WD-40 for cleaning engine?
Is using WD-40 on a nitro RC-car engine a bad or good thing?
My friends will usually at first run the engine completely empty, then spray quite a bit of WD-40 directly into the cab while turning the motor for some time. I have heard a lot of different things about WD-40 -- how some people say you should use it for certain things, while others say the direct opposite, that you shouldn't use it, e.g. to clean a motorcycle chain.
Should I do this to my engine?
And question two:
Does it hurt the engine if it is operated normally, then the engine is killed by blocking the exhaust; then letting the car rest for a few months, with the fuel tank half full?
