I just received the Blackstone report on oil analysis for my 2006 Focus. The vehicle is not modified in any way and runs about half city and half highway driving. I sent the oil in for analysis at about 8300 miles. Now Amsoil says this is their 25k or 15k severe service oil. I am also using a Baldwin filter.
Needless to say that I am disappointed that this high end oil is recommended to be changed at 8k because of the elevated metals in the oil. I guess I will be calling Amsoil tech services in the morning. I should note that I switched from Amsoil 0W20 in my Honda Odyssey when I started to notice the beginning of sludging. Now running PU.
