I double-checked my manual and it says to not use a spray lubricant that is not silicone-based. So, as long as the spray is silicone-based, it should be OK. What you don’t want to use, and I’ve actually seen this recommended in FB groups and other forums, is a petroleum-based lubricant like Vaseline. That will actually do more harm than good.
As far as what to use, I use Thetford Toilet treatment: https://www.amazon.com/Thetford-Toilet-Lubricant-Conditioner-24-36663/dp/B002NSU0ZW/.
