Well its not an Armada but its still the same engine. I have a Titan and I posted this over on Clubtitan.org . I was always saying that I could not tell the difference between the 87 oct and the 93 oct fuel. So after the first 2 tanks of 93 I switched to 87. I have been running it for about 3 1/2 months now. Well about 2 weeks ago I decided to get some 93 because it was on sale same price as the 87. Well let me tell you after just a little bit i really started to notice a change. It felt a bit peppier and smoother. I know what your thinking you don't believe me but I tell you I can feel the difference. As far as I'm concerned I will keep getting the midgrade or the 93. Just my 2 cents.

This is a good question/thread, because I'm curious about this as well. I have put 93 in my Armada every fill up but one, where I put 89 in. Everything I've read, including the manual, says the engine was designed (and performance specs measured) running 87. With that in mind, you should be able to run 87, and have no loss of power or anything. However, what I really want to know is, would I gain power if I had my computer reprogrammed for 93, or is the Nissan processor self adjusting??
