Consider using an
oil to "fog" the engine like they do for boats, instead of WD40. I am not sure what they use, but a marine dealer should know or have it on his shelf.
I think changing the
oil in the spring is better, since this will get any possible water from condensation out of the engine.
I keep mine in the semi heated garage, in a sealed bag from Calif. Car Cover Co. Drive it on, put the normal cover on, then pull the top of the bag over the Cobra and zip it up. Bag is treated to reduce corrision and the treatment in the bag should last for five years.
