After sitting for 28 yrs, I put marvel mystery oil in the gas and oil to help clean the engine. Now I need to change the oil. What type of oil should I use?
 
I would go with a 10w30 with a high zinc count, Seems Shell Rotella is one brand. Ask this in the Early V8 section under general discussion.
