Does steel seal work for 4-cylinder engines?

Steel Seal is designed to work in a variety of engines, including 4-cylinder engines. However, its effectiveness is not guaranteed, and its suitability depends on the specific cause and severity of the leak. While it *might* work for some minor leaks in a 4-cylinder engine, it's not a guaranteed fix and shouldn't be considered a long-term solution. If you have a significant leak or a more serious engine problem, Steel Seal is unlikely to be effective and could even worsen the situation. A proper diagnosis and repair by a mechanic are always recommended.
