What do you guys think, I will probably either run chevron supreme with 3 oz of rx or mobil 1 no auto rx and do full treatment every 20 thousand miles. Other thought is walmart group 3, not sure yet though.

I think that he just means that you should use dino and forget extended OCI that usually occurs with synths IF the engine is proven to be sludge prone. Unless you're in a really cold climate ..it would be a waste of money to use them for an engine that requires a 3k/3month OCI because of a design flaw.

Here is what I will probably do. Put in mobil 1, change 4000 miles and auto rx every 30k. I know this is early to change mobil 1 but this particular engine runs hot and is known for problems. I would do this over good dyno with maintance dose of auto rx every 3k. Sound good?
