I would like some feedback on the best choice for a summer diesel additive. I have been using Diesel Serv. injector cleaner which seems to work. I am concerned about keeping the fuel pump properly lubricated. I am using it in a Case 580C. It runs well and does not burn oil or smoke excessively. I am somewhat of a greenhorn to working on diesels, so be gentle.
