Have no idea, but it does include me. Last I checked though, 10W30 was still the best selling grade.

Agreement has been reached on GF-5.

Per my own observations, it's a very significant impact. Going from a 10w30 to a 5W-20 caused significant fuel economy gains while the engine is cold.



....that's why I use up the 10w30 in my stash during the summer.

no mention of HTHS in the draft spec?

SAE J300 defines HTHS. It's #1.a on the spec.
