I recently purchased an E-M 2005 built cobra with a 351W engine built by a custom shop out of state. It's winter here in upstate New York and I'd like to change the
oil to eliminate any potential corrosion while it sits for the next 4 months and have it ready for the summer when it finally gets here.
What is the best blend and grade
oil I should use. I only plan to run it in the warm weather so I don't feel I need a dual "w" blend. Also should I use a
synthetic blend, full
synthetic or non
synthetic oil. Can I switch either way on oils without creating a problem? 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,
Steve
