arco, where did you find that data sheet, the only one i could find was the one i linked and i dont see 40c on it? can you post a link?
 
based on arcos numbers here is the data

at 15F
Mobil 1 10w30 =1332cSt
Mobil 1 High Mileage 10w30 =1855cSt

@ -4F
Mobil 1 10w30 =3422cSt
Mobil 1 High Mileage 10w30 =4890cSt

GC
at 15F
GC 0w30 =1025cSt

@ -4F
GC 0w30 =2313cSt

You couldn't have - they don't sell Mobil 1 High Mileage oils in Canada!

Unless you picked it up in the states........

I have the pdf saved in my oil doc archives. If you PM me your email address I can shoot it to you :)
 
CCS and/or MRV numbers, they are measured differently in cP not cSt. Take note of the temps measured as differing winter grades are measured at different temps -25/-30/-35

GC0w30= 12.1cSt at 100degC /66.8 at 40degC datasheet 4/15/2008
Sorry, I fed jstutz incorrect data the 66.8 number is the 210F SUS viscosity. This will throw the viscosity curve extrapolation off. Wish BP would follow EVERONE ELSES convention on data presentation and include 40C cSt. Maybe they got something to hide?

If they are certified to SAE J300 5w appellation then they are all good for that winter service category. There is no good and bad. Its all pretty simple, If you are seeing sub zero starts over an extended period, select a 0w/5w-XX oil, if not run 10w or specified monograde. No need to overthink because it does not make a huge difference in wear or fuel mileage as other factors tend to overwhelm.

If they are certified to SAE J300 5w appellation (6600cP@-30c MAX) then they are all good for that winter service category. There is no good and bad. Its all pretty simple, If you are seeing sub zero starts over an extended period, select a 0w/5w-XX oil, if not run 10w or specified monograde. No need to overthink because it does not make a huge difference in wear or fuel mileage as other factors tend to overwhelm. If you are seeing -40C/F starts then you may want to think harder about w categories (and a block and pan heater)

Amen to that!
