new (not really) oil from mobil 1, 0w-30 and 0w-20 - Toyota Yaris Forums

I have done some research in the last week regarding oil viscosity, looking at cold flow, cold pumping, and viscosity in centistokes.

i took this information from the manufacturer data sheets, from their websites. German castrol is far too thick, i was surprised at its ratings for being a 0w-30. i was also surprised at the viscositiy ratings for what i thought were run of the mill conventional. Pennzoil YB was pretty good, coming in with low numbers like Penn Plat.

i am currently using castrol edge, because i fell for the marketing, i am going to be changing my oil this weekend (wed/thurs for me) to formula shell synthetic 5w-20. it is by far the lowest viscosity 5w-20 i found. with GC coming in at a 60,000 on cold flow properties at -30c, formula shell synthetic (from its datasheet) comes in at -arround 9400 at -35c. thats all i am concerned with.

im going to give it a try. one thing i did learn after comparing everything, is that marketing plays a huge roll, and that whatever you use, it will be just fine. they are all so close together, it makes almost no difference.
