Buy manual transmission fluid online at ATO24

Gear oils are abbreviated with GL which stands for Gear Lubricant. Furthermore gear oil is called transmission fluid. It describes the various transmission oil classes with numbers from one to six representing the resistance of the oil. These classes were introduced shortly API by the American Petroleum Institute. The class API GL - 1 includes gear oils for light applications that are not mixed with additives. They are used in bevel gears, worm gears and non-synchronized manual. Oils class API GL - 2 are suitable for use in moderate applications, they usually contain additives that protect against wear. API GL - 3 oils have also been developed for moderate applications, are not recommended for hypoid gears.

 

Gear oil for matching application

Gear oils with API GL-4 classification, can be used under several conditions. They are suitable for bevel and hypoid gears with small axial offset and are also recommended for non-synchromesh gearboxes. For synchronized manual transmission oils class four is the minimum standard in Europe. API GL-5 gear oils are classified suitable for use under harsh conditions. They are used for lubricating bevel and hypoid gears with large axial offset. In addition they are suitable for use in differentials. Frequently manufacturers use in this type of gear oils various approvals that appropriate oil may be used in this case only in the approved by the manufacturer Gear. This is often found particularly in limited-slip differentials (LS). The specification API GL-6 had been withdrawn, since it was found that API GL-5 gear oils meet the requirements sufficiently.

What does ACEA A3/B4 mean?

ACEA A3/B4 engine oils are often 5W-30, 5W-40 or 10W-30 oils that are usually targeted at modern passenger car gasoline and diesel models from various manufacturers.

ACEA A3/B4 5W-30 and 5W-40 engine oils are usually based on API Group III base oils, while ACEA A3/B4 10W-40 engine oils often contain both Group I, Group II and Group III base oils.

For the ACEA A3/B4 specification, an HTHS viscosity greater than or equal to 3.5 cP is required.

Since 2004, the European ACEA (Association des Constructeurs Européens d'Automobiles) has continued to develop the ACEA A3/B3 specification and revise its requirements:

• ACEA A3/B4-21
• ACEA A3/B4-16
• ACEA A3/B4-12
• ACEA A3/B4-10
• ACEA A3/B4-08
• ACEA A3/B4-07
• ACEA A3/B4-04
