15w-40 by the looks of it.

Dunno, does it go below -15c much where you live?

 

[McBunny]

does it often go below -15 anywhere in the uk !! that will be a no then lol

 

[Fred@BTM]

0W, 5W, 10W etc refers to the oils viscosity when cold 0degC IIRC

40 is its viscosity at 100degC

something along those lines

lol so basically the oil has to be 40 but the bit before the w aslong as its 15 or below its ok ?

Yes the 15W (winter) is the lowest grade your car will take.

But, for better engine protection, use 0W or 5W.

SAE 40 is fine for most cars, some fords,nissans,VWs use SAE 30 for longer engine life, dont use that grade unless it says.

Find posts by oilman, all is explained in much more detail.
