Just wondering, if you were looking at to oils and based on comparing the amounts of Sulphated Ash and TBN number, which is the better to look for?
Eg: Higher TBN and with it the slightly Higher SA
or Lower SA that brings with it a lower TBN
or another way of looking at it is two oils are similar weight, rating and price, but one has say 10.5 TBN and 1.20 SA
the other is 7.5 TBN and .75 SA (lets just say)
What ones is better, and is there going to be much between them?
Thanks!
