rofl black and gold oil, what was ur mate thinking lolz.
I use Penrite Sin 25 in my VL. Bloody hard to get around here though.
I go with what is recommanded dude, 20 50w for sure its a 6!!... keep that and never change it again...the more money u spend on oil the better it will be for ur car..
a tool i knew used black and gold brand oil in his v8 vl, that didnt last long at all car went bang!!
what does that have to do with what grade oil it takes ?? just because its a 6 doesnt mean it takes thicker oil. for example a BA falcon takes magnatec 10w-30 even thinner again
