Thanks Joe.
This crate is a carbureted 350 with a mild cam and 330 horses.
First crank was April 2012. Mileage is 1604 averaging about 60 miles a month. It's been over two years with the original oil. I just wonder if it should be changed even tho the mileage is so low. Also, do you have a recommendation on what additive would be best to use?
