Thats a pretty good price. I would go ahead and put it in, and see if you need to add the friction modifier, if you have a problem. I put some Royal Purple in mine and have had no problems, with not adding the friction modifier.

He's refering to gear oil, not motor oil.
I'm not sure exactly how to explaing the numbers other then different numbers being different weights of oil.

Multi-weight oils (such as 10W-30) are a new invention made possible by adding polymers to oil. The polymers allow the oil to have different weights at different temperatures. The first number indicates the viscosity of the oil at a cold temperature, while the second number indicates the viscosity at operating temperature.

How did you come to the conclusion that he is referring to gear oil? I being mechanically challenged. I interpreted that being a wierd weight of motor oil I have never heard of!

Im confused as to what you are asking. Are you asking me how i knew he was talking about gear oil. If that I what your asking its because engine oil doesnt come in 75W140 and also would be putting friction modifier into the engine. Plus I have changed the gear oil in the front and rear differentials twice since I have owned my XK and know what oil it takes!

sorry should have been more specific. 75w140 is gear oil for qd2 and probably others. hypoid additive is some special lubricant that should be added to the gear oil to keep the lsd from chattering. for most companies you need to buy the additive. for redline and several others the additive is part of the product
