Oil Cooling Lines and Oil used

[firecadet613]

I use Mobil 1 5w30 and have a lot of problems with my lines leaking.  How about everyone else, if you don't have problems with the leaking oil cooling lines, what kind of oil are you using?

I use Havoline 5W-30.

 

I don't have any problems now, but I did have to replace my lines because they were about to rupture.  But this is common on late 90s-00 or 01 Blazers.  the lines seem to be the problem not the oil.  I used the same oil in my 96 S-10 and had no problems.
