SWEPCO 303 Premium Multi-Grade Automotive Engine Oil

SWEPCO 303 Premium Multi-Grade Automotive Engine Oil Now meets API SN Plus AND Dexos™ 1 Generation 2. API SN Plus addresses current issues prior to the release of the next engine oil specification update due out in late 2020 or early 2021. The use of turbocharged, direct injection gasoline engines has increased significantly over the last few years to improve fuel economy and efficiency with lighter weight. The higher power density of these engines makes them prone to an abnormal combustion event [...]

Engine Oil Specifications Updates-2019

There is still some confusion and lack of information about which engine oil to use these days and limitations from the OEM’s. Let’s review SWEPCO Engine Oil’s… Specifications they meet and where to be used: SWEPCO 306 … Meets or exceeds API CI-4+ and SM (except for the 5W30 which only meets SL).

Understanding Technical Data Sheets for Oils

Most lubricant suppliers provide a Technical Data Sheet or Sales Brochure that list the typical physical characteristics and typical performance properties of their products. These typical properties provide results to various physical and chemical tests that are performed on the batch of product. A frequently asked question is “What does this result mean? Is it a good value or average?” Reading test results can be confusing. In certain tests, the higher the result, the better the performance. And in [...]

WHY TIMKEN OK LOAD RATINGS SHOULD NOT BE A PRIMARY MEASURE OF EP PERFORMANCE

When reviewing the technical data sheet for a lubricant or lubricant specifi-cations for a piece of equipment, you will often see references to the Timken OK Load test. So what does it mean when one lubricant has a 35-pound Timken OK Load rating and another has a 100-pound Timken OK Load rating? The truth is … it may have very little relevance to the amount of EP protection you are getting. There are basically three reasons for this: First, the Timken Test [...]

Reading Test Results

From time to time you and we run across a competitive product brochure or an OEM (Original Equipment Manufacturer) requirement with test methods that do not follow the standard ASTM (American Society for Testing and Materials) nomenclature or results. There are a number of different standards in place such as: the German DIN (Deutsche Industrie Norm), ISO (International Organization for Standardization), and SASO (Saudi Standards. Metrology and Quality, Org) to name a few. This makes reading test results, especially for [...]

Lubricating Electric Motors

Lubricating Electric Motors Electric motors contain bearings that require lubrication. Most electric motors use grease. Ideally the grease should have: dropping point above 204°C (400°F), low bleed characteristics, excellent resistance to high-temperature oxidation, and good anti-wear properties. Typical thickeners include lithium, calcium, bentonite, and polyurea. One of the biggest issues is that these thickeners are not compatible with each other which will cause problems and bearing failure if greases are mixed randomly. If the bearing size is known or can be determined, the amount of grease [...]

L.E.T.S.

L.E.T.S. Acronyms are everywhere and are part of everyday life. L.E.T.S. is a very important acronym in the world of lubrication, as it describes the critical information needed to make a product recommendation for that application. LOAD; What are the load requirements? Is the load constant or is shock loading involved? Is the load light or heavy? This information is vital to the long-term performance of the recommended product. ENVIRONMENT; Is the equipment in a clean dust free environment or outside? Is the application [...]
