Viscosity of Castrol Magnatec 5W30

[Diego3336]

I am currently using VML 5W30 syn blend on my Zetec engine but I am thinking to try a 5W30 on a thicker side of the 30 weight, and as the Magnatec A5 5W30 is almost the same price of the VML here now, I think I will give it a try, as the Magnatec 5W30 here in Brazil is full synthetic and was the OEM Ford/Motorcraft oil here until a few months ago.

The thing is, I can't find the "spec sheets" of Castrol oils. Are these specs buried anywhere in the global Castrol website?

Thanks

Possibly this is the one?

Looks to be on the lower end of the 30-grade.

Thanks, Quattro Pete

Too bad this Magnatec is even thinner than the VML I'm using now. According to the sheets, the viscosity @ 100ºC is 9.8 cSt for the Castrol versus 10.7 for the VML.

I think I will try the Shell Helix HX8 5W30 on this engine instead. It is 11.93 cSt @ 100ºC and I already have 4 liters here that I bought to the Fiesta a few weeks ago and didn't changed yet.
