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.

Acording to oil manufacturers to call an oil SAE (Society of Automotive Engineers) a 30 weight it must be betwwen 9.3 to 12.5 centistokes at 100 celcius. I use an 5w30 thats near 9.3 at 100c. Im making a compromise between what Toyota originally spec's for our engines and what they now say as people want more mileage and they sell more fuel sucking Tundras. A 20 weight on the other hand is any oil between 5.6 to 9.3 centistokes at 100c. why would you take the chance and rely on tha additives to prevent wear like in a 5w20 when in a 5w30 you will rely on hydrodynamic lubrication( the oil itself).

Thanks. Is it Amsoil 5w20 thats 9 centistokes at 100c? if so go for it , its close enough, to what your happy with. The last time a ran Amsoil a few years back, their 5w30 was more like 12 centistokes? I cant remember which one it was! If you live in a warm climate I would go with a heavy weight 5w30. you won't see much milege improvement with only a 1 or 2 centistoke reduction, so go with the cheaper or more readily available one. I live in Canada and its not that hot so I feel safe running a lighter weight. If I lived in Texas for example I would find a 5w30 on the heavier side.
