates and low sulfur. These base oils are often manufactured by hydrocracking, which is a more complex process than solvent-refining. These oils have better antioxidation properties and have a clearer color than Group I base oils. Group III. These base oils are greater than 90% saturates, less than 0.03% sulfur, and have a viscosity index above 120. All cooking oils contain saturated fat. Some more than others. Oils that are low in saturated fat are high in unsaturated fats. If you are looking to use cooking oils that are low in saturated fats, you may want to choose safflower, canola, or olive oil.Tropical oils like coconut oil and palm oil are high in saturated fat.
