I run M1 0W40 in my Nytro. Hardly high hp but no issues to report. 4000 kms on the oil last year.

That’s not very impressive at all. Fairly high VI, and therefore VII, evidenced by the shear loss rate of 12%(!), fairly low TBN, fairly high Noack…
M1 0w40 would definitely be above the Schaeffer’s on my list.
You could always see if HPL would ship you the oil you need… you’d just have VAT or whatever else your country has on top of oil & shipping costs.
Sorry I haven’t been on in awhile.
I do love high performance sleds/engines. Though I’m far from an oil expert.
If it were mine, I’d use an easy to get, off the shelf 0w-40, 5w-40, maybe even a 5w-50. But either way, I would make sure it’s fully up to temp, including oil temp, before flogging it hard.
Rowe Hitech synth RS 0w40, Amsoil SS HD and P66 guardol Arctic are all heavyweight 0w40s
I have 2 1200 SD, '09 and a '13. M1 0-40w in both since their first oil changes. The '09 has 10k miles on it now, no issues. Use Doo oil filters.
