Ford Ranger Differential Oil
The oil recommended for the Ford Ranger differential is 80w90. However, depending on the version of the gear lube, you may or may not need friction modifier with the LS. Even so, AMSOIL recommends the slip lock additive if you do get chatter. It is also important to note that if you have Traction-Lok limited slip, you should add Ford friction modifier to prevent chatter.
The rear differential fluid on a Ford Ranger should be changed every 30,000 to 50,000 miles, with a recommendation to aim closer to the 30,000-mile mark. It’s also worth noting that the 75w-140 is the newer version of the 80w-90, and it’s what Ford uses in new trucks now.
When changing the rear differential fluid, it’s important to ensure that the vehicle is level before attempting to add fluid to the drive axle, as an incorrect fluid level will result if the vehicle is not level. The proper grade and quantity of lubricant should be used, and the filler plug should be installed after refilling the drive axle housing.
It’s also worth mentioning that some users have used Amsoil 80w-90 in their Ford Ranger, and it’s important to use a new factory gasket together with some gasket sealant when reinstalling the cover.
In summary, for a Ford Ranger, the recommended oil for the differential is 80w90, and it’s important to follow the manufacturer’s recommendations for changing the rear differential fluid at the specified intervals.

Which gear oil is better 75W90 or 75W140?
I think you’ve got your numbers backwards the 75W140 is the heavier (140 vs 90) and for more severe service. It is recommended only for the rear diff and only for heavy towing and continuous use. You shouldn’t go heavier than 75W90 in the front and for normal duty and occasional towing 75W90 is fine for the rear.
What is the difference between 75W90 and 75W140?
So, the difference between “75W90” and “75W140” is that at operating temperature, the 75W140 will be considerably thicker than the 75W90 but at room temperature they will be about the same viscosity.

Is gear oil and differential fluid the same?
Differential fluid, also known as gear oil, is designed for vehicles with manual gearboxes controlled by a clutch, pedal, and stick shift. Manual gearboxes are designed as a two-shaft system, and although this design gives manual cars more oomph, it produces an enormous amount of heat and friction.
What kind of gear oil does a Ford Ranger take?
For most Ford Rangers, you’ll need a hypoid gear lubricant SAE 80W or 90W.
What kind of rear differential fluid does a 2011 Ford Ranger take?
Ford Ranger 2011, SAE 80W-90 Premium Rear Axle Lubricant by Motorcraft®.
What fluid should never be used in a rear differential?
Never, under any circumstances, put engine oil in your differential. This will result in devastating damages to your engine. Engine oil is much different than gear oil, mostly it cannot withstand high pressure. Therefore, engine oil should never be used in place of gear oil.
What is the difference between 75W 90 and 75W 140 gear oil?
75W140 has double the viscosity at 100 C than 75W90. Using it will consume more power. It provides better gear wear protection , but LT230s do not wear their gears, so it is a waste of time. The input spline wear problem has nothing to do with the oil.
What kind of oil goes in the rear differential?
There are two types of differential fluid. One is mineral oil, which is a natural, crude oil-based fluid. The other is synthetic differential fluid, which is created in a lab. As with all synthetic oils, synthetic differential fluid oils can be fine-tuned for optimal performance.
What’s thicker 75W90 or 75W140?
So, the difference between “75W90” and “75W140” is that at operating temperature, the 75W140 will be considerably thicker than the 75W90 but at room temperature they will be about the same viscosity.
