have you checked the owner's manual?

How do I find out how much of these fluids to add? All fluid quantities are listed in your owners manual. All fluid amounts for all Subarus cannot possibly be listed here. Break open your manual and find out. Also remember that just because it says (made up quantities for example) you will need 2 gallons of coolant, does not mean you will use 2 full gallons. It's always wise to fill/check/fill/check/fill/check to ensure you do not overfill any fluid level. Use the listed specs in your owners manual as a worst case, then rely on the dipstick or indicator as to how much you have really need. With all fluid fill-ups, check for leaks or top-up fluid levels a day later and with each fill-up or other schedule you feel most comfortable with.

Also keep in mind that if it says (made up quantities for example) you will need 2 gallons of coolant (or whatever fluid), that you won't necessarily see 2 gallons come out when doing a fluid swap. The amount leftover in any fluid swap is taken into consideration by SOA engineers, so draining for days, performing a "flush", or using unusual methods to get every last drop out is not necessary.

I have already checked my manual, and it does not specify how much(quantity) differential fluid. It specifies what grades of fluid to use in different climates, but not how much is needed. I am having my mechanic do it, and I am supplying the fluid. I need to know ahead of time how much to bring with me.
