On my 2017 Newmar Ventana, left aft basement is a plug that when plugged in it engages the engine block heater for cold weather ops. It's a high amp draw so it should be used only when needed for example tonight I'll plug it in for tomorrow's departure.

I've heard of some configuring the OASIS to be an engine pre-heat loop which seems to be different?

What exactly is happening when I plug in the engine heater plug on my Newmar Ventana? Is it coming from OASIS or is it a separate electrical heating system?

I believe it is a separate heating element in the engine block; no connection to Oasis. I also believe that Oasis has a connection to the engine cooling system and that can be used to heat the coach when traveling. Whether you can reverse that cycle and pre-heat the engine with Oasis is unknown to me.

You probably also have a switch on the dash to activate/deactivate the block heater receptacle in the engine compartment...at least, there is in our coach. Be sure to check or your block heater may not be active.
