I'll replace the Goodyear F1's with a set of Continental DWS all season tires when they get wore down. I'm on my second set of DWS tires on my Mustang and I'm very happy with them outside of getting more then 2-3 inches of snow on the ground...then I'll take my girls Escape to work if I need to :)
I should be taking delivery of my SHO next week, but I was curious as to (if there was any) long term issues with running regular fuel vs premium fuel with the SHO engine? I know that regular fuel gives up about 10HP vs premium in the car, but I was more concerned if it affected driveability etc...
One thing to keep in mind is you might be having a issue with the capless fuel system on the car. I know my fiancée's Escape check engine light was coming on and reporting bad O2 sensors. I replaced them and still had the same problem. I come to find out that the valve failed in the Capless...
