Where did you get that info? I tried emailing Castrol Canada for that data and nobody responded.

I'm especially anxious to know the viscosity at 40c for GTX 5w20, so if you have a contact at Castrol who can give me this info, that would be fantastic!

Is there a way to move AndyH's chart to the top of the thread? It appears that Andy will keep updating the chart, so top of the thread is a good location.

Base on those fact, which one is more important? Visc @100degC or HTHS number? Or maybe other point? Thanks for reply..

With these three data points I don't know if it is as simple as which is most important.

In some ways, I wish I had added cold cranking, NOACK Volatility, and Viscosity Index as well. And even then there is far more to picking the right oil.

I think our chart just allows some quick reasearch as to whether a given oil is thinner than, typical of, or thicker than other oils in the same grade.

This might allow us to pick an 'thinner' oil for better mileage, or a 'thicker' oil for more protection in a modified engine or service use application, or to reduce oil consumption slightly.

The HTHS number should also be some help in determining if an oil will be better in a modified engine or service use application. Or, whether an oil might meet or exceed one aspect of a factory approval.

I drive hard, so I still think that a thicker oil at 100 C and a higher HTHS number means improved protection.

If I did lots of cold starts, and drove easy...then I might think that cold cranking was most important.

Other forum members might weigh in with their insights, and reveal what I have overlooked or mistated.

Thanks a lot for your detail explanations. I do really appreciate that. Now I understand what kind of oil I must use in my vehicle.
