hi simon, the info i posted i obtained from volvo north america tech support dept who were very helpfull in contrast to volvo uk(take it to your dealer blah blah)the volvo oil is in fact a perfectly normal standard full sythentic 5-30 which is supplied to volvo at present by texaco, repackaged and flogged on to us mugs at a vastly inflated price! i have used valoline 5-40 synpower now for many thousands of miles with no problems as 5-30 is more difficult to obtain however its a case of yer pays yer money and take yer choice! however your gearbox willl thank you as its a third of the price volvo ask you can afford to change it three times as often!
