a link, table on various grading indexes and compares them @ 40 & 100 deg C.

toyo oils available.
08816-03001 = 3000cst.
08816-06001= 6000cst.
08816-10000= 10 000cst.
web search, apparently 3000cst is used in cooler environments.
and from what I've found the consensuses is to drain, clean & replace with fresh stuff, as the oil will lose it cst rating with use.

cant bring myself to type that word toyo@#, like swearing isn't it !
