To the people using 91/92 octane why don't you buy a water injection kit as well



unless you have forced induction I don't see a need...

If the vehicle could gain even 1 mpg using the higher octane, you can bet Toyota would have done it that way so their MPG numbers would be higher. Can you even imagine that it would get 3 mpg better? They abosulelty would love to have a 19 city and 23 highway rating out of their 381hp 1/2 ton. 87 octane period.

We referenced a really nice explanation from Car Talk regarding different levels of fuel octane -- here's the link to Car Talk's nice explanation and our explanation of how it relates to the Tundra.

Car Talk's explanation (pics and everything):

Our Premium v. Regular Tundra Tip is that premium fuel typically does include some fuel system cleaners, so it might be worth running a tankful every once in a while assuming you're too busy or too lazy to buy some fuel system cleaner at the auto parts store.
