Thank you Zend, molakule and supercity

The Q8's operating viscosity would drop to 20 mm²/s at about 60*C, above which you may loose gear pump longevity protection.
Considering the upper side over 60°C, the values for both a Q8 Artctic, HVLP46 or 5w30 UTTO are quite the same, around 20 cst. So there will be no change choosing any of them.
The only difference is on the down size, and only the Q8 performs well here.
I have really no idea of the oil temperature that will be reached in summer during work, so I don't know if there will be a problem here...
Anyway, I have a spare pump, only 80$ in China...

I would feel the Q8 is not suitable for the powershift transmission.
