Mobil 1 0W-30
Has anyone switched to this Mobil 1 0W-30 product? Apparently it is suppose to be more fuel efficient and better for those vehicles that already use 5W-30. It is a little more expensive, but that comes with the "advanced" anything label. I was just wondering if it is worth switching from what Lexus and its factories only require that our vehicles use the 5W-30 oil.

I know a friend of mine that uses that oil. he is a BMW tho.. he says its pretty good. but nvr heard anything on lexus engines... 
i doubt that going lower weight should effect anything to the car. i once used 5-40 for 5k miles that didnt feel any different either. i just had to wait a bit for my car to heat up a bit.

The W doesn't stand for winter. In 1911 it did mean suitable for winter use, but now it means a different testing standard has been met by the oil. It's a common misconception.

From SAE J300 p.2:
"Two series of viscosity grades are defined in Table (1): (a) those containing the letter W and (b) those without. Single viscosity grade oils with the letter W are defined by maximum low temperature cranking and pumping viscosities and a minimum kinematic viscosity at 100C. Single grade oils without the letter W are based on a set of minimum and maximum kinematic viscosities at 100C and a minimum high shear rate viscosity at 150C. The shear rate will depend on the test method. Multigrade grade oils are defined by both of these criteria....
The W is just a designation of one type of testing vs another.
