It's a powerpoint preso, that I found after the mention of the "Honda Hot Tube" test in another thread.
Has some interesting points.
HTO-06, they prefer, as it doesn't "penalise" high Mo oils...the Japanese OEMs lobbied to get the TEOST range extended for the 0W20 grade only.
HTO-06 has the aforementioned hot tube test, plus a soot/sludge simulation...plus a simulated crankcase with NOx bubbled through heated oil (sounds like my commentary about varnish being formed in the crankcase, with blowby gasses).
Mentions that they are planning their fleet to use "generic" API specs, bar HTO-06 for their turbo models...bear in mid that they DO lobby API for changes in the generic specs, i.e. TEOST in 0W20.
Mentions backspeccing, and the reasons for it (fuel consumption and CO2 depending on market)
I know that HTO-06 isn't going to be applied to any of the grades I'm likely to use, but if/when I get an engine that specs ILSAC grades, it and Dexos will be on my shopping list.
