have any of you actually hooked up a manual oil pressure gauge to the block to read during various loads and RPM speeds against one oil vs the other.
simple..... BOTH oils are rated to flow "like" a 5 during cold. its the operating temperature flow rating that changes. if the places the oil has to flow are tighter and/or more narrow passages then the 20 would be able to do that better, resulting it better protection. slightly thicker oil would technically mean more protection against thinning out under heat but is really the shearing forces more people should be concerned about instead of the flow ratings which is all viscosity ratings are really intended for. more people should be concerned with the other specs that manufacturers list on their websites and not necessarily on their products bottles. main difference people notice... fuel economy UP on the lower viscosity oil due to less effort for the oil pump to move around the fluid, and guess what drives the oil pump |

I hear more about increased engine noise, and less about increased fuel economy...and with the info that's being passed around here about the possible oil leak at the head gasket I'll stick with the recommended thicker oil.

How would this fare in all this discussion, I am here in the desert environment hard driving, usual runs are 100kmh-120/140kmh on say 60-70kms a day and it may still be cool now 14-20C but it could shoot up to 35-40C in just a couple of weeks more.

Just got e-mail from Toyota executive office in California saying that 5w-20 will be allowed for the Yaris . Sent them the T.S.B. EG018-06 and has been confirmed . Now have approval from the service center where the '08 sedan was purchased and the executive office . Will come in play if any warranty issues should occur when using the 5w-20 . May stick with the 5w-20 at all times . If so , will post an used oil analysis after a few runs of it . That will probably be later in the year ( December ) .

Just for laughs, I recently looked up on Pennzoil's website what the recommended oil for my 07 Yaris is. They say 5W20. Then I looked it up on Kendall's and they also say 5w20.

My first post will be bring back this old thread. I just changed to Mobil1 10/30 wt. and my 08 is running smoother and has less clatter when cold. It had Toyota 5/30 wt.
I've never bought into the whole water like oil fad. I feel the auto makers are sacrificing our engines for a little bit better mpg. They are clearly under the C.A.R.B. Gun. JFYI. |
