Wheels 370z Posted October 17, 2017 Share Posted October 17, 2017 Hi, I understand the science behind the octane ratings/compression for the fuel types and understand the manual does point drivers toward super unleaded higher octane fuel however what's the general opinion? Do the majority go 'Un' or Super'?? Quote Link to comment Share on other sites More sharing options...
Ekona Posted October 17, 2017 Share Posted October 17, 2017 You can run either on a 370Z due to the engine having a decent knock sensor, but unless you've bought the car for four pound and ha'penny then there's no point being a tight arse and losing power and mpg by going 95.

Jay84 Posted October 17, 2017 Share Posted October 17, 2017 Not sure what the price difference is as my daily is a dirty D, but when I had a T sport I worked out that it'd take 100litres for it to even be £5 more expensive per tank. But it seemed to last longer than standard. I only run my Zed on super/higher octane fuel. In terms of majority I'm fairly sure we all go super where we can, some can't get super (Ireland i think) so use octane boosters. Quote Link to comment Share on other sites More sharing options...
zumpitu Posted October 17, 2017 Share Posted October 17, 2017 On the Owner Manual on my Nismo say that I have to go with the 98 ... and say that I aco use for a very short time the "91" ( ? ) .. I'm also a bit worried because I'm going to Italy and is not always possible to find the 98 or is extremely expensive ( for no reason clearly ... is Italy ) Quote Link to comment Share on other sites More sharing options...
