I just picked my new 08 Crew Cab 4wd LE long bed today. Great so far but just getting to know the truck. I checked this site out and thought I did some extesive research and decided on this truckmover the Tacoma and knew In was going to sacrafice a little fuel mileage, but this inn my opinion is more of truck. I traded my low mileage F-150 thinking this will haul what I needed and save some gas at the same time.

One big thing I missed and was shocked when I read the manual is that Nissan reccomends 91 octane fuel. Here in NC all premium is 93 and the cost 20 cents plus per gallon. Has anyone ran regular or mid grade in their vehicles and what has been the result? Do you see much performance difference? Any knocking? and would using different fuel violate the warranty? Any feedback would be greatly apreciated.

Manual definitely says 91.  I didn't realize that and had been running 87 and had been getting 20 mpg.  I've been running 93 since and mileage has gone down consistently to 17 mpg.  Go figure.

Manual only says you may notice a decrease in performance (I didn't).  It doesn't say not to do it.

Not to throw anymore fuel on the fire, but looking at www.nissanhelp.com (not sure if that's officially affiliated with Nissan Motors, Nissan NA or not) when looking at the specs for the 05/07/08 Frontys, when you scroll down to the fuel economy section, it states Recommended Fuel: Regular Unleaded
