Synthetic question!

[ex101]

I've been running that new 4 stroke synthetic oil by Mobil One in my 400 ex/stock bore,and plan on 416 setup soon.Can I safely go back to GN4 for break-in and back to Mobil.I have heard you should'nt go back to conventional oil once you change to Synth.Thanks for any replies!:confused:

its ok to switch oils. just dont use full sythentic during break in. even when u get new cams and piston
