Hello, I have a 2013 prius c. It has an oil leak around the gasket near the timing chain and to get it fixed is almost as much as the car. Instead of using 0w-20, I was thinking of switching to 0w-30 to minimize, if not stop the oil leak. The immediate downside is decreased fuel economy and more wear during cold starts. I live in alabama so the later is a non-issue. GM went to a heavier oil to minimize oil leaks. Thoughts or ideas?
