By providing your own oli you can use a better oil than the one Nissan uses. I think there has to be an element of trust of them using it. Also ask for the container back after the service as you should get some left in the bottom if you are supplying 5ltr and the oil change requires 4.7ltr. Handy for top ups
It's totally your choice.
give jdmperformance http://www.mjpauto.com/ a call. Both do nissan parts cheaper. Also you could try Holdcroft (Nissan dealer) they do forum discount on parts
We did write a article and supplied some pictures from the wales trip after being asked by magazine with assurance of it being printed. Didn't happen for some reason
£32k in Japan £37k in US. Nissan claim that the price tag of around £55k is justified due to the engineering network required here to support the GT-R and also the additional cost is due to the chassis and engine tweeks required for our roads and climate.
