Q: Temperature gauge goes up and down and I have to replace antifreeze daily

Hello, thank you for writing in. The smoke from the exhaust and the loss of coolant most likely means that your head gasket has failed, and is leaking coolant into the engine. The coolant gets burned up with the air/fuel mixture and is expelled with the exhaust gasses. While the oil is also retained by the head gasket, when you have a leak this bad, it mixes with the engine oil and contaminates it. This will cause the oil to become less viscous and not protect the engine like the oil is designed to. Replacing the head gasket can be a lengthy process due to the difficulty in accessing it.
