So, do what you want and reap your just reward. I've owned over 70 cars in my life and don't expect to have this one for more than 40K miles. I'm am looking for the highest performance that pleases ME; so to each their own, take my advice or trash it; just trying to save some owners some heartache. Ioften run my car at 80-100MPH on my 32mile everyday commute and need the engine to run and live at the upper torque peak. The Toyota Manual strongly suggests running higher viscosity oil than the supplied 5W-30 at high speeds for extended periods - so YOU suggest we do the OPPOSITE that the Toyta Engineering recommends? Oh, now THAT makes sense ( cough) I'm just running the weight that came in the car - even THATS supposed to be too thin for my scenario. But Of course , Sz, EVERYTHING is perfect in Toyota land, so just piss in your engine and put on a Fram filter and you're good for 200K miles.
p.s.:
If any one want some REAL info about oil - go to the Tribologist's professional site at NORIA and poke around. BITOG is full of baffoons ...

Grumpy, where are you getting this so-called "Toyota Engineering" boolsheet?
A bullitin directly from Toyota says we can run 5W-20 and 0W-20 in our Yaris engines WITHOUT ANY PROBLEMS. This is from Toyota! It is official. It is a TSB that one can find here and many other Yaris sites. And you claim that 30w is too light? Why should anyone believe you over Toyota?
Please do post any and all "official" Toyota information specifically for the Yaris that says otherwise. If you can't then you need to be man enough to admit that you have a problem with spreading boolsheet on the web.
