Engine Rust During Storage

[gregdacat]

Has anyone ever had a problem with rust on your internal engine parts when you store or drive your Boxster very little in the Winter? I have a friend that has a couple of cars he drag races and he said if he does not idle his cars a couple of times a week the internal springs and other small iron/steel parts start to rust. He runs Royal Purple 0w-20 oil and that may be part of the problem. (too thin)

All I know is I have not driven my car in 3 weeks and the rotors look horrible (rust)

Thanks
