What oil does a Ford Limited slip differential take?

Ford Limited Slip Differential Oil
To ensure proper functioning and longevity of a Ford Limited Slip Differential (LSD), it is important to use the correct oil. The type of oil required depends on the specific LSD design. Here are some recommendations based on the search results:
1. Motorcraft SAE 75W-140 High Performance Synthetic Rear Axle Lubricant: All rear axles are filled with this oil, which is part number XY75W140QL or equivalent, meeting Ford Specification WSL-M2C192A.
2. Trans-X Posi Trac Limited Slip Gear Oil Additive: This additive is recommended for limited-slip differentials and can be used in conjunction with the gear oil. It helps modify the frictional properties of the oil and eliminates chatter.
3. Equa-Torque Differential Friction Modifier: Another additive that can be used to modify the frictional properties of the gear oil in limited-slip differentials.
It is important to note that the LSD may require both the gear oil and the additive for optimal performance. The specific volume of additive required may vary, but a general guideline is to add 118ml (4 oz) of the additive.
Please consult your vehicle’s manual or contact a Ford dealer for the exact specifications and recommendations for your specific Ford Limited Slip Differential.
I hope this information helps! Let me know if you have any further questions.

Can I use regular gear oil in a limited slip differential?

Must use Lim Slip oil in the rear diff. As above, LSD diff oil has an additive that allows the clutch packs to slip. If the correct oil is used and the diff still clicks annoyingly on tight turns, usually caused by the clutches sticking, extra additive can be used.

What oil do I put in my Rear differential?

75W90 GL-5 Gear Oil
The go-to gear oil for most differentials.

What kind of oil do you use in a limited slip differential?

DIFFERENTIAL | LIMITED SLIP – What gear oil do you recommend for limited-slip differentials? Using non-synthetic 80W-90 GL-5 will produce optimum performance in our Dura Grip clutch-type units. Learn more about LSD oils, and drivetrain lubrication in general, by watching our “Tech Talks, Oils and Additives” video.

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.

Is a Ford 8.8 differential limited-slip?

The good news is that many of these 8.8 differentials included the Traction-Lok limited-slip differential option, which can be identified by a large, S-shaped clip pressing against the inside of the side gears. This can be seen only with the cover off; without an ID tag, you can’t spot a Traction–Lok from the outside.

What kind of oil does a Ford rear end take?

Rear Axle Oil SAE 75W-85.

Do you need limited-slip additive with synthetic oil?

AMSOIL synthetic gear lubes are limited-slip capable and do not typically require an additional friction-modifier additive. However, depending on the differential’s friction material and degree of clutch wear, chatter can still sometimes occur.

What is limited-slip oil?

Kendall® Limited-Slip Axle Additive Concentrate is a special additive used to modify the frictional characteristics of axle lubricants for use in limited-slip differentials. It helps to eliminate chatter in limited-slip differentials when added to non-limited-slip API GL-5 gear lubricants.

What is the best gear oil for a Ford 8.8 rear end?

Those super 8.8’s. come with 75w85, if you want to stick with the oem spec, however any 75w140 would serve you well.

What gear oil for Ford 8.8 with limited slip?

Added half a bottle of Ford friction modifier, and it shut right up. In a racing application where lockup is more important, I’d be willing to skip it, but not in a daily. Other than that, any major-brand 75W-90 synthetic gear oil should do the trick.
