Title: Mixing Oil.
Post by: scotsjohn on August 05, 2010, 10:28:15 PM
I'm always finding I've got a few litres of different grade oils on the shelves and wonder what's the end result of mixing them. IE what do you get if you mix a 0-40 and a 10-40. Do you end up with a 5-40 or do they separate out pretty quickly?
