I'm thinking of getting rid of my tahoe for for something better on gas and look at a is300 how is the car on gas and do you have to use Premium gas in it

Thanks for the help

Yes. And it gets pretty crappy gas mileage at that.

I get ~19 mpg city + Hwy with mostly < 3K rpm shifts.

I'm getting about 17.9 on average according to the app on my phone. About 85/15 highway/city spirited driving but traffic usually sucks so stop and go, sometimes idling for more than 5 minutes because of construction on an offramp. A51 intake using K&N filter and Lsportline exhaust, otherwise stock enginewise.

Mine gets 20 mostly city. Guess that's not too bad

I get around that too. The 2JZGE has some a nice torque band- which I'm sure is at least one reason the gas mileage is not the greatest.

That's not that bad,so what would happen if a person didn't use premium gas would it hurt the motor

If you don't plan to use premium gas, DO NOT BUY AN IS300 it's obviously not for you.

I just did a 2000 mile trip this weekend, including hours of idling (car shows) and I averaged 24 over it all.
