[Ripcell]

at the thread title says, what oil do people run in their ls1? ive run gtx2 10-30, gtx3 10-30, magnatec 15-40 and gtx2 20-50 and nothing seems to makt the lifters any quieter, does anyone have any recommendations?

We use Mobil 1 in all LS1's at work and we dont have any problems with it. However, every LS1 we service has some sort of noise to begin with. I havn't heard a completely quiet LS1 yet....

yeah i know they are already noisey be it piston slap or valve train but mine seems to be noisier than usual i reckon
