Hi,
I was wondering which is the best octane to run in the Titan?

Unless you are experiencing some sort of engine performance issue I suggest you stay with the standard 87/89 octane that is recommended by Nissan. Going to a higher octane is only required if your engine cannot operate well on the standard octane and you experience "pinging" a sign of pre-detonation.

As the octane number goes up, down goes your bang for the buck. Octane additives are added to reduce the tendency to pre-detonate and this is usually only experienced in high-compression engines these days.

At least this is what I've learned over the years; besides, why pay more money for higher octane when you don't need it?

Yup. Your engine will only use what it needs.............

Regular is the way to go.

Yeah save your money so you can spend it on a better brand of sippin' whiskey! My personal favorite is Wild Turkey 101! Some days, I savor a glass of Makers Mark on the rocks for a change of pace.
