Do wind turbines need the oil in their gearboxes changed every 500 hours? No, that's not true: Based on model types and in what geographical areas the turbines are located, oil change intervals can range from three to 10 years.
Y'all do know the renewable energy "wind turbines" Joe talked about holds around 60 gallons of oil each in the gear box, yes 60 gallons, and has to be changed every 500 hours ...

so it runs 10 hrs a day, 50 days, 7 oil changes a year, 420 gallons a year, each,, where ya getting the oil at Joe?? I guess he will buy oil from Saudi Arabia, china or another country ,,,,as long as the united States isn't drilling, What's Joe going to do about that?
Frequent harsh weather conditions and fairly non-stop operation require that wind turbines undergo routine maintenance. And as the Power Engineering news organization notes:
Proper turbine lubrication is an important part of that maintenance.
But changing gearbox lubricants every 500 hours is not part of that routine maintenance.
And while gear lubricant replacement intervals have increased through the years, the 500-hour requirement does not appear to have been valid for decades, if ever. Power Engineering, established in 1896, reported on May 1, 2013, that the replacement interval is measured in years:
