Find me one single european car that specs the **** and i'll change my tune. There are no tighter tolerances, the VCT can run on 5w30, 10w30, 5w40, 5w50.

I believe Ford will gladly reduce your motors life by 30% to meet government fuel economy standards. So your motor might only last 210,000 miles vs. 300,000, this is not a big deal to Ford

i've been using 5w30 or 10w30 for 8 years. I wouldn't buy any supercharged 3v running 5w20. Even roush and saleen don't recommend it in their cars, because, IMO, it is barely adequate for a naturally aspirated 3v.
