Thanks very much. Mannol atf it is then.
Out of interest, do you know the mixing ratio of the volvo coolant? Manual says I need 9l of coolant (mixed). I can find 4l bottles of concentrated but can't find the mixing ratio anywhere. I'm going to hazard a guess and say it's 50/50, just to make sure I need an extra bottle
Edit: cheers Blue Rubber, you answered my question while I was typing.
