yup, that's how it always is.Thanks for all the replies. I feel more confident. People will complain more if something goes wrong rather than if something goes well. Wifey drives a Honda Accord as of now but with two kids with car seats she wants a third row seat and she loves the Infinity compared to the other third row seat SUVs. We are hoping to go test drive one this weekend.
I didn't know the 3.5 was a sports engine. I do agree with you and I will be using 93 for now.I've driven Infiniti's since 2006, and I always purchase 93 Octane. The 3.5 is a sports engine, and I believe you get the best performance if you use the higher octane, and maybe even better gas mileage. Some will disagree with me, but why would you spend $50,000 or more for a nice vehicle, then put cheap gas in it. Seriously, its only a dollar or two more per tank. I traded in a 2008 G35 with close to 100,000 miles on it. I drove it for 6 years, and never saw any diminished engine power over time, or had one bit of trouble with it. They claim the QX60 is a bit too heavy for this 3.5 engine, so why would you possibly want to cause any more strain on the motor with the 87 Octane. That's just my opinion, but I prefer to protect my investment.
