Step 2: Call a tow truck. You should not try to drive your car with antifreeze in the oil. Antifreeze can cause the oil to become thick and sludgy, which can lead to engine failure. Call a tow truck and have your car towed to a mechanic.
Step 3: Have the oil changed. The mechanic will need to drain the oil from the engine and replace it with new oil. They may also need to flush the engine to remove any remaining antifreeze.
Step 4: Inspect the engine. The mechanic will inspect the engine for any damage that may have been caused by the antifreeze. If there is any damage, it will need to be repaired before you can safely drive your car again.
Step 5: Take steps to prevent it from happening again. Make sure that you are always careful when adding fluids to your car. Always check the labels on the containers to make sure that you are adding the correct fluid to the correct reservoir.
