I have just purchased the Japanese 2006 Skyline 350GT and couldn't find a definitive answer. Supposedly our best fuel is BP 98 however many seem to choose 95 over here in New Zealand. The price difference is 95 = $2.29/l and 98= $2.56/l. I'm assuming any benefits of 98 are outweighed on a price standpoint and that it won't do any harm, would that be correct? (Should be the same as a G35).

Cheers
