The lower a lubricant’s pour point, the better protection it provides in low-temperature service.
Technical specifications for motor oils can generally be found on the particular brand’s
website, although sometimes it may be necessary to contact the company
to ask that they provide them. So, for instance, if the manufacturer said you could
use 10w30 or 10w40 in your vehicle, unless your
application falls under one of the exceptions below, you could safely stick
to an Xw30 oil (using the lowest “Y” value listed) and you could go with
a 0w30 or 5w30 oil safely, even though the manufacturer listed only 10w options.
