Regular or Premium for a 2005 V6 manual 2-WD

Hi,

Been seeing in some frontier forums that you can use regular gas on a V6 Frontier. Planning to get a manual transmission Crew cab.

Any recommendations out there so once I purchase I know which gas to use?

thanks

The Nissan owners manual says 87 octane is all that is required but you may see performance gains with 91 or higher. For the most part, I run 87 octane in my V6 and it runs great. Once and a while, I'll fill it with Mobil Super+.

I have been running 87 octane in my '05 LE KC for 8 months and I have never had even a slight case of preignition.

I ran some pretty extensive, albeit non-scientific tests on the use of premium vs. regulas gas in the 4.0 V-6; 93-octane produced no significant gains in either power or economy. My truck, with very mild mod, produces over 235 rear-wheel horsepower (almost 300 at the crank) on 87-octane fuel, and gets over 22 mpg on the highway. Why waste money on premium?
