2004 Tundra is about 22+ gallons a fill (on fuel light) of Shell regular fuel and cost about $45 to $50. It gets 15.5 to 18.0 mpg for normal driving.
1985 Truck is about 12+ gallons (gas gauge isn't super accurate so I stop a bit early) a fill of Shell premium, not sure on cost. It gets 17-18 mph on normal driving.
I am trying to get the little toy running on regular fuel again. Pings on anything but quality premium fuel.
