Shoving 0W20 down our throats to reduce C02 by millions of tonnes (its
a British story) seems to be the future.

Note that even 5W30 specs are more like 5W25 in actual grade, if there
were such a thing. Also interesting that this story proclaims oil
increases in viscosity with use. B.S., the modifiers break down and
the oil reverts to its true state, which is thin, not thick.

This story is a tree hugger event.

Still sticking with 10W30.
