Was that true with the fluid fully heated-up before starting to extract it?

FWIW, I generally drive my car for a minimum of an hour on back roads and highways before fluid changes and run the last third or quarter of an hour in lower than normal gears. That's to ensure higher RPMs and higher fluid temperatures.

I ask because I don't recall my diff fluid appearing at all thick when it was extracted by the mechanic at my shop. However, since I wasn't doing the extraction, I might well have missed that the thickness of the oil was greater than it appeared to be when flowing through the clear extraction tube and into the extractor body.

The diff fluid I'm running is Red Line 75W110 GL-5 Gear Oil.
