  1. My point is that I didn't realise I was using the wrong fuel. The cars done 35000km and Im only doing 6000km per year so I don't care if it reduces the total life of the engine as I'll be selling her before 50,000km. I just wanted to know if any issues or consequences are going to show up in the short- medium term, and based on my own experiences over 3 years, I will say probably not!
  2. Thank you for your replies, but some of you are missing the point. The book says use 96+, so obviously 98 is ideal, but I have been using 91 for over 3 years with no loss of performance or economy or signs of issues with the engine. She has also been serviced by my local Nissan dealer. Essentially I want to confirm that if my use of 91 was going to cause any problems then it would have shown up by now. Is this correct? Thanks
  3. Hi guys I've seen a couple of threads on this subject but none that answered my specific question. I've had my 2009 370GT (7 speed auto) sedan for over 3 years and 20,000km now and ever since I bought her I've only ever used 91 petrol (the same as I did for my V35 300GT) because I never did any investigating. I have never had any problems running on 91 - she runs smoothly and perfectly, does 0-100 in 5.5 sec, no pinging, rough running etc, and I can consistently get over 600km on a tank with a motorway, city, cruisy and wheel spinning mix of driving. It was only researching about doing an oil change myself (and downloading a US Infiniti G37 manual) that I came upon the concerns about using the wrong fuel. Is it okay to keep on going as is or do I really run the risk of damaging the car? Cheers
