I wouldn't worry about any corrosion, Steve. As luck would have it, absent significant engine failures, the
oil is inside the engine and once the engine has been started the entire interior is coated with an
oil finish. Moreover, unless you disassemble and wash the engine parts it is essentially unheard of for the oil finished components inside the engine to rust over a winter — even if the vehicle were left exposed to the elements outdoors.

I have no idea what oil is in it, pulling the stick the oil is a light amber. The engine has less than 1500 miles on it. The car also has two side by side Fram Racing filters in it. I have read quite a bit on oils and still would like someone's opinion.
Thanks,

The best thing to do is to ask the builder who built your engine what oil
he wants you to use. He is the only one who knows, with certainty, how your engine was assembled and therefore what it will require.
