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
