2 questions about my new Truck.

It says 87 octane is that cool and all does it run any bettet with high octane in it? So far ive ran 92-93 in it.

Also is there any quick way to figure if i have the 26 or 36 gallon tank?

1) I would run the lowest octane possible w/ no pinging.
2) Run it 'til the low fuel light comes on and fill 'er up.

I run regular in my 04 with no problems. I believe the long beds have the 36 gal. and the short beds have the 26 gal.
