As long as the viscosity is 20, then the MPG will see the greatest benefit. 0W or 5W will only influence cold starting, so if the region one lives in doesn't have low extremes like most of Canada (except Vancouver) or the northern regions of the US (except the Northwest), then 5W oil should work just fine. I'm making this point because 0W oil is a lot harder to find than 5W, unless you want to pay Toyota's silly prices.

The xW lettering in oil is the base oil weight, while the last 2 numbers is the weight at operating temperatures when the viscosity index improver kicks in.
0W-20 is now hitting the mainstream just now - the only place to get it a few years ago was at a Honda dealer since it was used in the Insight and Civic Hybrid. Mobil and Pennzoil have their versions - while Honda has Idemitsu bottle their stuff.

The Society of Automotive Engineers, usually abbreviated as SAE, has established a numerical code system for grading motor oils according to their kinematic viscosity. SAE viscosity gradings include the following: 0, 5, 10, 15, 20, 25, 30, 40, 50 or 60. Some of the numbers can be suffixed with the letter W, designating their "winter" or cold-start viscosity, at lower temperature.
Viscosity is graded by measuring the time it takes for a standard amount of oil to flow through a standard orifice, at standard temperature. The longer it takes, the higher the viscosity, and thus higher SAE code.
Note that the SAE operate a separate viscosity rating system for transmission oils which should not be confused with engine oil viscosity. The higher numbers of a transmission oil (eg 75W-140) do not mean that it is necessarily higher viscosity than an engine oil.

Now, 0W-20 is readily available in BULK at the dealerships - primarily through Nippon Oil (supplier of 0W-20 to Toyota).

i am changing my cars oil sense i boought it, heck i did the 5k service by my self
i use Castrol Edge 5w-40. u know GCC isn't a cold place.
i change the filter every time it cost less than $10.
i remove the engine silver gover and whip the dust, i also remove the air filters and clean them.
i noticed with castrol oil
even after 20k the oil still looks in a very good condition, also the viscosity is hardly changed. but i am gonna change it next week.
no problems untill now
i reached 70k with it.
still smooth as ever but not speedy as my 2005 E55 which i often use it in the city.

yea.. if you look @ the cap it says 0w-20 or 5w-20..
i figure if it snows where you live 0w-20 is the way to go..
but I live in SoCal where it's pretty "warm" temperature year around, so i went with 5w-20..
also.. UPDATE: that smoother sounding thing was all in my head.. ha

Now, the oil cap for the 2010 RX-350 only says "0W-20."
Same for the 2010 Toyota Camry: the oil cap only says "0W-20."
Looks like all the 2010 model Toyota/Lexus/Scion(s) are going to 0W-20.

The lex sits all week so the oil is drained when I do start it. I started with Mobil 1 5w 20w then I had the Lexus dealer put in the Toyota Red bottle Syn I think is 0w- and the car made more noise on starting than with Mobil 1. Now it has Mobil 1 5w 20w and this is what it is getting from now on....FYI

Also, The price of a 0W-20 oil change should go down as more dealerships start carrying 0W-20 in BULK instead of quart bottles.

It was my understanding that Nippon Oil made the 0W-20 factory fill to Toyota.
I believe Nippon Oil also makes the 0W-20 Toyota Genuine Oil (red quart bottles).
