Oil change due on my sister's Mini. Local supplier recently started stocking Total Ineo Dynamics 0w20, LL-17FE+

That is high but not abnormally so.. the question is what compromises(if any) were included to get it that high.

There's a few 0W-20s in that park...


If it's the truth....it can handle the pressure !!!

highest I have seen.....not that I have actively searched...but seems a lot higher than the ones I have seen....What are the other ones over 200?

This is actually an interesting oil.

ACEA C5 oils tend to be low-VI oils, as opposed to Japanese-OEM oils, which tend to be ultra-high-VI oils, as wear protection (thick base oil) is the priority for the former and fuel economy (lower viscosity in a wider range of temperature and a wider range of temporary shear) for the latter.

Therefore, I ran my calculator to have an idea of what is going on.

>> Estimated base-oil viscosity @ 150 °C (BO DV150) and VII content of selected oils <<

It went nicely right above the TGMO 0W-20. wink

It turns out that this oil actually has only a moderate amount of VII content, and the ultra-high viscosity index (VI) is thanks to the very high VI of the base oil, which must be a Group III+ or Group III++ etc. base oil, as the MSDS shows an almost entirely Group III(+ etc.) base oil. Moreover, the way the definition of the VI works is that for thinner oils the VII increases the VI a lot more than for thicker oils. This is because the VII typically multiplies the KV40 and KV100 approximately by the same number. As a result you need less VII to make a 0W-20 with VI = 220 than, say a 5W-30 or less VII to make a 0W-20 than a 5W-30 of the same VI in general. This is another strength of thinner oils.

The base oil is still on the thin side for a 0W-20, but not as thin as what would be expected from the ultra-high VI.

It may probably use a small amount of ester as well, as they mention polar molecules for cleaning.

Well, here is one with a VI of 244 (238 in spec sheet)

Mazda 0W20>

It is a Total oil, branded Mazda original. 900ppm of moly too.

I like the bottom right: More languages, open here... There aren't enough on the label already?

VI is a good measure and it's pretty high in Total. But what's more important I think is how viscosity changes relative to temperature range which has big influence on oil viscosity.
For example Castrol Edge 0W-20 has lower VI (172) then Total, but @40C (43.6) and @100C (8.4) is higher on both counts.
