Don't leave that in for too long Dave being that it is mineral based - regardless of what they say on the bottle/website.
It was crap in my wife's Magna after 6,000kms (engine became noticeably rattlier the longer it was in there) and only 3.8L came out (5L went in) when it was dumped after 8,000kms.
It will probably be okay for 5,000kms, but don't push it further than that.
