Oily Nissan Maxima

...

My service centre used 20w-50w oil rather than the recommended 10w-40w grade in my 2004 J31 Nissan Maxima at my last service. Should I have insisted on the recommended grade?

Nissan specialist Jerry Newman tells us that 20w-50w is regarded as a little heavy for a modern multi-valve engine, and that 10w-40w or 15w-40w is preferable depending on the temperature of the area you live in. Either grade would be suitable for your area, but the 10w-40w would be better if you were driving regularly to the snow where it would be much colder.
