The big 30

that wont last long. im pretty sure running 98 octane on a stock truck engine isnt good. plus by the time you factor in the extra cost it wouldnt really matter if you used 87 and got 25mpg or if you got 32 out of 98 because they prolly equal out.
plus 87 is alot more avalible than 98. id just run the 87.
