Can we upgrade our engine oil to 20w-50??

Hi all,

I am having a question about upgrading enigne oil grade. In my alfa, though the recommened grade is 10w-40 on a stock one, we all use 20w-50. There are couple of reasons for this,

Alfa engines are known to drain out oil (Like for every 2000 miles we have to add 1 quart of oil to keep the level).
The engines run relatively hot ocmpared to any other engines, my engine runs at 194degF at normal freeway driving conditions (which is considered to be normal) and sometimes on hot days it even goes to 212 (which is also common).

So, can we also change our grade to 20w-50 in my svx, so that I can use same grade oil in both cars (not that our temperatures go tht high, but based upon the age of the engine)???

thanks,
