A conventional low silicate type , (sometimes called "inorganic acid technology") is the specified type for a D1-30 The Volvo product is green. Other manufacturers' products may be other colours. Read the description , dont rely on the colour alone. Diluted Volvo green is still green though

Do not use an advanced/ OAT ( organic acid technology ) / long life antifreeze unless it is already in use in your engine, in which case continue to use the same type. DO NOT mix the two types or chop and change between the two types.

Just to clarify: the D1-30 was originally specified with G48 green but is now, and has for some time, been specified with VCS/VCS2 OAT coolant. Use what is already in the engine, unless you do a very thorough flush in which case you can upgrade G48 for VCS
