Some dealerships will use 5w30 over 5w20 because generally its cheaper in bulk. I have lubricants training and used to sell lubricants (9 years worth) and now run a performance tuner shop inside a Toyota dealership. I personally run a light viscosity 5w30. .02 mpg is not worth less life out of an engine.
