Message	Hi guys, preparing to run my engine in after a hone using 180 grit ball hone. My previous engine destroyed the bearings very very quickly for some reason, i had 30 weight running in oil in it. Would i be better using the 40 weight running in oil? only going to run it upto temp for 20 mins and go round the block once engine braking a lot before swapping it out to fully synthetic.
