do a quick search for 'oilman' in the author section of the search engine... he has a few posts on here that are very interesting

i think the viscosity is the oils ability to flow, say a litre through a hole the size of a 5p, a 5w oil will flow faster than a 90w. think they get the rating, the time it takes to flow through a hole. say 10w 40, i think the 10w is the thinnest it can get but when cold, say in the winter, it will be 40w until it warms up. iam not saying this is correct but thats what ive allways been told.
