Mobil 1 Synthetic 0W-40 Motor Oil

[90mustangGT]

I was at the autoparts store the other day and noticed it. First time I saw it. What do you all think about it. Real thin on cold starts but stays thick when it gets warm. I run Mobil 1 5W30 Synthetic now with an oil cooler, maby I'll try it.

What do you think???

I saw it as well. I think it's way too thin for our cars. I'll stick with the 5Ws and 10Ws....

Yeah, you need a tight engine for it to work well without buring off by getting by rings and valve stems. I'd run it in a new long block, but not one with many miles or wear.
