I am considering selling in my 93 pathfinder for a 97 Landcruiser. I read somewhere that if your concerned w/gas don't consider getting this vehicle. I have to ask the following nonetheless. What grade of gas is required? Our premium prices (91 octane) are at $2.35 per gallon. I understand that the tank is 25 gallons and most get 12 miles to the gallon. Does the manufacturer allow 87 octane and if so has anyone noticed a loss of performance? I really want this SUV however I don't want to end up with buyers remorse.
