What is the difference between 80w90 and 85W140 gear oil?
The viscosity chart rates the 80W90 up to 95 degrees while the 85W140 is rated up to 120 degrees.
Which is better 80W-90 or 85w 140?
Garbage Mechanic. 85w140 syn is the way to go, still better cold flow than regular 80w90 and much better protection.
Is 80W-90 the same as 90 weight gear oil?
80W-90 oil is as thin as an 80W oil when cold, and as thick as a 90W oil when hot. A 90W oil is 90W hot or cold. So an 80W-90 will be a little bit thinner than a 90W when cold, but will be essentially the same when hot. Gear oil viscosity is defined in SAE J306, which has been revised.
What is the difference between 80w90 and 85W90?
85W90 is only flowable down to -12 °C, 80W90 on the other hand down to -26 °C. If your vehicle is regularly exposed to very cold temperatures, we recommend 80W90 transmission oil, otherwise 85W90 can also be filled in. The performance parameters of the oils of both SAE classes are identical in many respects.
What does 85W-140 mean?
The first number of the designation specify the oil viscosity at cold temperature, the second number specifies the oil viscosity at high temperature. For example: SAE 85W-140 oil has a low temperature viscosity similar to that of SAE 85W, but it has a high temperature viscosity similar to that of SAE 140.
What’s the thickest gear oil?
The SAE grading system indicates oil viscosity in simple numbers ranging from the thin oil (10) to the very thick oil (140 or above). Heavier weight, or higher grade oil is more viscous and therefore thicker as it flows between the gears. Light grade oil is ideal for small, fast, polished gears under a light load.
What does 80w 140 mean?
The 80W90 and 80W140 are high performance SEMI-SYNTHETIC GEAR OILS with ANTI- FRICTION TREATMENT. They provide superior lubricity which means less wear caused by friction and improved gear protection at extreme temperatures.
What does 80W 90 mean in gear oil?
The “80W-90” numbers apply to oil viscosity. This oil has two numbers and has two grades of viscosity. ‘W’ refers to winter stability. In this situation, the amount “80” means that the oil operates better at lower temperatures. The second number, that is, 90, indicates how thin the oil must be at 100°C.
What is gl4 gear oil?
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 SAE 90 gear oil?
SAE 90 is a global quality standard for heavy duty gear oils as formulated by the Society of Automotive Engineers(SAE), which defines a high level of performance. Gear oil is a lubricant made specifically for transmissions, transfer cases, and differentials in automobiles, trucks, and other machinery.
Where is gear oil used?
Gear oil is a lubricant designed for use in transmissions, manual gearboxes, differentials, transaxles and transfer cases in your car or truck. Gear oil helps your transmission run smoothly. More importantly, it helps protect critical internal components in your car’s gear systems from wear and heat damage.
