Hello, everyone. I am brand new to Chevy vans and to this forum. I've just bought a 1984 Fleetwood Jamboree which sits on the same year Chevy G30 van. I got it basically for free because it hasn't been run in a few years and is in absolutely terrible shape. I'm going over in a day or so to try to get it running and I hope you all can offer some suggestions and answer some questions:

1: How much and what type of engine oil?
2: Which type of radiator coolant?
3: What is the preferred gasoline?

I'm planning on replacing the battery, changing the oil and coolant, and seeing what happens. I'll be prepared with all new belts as well. Can you suggest anything else?

Thanks!
