I've seen VW's, Volvos that call out for specific oil for their cars. Is it really necessary if you change your oil regularly and use a good synthetic brand? I know most people will just get the called out oil b/c it is not much more...
I've read the manufacturers want those oils to extend out their change intervals.
Just want keep using my Kirkland Synthetic!

I don't like paying for things i don't need.
