Here is the most definitive discussion of oil I have read. Check it out |
I've read that article several times in past. And, based on what I can glean from it, the lower the viscosity rating is on start-up the better it is for initial lubrication (i.e. 0 vs. 5 or 10). Thus my decision to use a synthetic that has a rating of 0-40w . Does this make sense ?
