Would 10W 30 Oil Hurt the Engine - ZR-1 Net Registry Forums

I am about to change the oil my my 94 with 30K miles on it. I have always put the reccomended 5w 30 in but am thinking about using 10w 30 this time. It is a little thicker and it seems like it would give a little better protection. I don't think it would hurt but I thought I would check with anyone who has done it. If there is a reason I shouldn't switch I would like to find out before it is too late.

I would be using mobil 1 with a mobil 1 oil filter. It seems like the mobil 1 filters are as good or better than the GM filters. Thanks
