I use 87 octane gas, have had it since 8/14/10 and have not noticed any problems with using regular gas. I average @ 16 miles per gallon in the city. The ride is quiet and compliant. This is a good value for your dollar.
Ive had this SUV for couple of months now and so far no problems what so ever. Been off roading several times and matched performance those from Xterra and FJ cruisers. Plenty of power to TOW, because of durable and reliable v6. Really quiet on the highway.
Love the pathfinder. Have had it for 7 months. We traded in a toyota sienna, when looking for a new car, realized that we still needed the third row on occasion. I was surprised at how smooth the ride is. Not at all what I had expected. The only downsize is gas mileage. Around town get only 16 - 17 miles per gallon. On the positive side, took it up skiing and managed to get 22-23 miles per gallon.
I'm really glad I decided on the Pathfinder. I looked at the Explorer, 4Runner, and Pilot, however the Pathfinder suited me best. It was nicely equipped and has lots of power. The ride is firmer than the explorer and the 2nd row has less room, however my teenage boys say they have plenty of room. The gas mileage is on par with other SUVs of this size, but you are recommended to use premium gasoline. The keyless operation has taken some getting used to. Overall, I am very pleased with the purchase.
