German Castrol 0W-30
I've searched the forum and found that some of you guys are running German Castrol on your Toyotas. How is it holding up with your Toyota? I know many people with European cars are running GC, but I would like to know if it works well with Toyota vehicles. How is gas mileage? What mileage do you have on your car with GC? Any side effects? My 3.4L V6 calls for 5w-30, and I am currently running mobil 1.
