A question about Mobil 1 0w40 or others 0w40 grade oil and Shell Helix Ultra 5w40.
I just read the Shell feature and notice that Shell is an atypical 5w40, in fact this oil has characteristics typical of an any 0w40.
For exaple, this is Mobil 1 parameters:
V100° : 13.5.
v40°: 75.
VI: 185.
flash point 220°C
HTHS Viscosity, mPa•s @ 150ºC, (ASTM D4683) 3.8
Ok, similiar to others 0w40 on the market.
We now take Shell Helix Ultra 5w40:
100°C: 13.1
40°C: 74.4
flash point 215°C
HTHS Viscosity, mPa•s @ 150ºC, (ASTM D4683) 3.68
Shell Helix Ultra 5w40 appears to me very similiar at any 0w40 grade oil, and it does not seem to be a typical 5W40.
Now, i think that getting a 5W40 oil with the parameters of a 0W40 may provide some advantage for those who want a 0W40, cause the 5w40 oil should be more stable having a lower range of gradation.
Basically I have an oil (Shell) with the characteristics of thinness of a 0W40 but with a less "extreme" gradation range (5w40).
This argument could be right?
Best regards.
