I know it's needed for a flat tappet break-in, but is there any benefit using EOS for a roller motor break-in? This is for a ZZ4. I read in the GMPP catalog that it should be used during break-in with all of their new cams regardless of tappet design. But the break-in procedure for my motor doesn't mention it. It says to just use 10w30 conventional. any thoughts? Thanks.

 

any added lubricity during break in of any style tappet is well worth the little bit of money that the eos costs...

EOS engine oil suplement puts back into your oil componants that have been removed over the years by the smog *****... most importantly is zinc... 95% of all multigrade oils have had all but the slighest amounts of zinc removed from the oil...

an ounce of prevention is worth a pound of cure... put it in run it...
