What grade oil is always a can of worms lol , but if your cossie pistons don't make a noise when cold (like tappets) then I'd say that their running tight ish clearances ,So I wouldn't jump to many grades of oil at once .

Mabye see how a 10w 40 goes as it will only flow slightly slower, but will only be a grade thicker @ 100°

I do agree with ash as well [emoji106]

as i used millers 10 w 40 running in oil (mineral) and then switched to 10w 50 millers nano drive fully synthetic .

my mahle race spec pistons are only running half the power their set for and are noisy up to 90° oil temp .

But ,just like the wife, they shut up and do their job well when I spank em [emoji39]
