Actually, that's not so. Mobil 1, 15W-50 is a very robust oil, with a stout additive package containing the ideal levels of ZDDP and calcium. It's also perfectly suited for highly stressed turbocharged engines in hot climates (such as equatorial zones and the middle east) and has excellent HTHS values of 4.5 mPa•s @ 150ºC (302 degrees F) (ASTM D4683) Put another way, it retains excellent viscosity at extremely high temperatures.
It's unfortunate that it costs so much at your location. I can purchase a 5 quart jug (nearly 5 liters) at the local WalMart for $24 or so.
I have a turbocharged Honda S2000, making 407 RWHP, not surprisingly, it does best on M1, 15W-50.
Interesting side note, if you're going to have to run a portable generator for extended periods in a hot climate, (ie post hurricane in FL) this is the oil to put in your generator to keep it from blowing up.
15W-50 isn't the best oil Mobil 1 offers for turbocharger protection as it's made from cheaper base oil, since 15W-xx grades don't require excellent base oils. They only give it three stars. European formulas with better base oils -- 0W-40, 5W-50, and ESP 0W-30 -- get four stars for turbocharger protection. In addition few modern engines require xW-50 if there are any.
