What is EP transmission oil?
Extreme pressure (EP) gear oils are used to minimize wear and scuffing in automotive and industrial applications under high load conditions, especially where high peak or shock loads are encountered.
What is hypoid transmission oil?
A hypoid gear oil is a lubricant that is designed to operate effectively with hypoid gear designs. Most gearboxes and differentials use hypoid gear designs and the lubricant must contain EP (extreme pressure) additives to prevent wear between the sliding surfaces of a hypoid gear mesh.
What does SAE 90 stand for?
the Society of Automotive Engineers
SAE 90 meaning SAE 90 refers to the SAE class according to which the transmission oil has been classified. This classification is made by the Society of Automotive Engineers. These are monograde oils which are mainly used at temperatures above freezing point.
What is SAE 90 equivalent?
An SAE 90 gearbox oil is roughly the same viscosity as an SAE 50 engine oil. Most manufacturers now offer EP80W/90 oils in place of both EP80 and EP90. In viscosity terms, this is analagous to using a 20W/50 engine oil in the sump, and will do no harm.
Is EP 90 the same as SAE 90?
Classic Gear EP 90 is a mineral SAE 90 transmission oil. The product is suitable for use in manual transmissions and other transmissions in classic vehicles that require a medium single-grade oil with extreme pressure protection that meets the API GL-4 specification. On Order.
What is 90 gear oil used for?
manual transmissions
Gear Oil GL-5 SAE 80W-90 gear lubricant is recommended for use in spiral bevel and hypoid differentials, power dividers, and oil-lubricated steering axle wheel bearings, and suitable for use in manual transmissions.
Why are hypoid gears used?
Hypoid gearings are used in power transmission products that are more efficient than conventional worm gearing. They are considerably stronger in that any load is conveyed through multiple teeth simultaneously. By contrast, bevel gears are loaded through one tooth at a time.
Is 80w90 an hypoid gear oil?
GEAR OIL HYPOID SAE 80W/90 is a high-pressure gear oil that can be used wherever very high levels of stress occur, such as in cardan joints, hypoid gears etc.
What oil can be used instead of SAE 90?
Yes it is the same… close enough anyway. SAE 90 gear oil is equivalent to 50wt engine oil (SAE 80 = 30wt), so you could always dump that in instead if you want. What kind of oil do you use on a Yamaha outboard engine? The working speed of and outboard engine is much greater due to the resistance of water. So you should use Yamaha lower unit oil, instead of an ordinary automotive oil, which is specially made to help lower unit work efficiently.
What is the viscosity of SAE 90 gear oil?
These gear oils are labeled “multigrade” by the SAE, which provides a rating for the oil’s low- and high-temperature viscosity. For instance, SAE 80W-90 gear oil has a low-temperature rating of 80 and a high-temperature rating of 90. As mentioned previously, gear oil viscosity numbers are not directly comparable to engine oil viscosity numbers.
What is SAE 90 staight mineral oil?
What is SAE 90 Mineral Oil? Super S GL-1 Gear Oil SAE 90 is a straight mineral based lubricant that is used in automotive manual transmission and gear applications. SAE 90 represents the thickness of the oil which equates to an International Standards Organization Viscosity Grade (ISO VG) 220 as well as an SAE (Engine) 50 weight.
What is SAE 90?
SAE-90 is a lubricant used mainly as gear oil. The digit 90 indicates the viscosity of the lubricant. SAE stands for “Society of Automotive Engineers” which was founded by American Automobile Industry. Viscosity means resistance of a liquid to flow.
