Avoid the confusion
If you have a plated LSD diff, best always to use the correct fluid even if slightly more expensive than other similar types.
You want a fluid that is designed for plate type LSD's, (providing that you have a plate type LSD) reduces chatter, prolongs life, and has the characteristics of a low friction loss but at the same time provides high levels of lubrication.
You really require to know what brand of LSD you actually have fitted to be able to make an informed choice of fluids.
