Can I use 80W90 instead of EP90?
80W90 oil is perfectly satisfactory for your purposes in a cement mixer – it can be either GL4 (with very little molybdenum disulfide) or GL5 (with lots of moly-d)… for a cement mixer I’d recommend using the GL5 because you have no brass synchro components for the moly-d to attack.
Is EP90 the same as SAE 90?
When it comes to Gearbox oils, many older vehicles specified EP80 or EP90 weight oils. 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.
What is EP90 oil?
Classic EP 90 is a mineral oil based gear oil containing anti-oxidant, anti-wear and extreme pressure additives to protect against problems due to oil oxidation, gear wear and corrosion.
What is EP 80W90?
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 the difference between SAE 90 and 80W90?
SAE 75W-90 maintains a more consistent thickness, or viscosity, across a wide temperature range. It’s thicker when exposed to high heat and thinner under colder, wintry conditions than 80W-90. The use of 75W-90 gear oil is recognized by OEMs as a contributor to overall fuel economy.
Can I use SAE 90 instead of 75w85?
Our answer: Yes, 75W-85 gear oil can most definitely be replaced by 75W-90.
What is the difference between SAE and EP oil?
The higher the Extreme Pressure (EP), the higher the GL category is. It is important to know that the SAE Motor Oil Viscosity Chart (J300) is different from the SAE Gear Oil Chart (J306). The main difference between GL-4 and GL-5 gear oils is the amount of EP additives.
What is 80W90 gear oil used for?
Application. Gear Oil 80W-90 is designed for use in differentials, both hypoid and limited slip, manual gearboxes, transfer cases and transaxles in passenger cars, light commercials, 4WDs, trucks, construction, earthmoving and agricultural equipment, where this viscosity grade is required.
Can I mix 75W90 with 80W90?
You are fine to mix the two I’d think. No weird additives, just basic Castrol 75w90.
Which is better, EP 90 or 80w90?
Although current day mineral 80W90 is typically AGMA/ANSI 4EP /ISO 150 , in terms of differential components protection ,is weak against pre-J306 monograde EP 90** as originally spec’ed. Note: Current day synthetics 75W90 is typically AGMA/ANSI 3EP /ISO 100 of KV@40C of 90 – 110 cSt. Many of he folks on the MG forums still use EP 90, but ……..
Is the SAE 90 oil the same as the ep90 oil?
I seem to be buying two different oils which have the same application. Can anyone confirm if they are one and the same? No they are not, the sae90 spec indicates the type and viscosity of the oil and is used generally in normal gearboxes where everything is in line.
What kind of oil to use on a 75W90?
Use the fluid that the manufacturer recommends. Motor oil 50 grade is 16.3-21.9cst Gear oil 90 grade is 13.5-18.5cst There is a somw overlap when comparing a 20w50 to a 75w90. If you use a 20w50 for the manual, pick a motorcycle oil. There are several 75w90 GL4 specific MT fluids that can be used….like Redline MT90, Amsoil MTG… Ford/GM..
What can be used instead of SAE 90?
You didn’t specify your application. SAE 90 gear oil is equivalent to 50wt engine oil (SAE 80 = 30wt), so you could always dump that in instead if you want. 15W40 diesel oil is close enough to dump in there. Please don’t use anything but gear oil, like 80W-90 in a gearbox or axle that specifies it.
