Anyone heard of this product? http://www.motrlube.com/home.html Doesn't appear that they make OW-20.

xcel said:The Champion Labs designed Mobil1 with its all-synthetic media will pull down to 5 microns in the same SAE multi-pass.
I'm not sure about motor oils but many gear oils do contain an emulsifying agent to "blend" tramp water with the oil to keep the water from coming into direct contact with the metal that the oil is protecting.Insightful Trekker said:Last time I heard water and oil don't mix.
AZCivic said:WATER! Once the oil has reached it's saturation point and can no longer hold any more water in suspense, it will end up collecting on all the wear surfaces of the engine producing incredibly rapid corrosion. Generally you don't want to go more than 5000 miles between oil changes, or 10,000 at the absolute most if you spend most of your time at light load, low RPM.
