All of which has nothing to do with the 0W rating. Why are we going on about this in a thread about the cold cranking specification?

NOLN: What type of fuel efficiency increase are you seeing with 0W-16 oil?
Miyamoto: So we tested a Honda Fit on a dynamometer. The 0W-16 showed an improvement in fuel economy by 2 percent when compared to 0W-20.
Takahashi: Two percent doesn’t sound like much just car by car, but when you look at the overall carbon footprint one company can make by saving 2 percent, it is quite substantial — especially when car companies like Toyota are selling millions of cars a year. Saving 2 percent on half of that fleet really makes a difference environmentally.
NOLN: What are some of the concerns about 0W-16 oils?
Miyamoto: [Some may be worried that] lowering viscosity might cause increased wear or a pressure issue.
Takahashi: Those were concerns with having such a low viscosity oil, but with more than 15 years of background in 0W-16 oil, we are able to address those issues and create a benefit of increasing fuel efficiency, when compared to 0W-20 oil.
NOLN: Can you share some information about what you’ve been doing with 0W-16 oils in Japan?
Miyamoto: 0W-16 oil was introduced in Japan before 2000. 0W-16 showed higher fuel economy than 0W-20 engine oil. It will also give you remarkable quick engine starts at cold temperatures. There are several concerns [about 0W-16 oils] due to their lower viscosity, like increased wear, increased oil consumption and lower oil pressure. But our long history [with 0W-16] has addressed these concerns. The 0W- 16 project is just the beginning of what JXTG Nippon Oil is striving to do to offset carbon footprints. Actually, we are currently working on an 0W-8 oil.
Takahashi: We are taking our knowledge and what we have already been doing in the past in Japan and trying to expand it here in the States. There are products like the 0W-8 oil that we have already been working on — it’s been a couple of years since we started filling some cars with it back in Japan. We don’t know as of yet when it will be coming to the U.S. market, but there will be a target point for that in the future. We have been doing 0W-16 oil since the late 1990s, and it’s finally coming out here in the U.S. market.
