I did a Google on your oval and it sure looks like a BGE. If you build a good fire with good hardwood charcoal you will be able to hold a low and slow heat seems like forever and even in the deep cold of winter. I usually cheap out and buy Royal Oak from Canadian Tire. I am sure there is better out there but for the most part RA is OK. The one thing I don't like about RA is that I frequently get about a third of the bag that has very tiny lumps and lots of carbon powder? I guess that is what I get for spending less?
