I get 30 MPG on the highway and around 19-20 MPG in Toronto city traffic (which is 95% of my driving unfortunately lol) using my little 9 year old 3 liter. The best I've ever seen it was on a very long road trip to the middle of nowhere I got something like 36MPG.
It is going to be stopping and going that kills fuel economy particularly on the V8, once you're moving it barely has to break a sweat.

i still dont get why everytime i turn the car off and back on after some time, the needle has dropped even lower EACH TIME. is this normal? i mean I can actually say it moved by 1-2MM each time between starts. can't be normal because I haven't seen this happen in any other cars i have owned...
also, do you guys think these fuel mileage extenders help? like those small eco fuel saver shots you can buy?

My '06 has about 85k on it now and looking at my last 12 months I'm averaging between 20-21mpg on in town tanks and 24.5-25.5 on highway trips. 22.85mpg over the last 12 months, which was 46 fill ups. Only additive I've ever used is a bottle of Seafoam in the tank once a year. I've done this will all our vehicles since new and never had any fuel issues such as varnish or injector issues. 275k on one and 227k on another currently.

I'm guessing its just paranoia? which intake hose did u use to have the seafoam sucked up.
i know some goes into fuel tank and some goes into engine crankcase?

i have always wanted to seafoam a car. the problem is that I'm wondering how it will affect a motor that has never had the treatment and now at 150,000KM it is going to all of a sudden receive the treatment.

I'm going to be doing a tune up this up and coming weekend to my gs430. I normally drive my turbo Integra, which gets about 30-33mpg and my is300 gets about 25-28 I believe. But this is my first v8 and im not use to the amount of gas it can swallow. My gs430 has 54k on it and I don't think the plugs have been changed. Like suggested above I'll be cleaning and changing some items in hopes for improvements.
I guess the thing that brothers me is that I drive the car maybe once a week to work and mostly around a 5 miles radius when I'm home and I'm having to fill it up as if I'm driving it everyday of the week.
