Is associated with oils that reduce gear scuffing in older high-performance cars. It may contain anti-wear and very mild EP agents, and usually includes fatty additives for worm gears. This service designation is obsolete. The designation API GL-1 denotes lubricants intended for manual transmissions operating under such mild conditions that straight petroleum or refined petroleum oil may be used satisfactorily. Although API designations may be very useful when making general recommendations, manufacturer recommendations should always be consulted to ensure that the lubricant being considered is not prohibited by that manufacturer. The article "Gear Oil Classification and Selection" should appear in the box below, but if you do not see it, you can download it here. It also recognizes that some lubricants are suitable for a wide range of operating conditions and may be recommended for more than one service designation. Archive > 1995 > May/June 1995 > Gear Oil Classification and Selection. Download our printable cheat sheet with BMW, Fiat, Ford, etc. But with the advances in technology, synthetic hydrocarbons (PAOs) and polyglycols show very … This designation is recommended for use in some manual truck transmissions. The base oils can be either mineral oil, a synthetic or even in some cases a combination of the two. These are Mack GO-J+ and Volvo 97310, although these numbers change every few years. download the PDF file. This designation is still widely used for EP gear oils. Keywordslubrication, lubricants, oil, synthetic oil, additives, basics, gear fundamentals. Friction modifiers and extreme pressure additives shall not be used. You can download API's Publication 1560 on gear oils for more detailed information. API began licensing oils against the SN PLUS classification on May 1, 2018. The American Petroleum Institute (API) service designations are based on the type of service in which components will be used.
The designation API GL-3 denotes lubricants intended for manual transmissions operating under moderate to severe conditions and spiral-bevel axles operating under mild to moderate conditions of speed and load. No biggie... you can click here to The designation API GL-6 denotes lubricants intended for gears designed with a very high pinion offset. The manufacturer's specific lubricant quality recommendations should be followed. 1 shoes that a gear oil is a combination of a base oil and specific additives.

Refers to the type of service characteristics of automotive type worm gear axles operating beyond GL-1.
Frictional modifiers and extreme pressure (EP) agents are not used. Fig. Viscosity Tables – Measurement data. Describes the type of service characteristic of manual transmissions and spiral bevel axles operating under moderately severe conditions of speed and load beyond GL-2 but below GL-4. The higher an oil's GL-rating, the more pressure can be sustained without any metal-to-metal contact taking place between transmission components. As in the past, the primary lubricant used for gearbox lubrication is mineral oil. Summary Today gear drive operations have several options when selecting the proper lubricant for their gearboxes.
Relates to the type of service characteristics of gears, particularly hypoid gears operated under non-critical, moderate speed, shock load; high speed, low torque; and low speed, high torque conditions. The article "Gear Oil Classification and Selection" appeared in the May/June 1995 issue of Gear Technology. Classification of Industrial Gear Oil Types. Mack and Volvo trucks (as well as others) have their own specifications that address some conditions beyond GL-5. Designates the type of service characteristics of gears, particularly hypoid gears in passenger cars and other automotive equipment operated under high speed, shock load; high speed, low torque; and low speed, high torque conditions. Oxidation and rust inhibitors, defoamers, and pour depressants may be added to improve the characteristics of these lubricants. hbspt.cta.load(3951034, 'c99217f3-09e7-4751-bc3a-7739dac44a0e', {}); The How and Why of Lubricant Selection and Consolidation for Rotating Machinery, Guidelines for Determining the Cause of Gear Failures, Product Unboxing - The Conserver® Oil Purification Unit, Product Unboxing - AMETEK Spectro Scientific FerroCheck 2100, Advances in the Analysis of New and Used Lubricating Oils by High-Resolution ICP-OES, The Cost Effective Benefits of a High Performance Kidney Loop System, How to Cost Justify a Lubrication Program. Following are the automotive gear oil classifications: Designates the type of service characteristics of automobile spiral bevel and worm gear axles as well as some manually operated transmissions operating under such mild conditions of low unit pressures and sliding velocities in which straight mineral oil can be used satisfactorily. The designations are utilized by manufacturers to select lubricants for particular gear types and operating conditions. The most extensively referenced industrial oil classification is the one established by ANSI/AGMA (American National Standard Institute/American Gear Manufacturers Association) that classifies industrial gear oils where gear oils are classified into four types as shown in the following table : This page gives an overview of the oil specifications, see also the measurement data of engine oils and gear oils over a wide temperature range. Oxidation and rust inhibitors, defoamers and pour-point depressants may be utilized to improve the characteristics of lubricants for this service. In order to choose the best lubricant for a gear set, the following criteria must be addressed: Viscosity – Often referred to as the most important property of a lubricating oil. For example, most modern gearboxes require a GL-4 oil, and separate differentials (where fitted) require a GL-5 oil. The high temperatures values are determined according to method ASTM D445.
Automotive Lubricant Viscosity Grades: Engine Oils – SAE J 300, Dec. 1999. The article "Gear Oil Classification and Selection" appeared in the May/June 1995 issue of Gear Technology.
