Mine holds more because of the TechCo Watt's link cover. I think it's about 2.5 quarts + the friction modifier.
I use the Ford full synthetic gear oil with the Ford friction modifier. Not a fan of Royal Purple but that JMO~
I've been told you fill it up until it starts overflowing from the filler hole. About 3.5 quarts for me. It overflows out of the vent on the top of the axle later, but I don't think it hurts to overfill, it's not a pressurized system.
If it ain't broke, don't fix it. If it is, it's cheaper to replace it with performance parts.
