Thanks JAG, I stand corrected. There is an interesting comment in the slides
Quote:
No data has been shown to support the need for increased
HTHS viscosity.
– Higher HTHS viscosity will adversely impact fuel economy
I've done a bit of reading and thus far the need for high HTHS is mixed in the research. The consensus is that it's a very good indicator for fuel economy, but different studies come to different conclusions about wear.
