My Tank AVG depends on city:18-21 and highway:25-28 driving around 60-70mph like everybody said. My AVG is about 21.5mpg with probably 40% city and 60%highway

shell premium v-power and highway driving at 73 mph gets me about 31 in my IS350. Yes I make long drives and have it down to the exact mph haha. but word to everyone... NEVER BUY MARATHON GAS!!!! i promise you that you will see a reduction in mpg.

I average about 280 miles from a full tank on my 06 is 350 which is rouugly anywhere from 16-19mpg. I drive about 60 freeway 40 streets. I have been highly considering a pressurized fuel system cleaning from the dealer. I really do not trust those additives as I hear they eat away at some of the internals.
Any suggestions?

Yes, I was surprised how fuel efficient the 350 is. It's better than advertised on the car sticker (of course YMMV -- haha see what I did there?).
After 29k miles, I get around 370 miles on a fill up.

I get about 24-27 on the highway. Could probably do better if I slowed down a little bit. Basically though with mostly city driving I get around 300 a tank, and only about 360-370 if all highway. Keep in mind I have the AWD so it's a little heavier.

MPG really depends on how you drive your car. I have a semi-heavy feet and I gas it pretty hard when I change lanes or merge onto the freeway.

my 06 is350 fueled with chervon 94 octane gas and around 130,000km... i average 10-13L/100km which is i guess 18-23mpg and that is when i drive like a douchebag... best i got was 8.9-9L/100km average which is around 26mpg and that is when i drive smooth and light on the gas...
