[QUOTE="BigTaco, post: 1815482, member: 61588"] Lots of info here. The “W” stands for winter in multi viscosity oil and not “weight”. The first number represents a cold flow score at -22F. Like golf, the lower the score, the better the performance in the cold. The second number is SAE viscosity at 212F. All motor oil gets thinner as it heats up. Motor oil technology has changed a lot and the base oil used makes all the difference. A high viscosity index can be achieved with viscosity improvers, but it will shear down over a few heat cycles. Oil with a good base to start with will be shear stable and maintain its viscosity through out its life. You hit it on the head with the late 90s CAFE targets. Oil has evolved alot since then thinner grades can maintain good bearing protection in addition to the benefits/efficiency gains. [/QUOTE]
