In my 2010 Lexus IS 250 I recently filled a close to empty tank with premium 91 octane fuel. How many miles should I expect on a tank? It said 325, and that seems low.

Thanks!

Been discuss in a lot of threads it comes down to how you drive and where you live. Not every one going have the same mpg.

just like guy above said. Varies. expect anywhere from 15-30mpg . lol i know theres a big gap there but really depends where you live, if its hot or cold, if you have hills or flat land, if you do mostly city or highway.... type in mpg on is250 in search bar and you can find many threads on it.

Also, keep in mind that mileage in the winter sucks due to gas stations using different blends for the cold weather. I'm getting 23MPG on my IS350 AWD in the winter when I normally get 26MPG. Do a Google search and you'll see a ton of articles on this.

I get 200 miles per tank on the 350 with 100% stop and go driving in the city.

I usually average about 300 miles per tank if it's 75% freeway and 25% city

I get a combined 25 mpg. I do mostly highway driving though and get up to 30 mpg in the winter and up to 33 mpg in the summer.
oh and when I top off I usually see 340+ for the tank

Same mpg here with all-city driving with a IS350, although the car's currently displaying 14.3 mpg.

This all makes me feel good, my old car used to get 5-10 mpg less than what others seemed to get. I dont think Ive changed my driving habits at all and now I seem to be on the high end of the average with the IS.
