Is there 5W-40 Conventional?

[huffmuds9320]

Since they make 10W-40, 15W-40 conventional, is there such a thing as conventional 5W-40. If so who makes it and where to find it.

Chevron makes Delo 5W40 and it is conventional group III oil!

 

[MNgopher]

Others would also argue that Shell Rotella T syn 5w40 is a conventional oil as it is technically a group III base oil.

 

[Dr. T]

In the U.S., a Group III is a synthetic and even in Europe a Group III is a HC/Semi-synthetic oil.

Can someone tell me when a Group III became known as a Conventional/Mineral oil???

Citgo makes a 5w-40 blend. Here are the specs.
