 I've used it for many years until I heard of this. I now use 15w-40 Delo in my Chevy V-8's in those instances when I used the 10w-40. Even though it doesn't seem like a big difference (40-10=30 vs. 40-15=25), apparently it is. I also use the 15w-40 in my last (Dec.) Alfa fill of the year and leave it in until the real hot weather (July).
