I have just completed an oil change in my truck. The oil was Mobil 1 5w20 with a Mobil 1 extended life filter. I am getting ready to switch over to Amsoil and decided to throw my last bottle of Auto RX into the engine just to clean up anything that is in there before installing the Amsoil with one of their EA oil filters. I am also going to be posting a used oil analysis on the Amsoil after 15,000 miles or 1 years time (should be close to 15,000 miles under a severe service interval). Whichever comes first.
Back to my ? Would it be Ok to leave the Auto RX in the engine for say 7500 miles until I switch over. There should be little to no crud in the engine as there are only 27,000 mile on her. Whatya guys think?
