What does API GL-4 mean?
What does API GL-4 mean?
The designation API GL-4 denotes lubricants intended for axles with spiral bevel gears operating under moderate to severe conditions of speed and load, or axles with hypoid gears operating under moderate conditions of speed and load.
What is GL-4 transmission fluid?
Phillips 66® Automotive Gear Oil GL-4 is a multipurpose, extreme-pressure, API GL-4 automotive gear lubricant specifically designed for use in select manual transmissions and in drive axles with spiral bevel gears or with hypoid gears operating under moderate speeds and loads.
What is EP transmission oil?
EP 80W-90 Gear Oil is a mineral oil based lubricant formulated for use in a wide range of automotive, plant, agricultural and industrial transmission systems. This grade has a high level of extreme pressure (EP) additive that provides effective gear protection over a range of temperatures and shock load conditions.
What is 90 weight gear oil used for?
80W-90. The 80W-90 gear oil can be used in extreme pressure conditions and as a lubricant for non-synchronized manual transmissions in heavy duty trucks or buses. This gear oil is recommended for conventional and limited slip differentials.
Can I use 80W90 instead of SAE 80?
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.
Can I use GL5 instead of GL4?
No, the API GL5 rating does not supercede or cover the GL4 rating. It is important to follow the gearbox or diff manufacturers recommendations and use the correct GL rating.
Will GL5 work for GL4?
The main difference between GL-4 and GL-5 gear oils is the amount of EP additives. GL-4 is suitable for hypoid gear service when they are under severe service but are without shock loading. GL-5 is suitable for hypoid gear service under severe service and shock loads and not for use in a gearbox.
What does GL-4 hypoid gear oil do?
GL-4 Hypoid Gear Oil has low pour points and high temp properties to provide lubrication over a wide temperature range. This versatile lubricant contains anti-rust and anti-wear EP additives to provide the corrosion protection in drives and hypoid gears. It is not corrosive to copper, bronze, or other non-ferrous alloy bearings and bushings
What is the viscosity of 75W90 GL-4 gear oil?
Typical Properties API Service Class GL 4 SAE Viscosity Grade (Gear Oil) 75W90 SAE Viscosity Grade (Motor Oil) 15W40 Vis @ 100°C, cSt 15.5 Vis @ 40°C, cSt 82
What’s the difference between SAE motor oil and gear oil?
It is important to know that the SAE Motor Oil Viscosity Chart (J300) is different from the SAE Gear Oil Chart (J306). The viscosity has no relation with the API Gear Oil Classification and should be chosen based on the recommendations from the manufacturer based on the temperatures where you will drive.
What kind of gear oil does Red Line use?
RED LINE MT-90 HIGH-PERFORMANCE GEAR OIL is a full-synthetic ester-based lubricant designed for use in manual transmissions and front-wheel-drive transaxles. This shear-stable formula resists breakdown for extended periods and offers more consistent viscosity in warm and cold temperatures for less gear noise and improved shifting.
