Found this in a WRX forum. Anyone have Delvac 1 at their local Sub. dealer?quote:
Mobil 1 5W-40
Using the same technology as Mobil 1 0W-40, MOBIL HAS MADE MOBIL 1 5W-40 EXCLUSIVELY AVAILABLE TO SUBARU DEALERS.
This product fulfils the viscosity requirements of Subaru for use in all of their model range. Mobil 1 5W-40 makes available the same benefits achieved by Mobil 1 without the extreme low temperature capability and ulta quick circulation offered by the 0W rated product. Mobil 1 5W-40 will be available exclusively to Subaru dealers for routine servicing. For interim lubricant top-up, we advise customers to either return to dealer for top-up or use Mobil 1 Motorsport 15W-50 for DIY top-up. While Motorosport is 15W-50m, the viscosity will have negligible effect on the sump viscosity and the lubricants are totally compatible.
