I have always used Aeroshell with great results. But , lately I have been hearing things from customers that perform oil analysis routinely that the "new" Aeroshell formulation causes higher copper results in their oil analysis. I had one tell me that once he changed over to Phillips that the next 2 oil analysis results both showed copper back to normal . Has anyone had any info on Shell changing the formulation? Thanks, Walt ________________________________ Message 2 _____________________________________ Time: 07:57:26 AM PST US From: "Rick" Subject: RE: Engines-List: Aeroshell 100 Symptoms can be problematic. He might want to change back once more to see if copper goes up again. Then switch if necessary. I doubt either oil would cause abnormal wear. If it is an experimental engine you can run what you want. Keep in mind unless you have an engine modified for unleaded you must run at least a semi-synthetic if you go in that direction.

They used to use TCP, but it is now TPP. As I understand it, there is not a problem with straight Aeroshell (not Plus) and not with Exxon or Phillips. I don't know if there is any concern with the higher copper numbers. You might email Blackstone for their opinion, and then write Shell and see if they have a comment.
