Thinking about ordering a bottle of LC for my Cherokee. Have a couple questions...
4.0 engine has nearly 200k on it. It's designed for 87 octane, but pings slightly on it under heavy load. Should I try putting some LC into each cylinder through the spark plug hole?
Also, power steering and transmission fluid are rather dirty even after being flushed. Both currently work perfectly. Is there *ANY* chance that adding LC to either of these could cause bad things to happen? I don't know much about how those two things work...
