OK, all this as I was on 10%. I was trying different mix this summer, to see what was the best, form 0% , to 5%, to 8% then 10%.
Now I am back on 15%, it seems to be what the car like.
10 degres ish last nigh, the engine fired up in 2.78 seconds, a wee longer then dino but no hiccups and all on 6.
I'll stick to 15% now.

I like to know about this oil though. Is it available in the UK?
Cheers.
