Coleman White Gas/Unleaded Stoves- Cheap, cheap cooking

[MN C Van]

Does the stove allow a very low flame for simmering?

No. About the same as you describe

Its not always simple to extract gasahol from ones fuel tank to fill one of these multifuel stoves. 

Just popped fuel line off fuel rail. Wasn't diff on my particular vehicle.

it is not really cheap either.

Relative propane, even Coleman branded, is, super cheap.
It's so efficient, a gallon will last well over a month of everyday cooking

I hate the waste and expense of the green propane bottles, but I do not fear cooking inside or have to take many precautions. 

I hear you. Whomever the Coleman VP was who got people to switch over to bottles is probably sitting in the south of France woth printer cartridge and K-Cup guy!

That it doesn't do.
