Subaru chose to recommended 5W30 to satisfy the Corporate Average Fuel Economy (CAFE) EPA rule enacted by congress in the 70's. The STi just misses paying the gas guzzler tax at the EPA rating of 23 highway. A vehicle must obtain 22.5 MPG to avoid it. If the STi was tested at 21.5 - 22.4 MPG highway, a $1000 tax would be added to the car appearing on the sticker making it a reality Subaru wouldn't sell it in the U.S..
