Thanks guys,
I have not been able to take the valve cover of so any feedback I give here is just my opinion. I did notice cleaning on the dip stick when doing ARX and I would definitely feel the filter filling up within 400 miles or so. After I would chance them the car would feel much smoother, much easier to rev.
MMO, I think is a very gentle cleaner, cant comment on it even tho I have used ti for a while. If being replaced with oil, you will have to add oil again later on. The oil definitely get darker.
Kreen, is a cleaner I will probably stick with, simple to use, no harmful effects. I ran it for 2k the first time and the oil was dark, very dark. This will be the last time I go with kreen.
As advised I will go with a dino, run it for say 1500 miles or so and then switch to a high quality synthetic, I am leaning towards Amsoil.
Hope that helps.
