Almost every vehicle on the road today recommends 60,000 miles with a synthetic fluid unless otherwise noted e.g. towing, differential submerged in water, etc. In that case, some manufacturer recommendations drop to 18,000, 24,000, 30,000, etc.
I am actually a service advisor, but find it to be a pain in the ass to work on my vehicles in the shop. Not only do I lack the time during business hours (I personally oversee services on 120-150 or so vehicles per week) but I hate laying down boards to bring the Mustangs in without scraping the sides to the sliding grates above the pit.

But to follow that up, my mention of 15,000 miles is warranted. I don't bring my manual car out of the garage without beating on it, and even so, it doesn't get many miles put on it. It'll take me 2-3 years to put another 15k on it. I haven't even started it since the 18th or 19th.
