440 miles = 700kms
on a ~75L tank (or 20US Gallons)

10.7L per 100kms is the fuel consumption then - which is not too bad.. better than the so called rated average at time of selling the vehicle..
or 22MPG

Its a very decent number

Id say you are getting an outstanding miles per tank @ that rate. The best ive ever gotten was 370 on a road trip. I get about 18mi per gal now, but im kinda always playin around. I drive my vvti like its a 5spd. I also have 3.76 gears.

I can now definitely see where you got the 440 miles number. I don't know but just recently I have approached this number. I gassed up in St.Mary, MT and commenced a hard aggressive drive up and down (track style almost) Going to the Sun Road with 4 Passengers. Drove back up through Waterton aggressively, lots of speed variation and huge elevation changes. Got back to Calgary and did a bit of city driving as well.

I ended up with 420 Miles to my full tank, which I was definitely pleased with. I think if I was driving like a sane person on a "normal" road, with good alignment (need to get that done) I could definitely get to the 450 mark. Good mileage for a big heavy V8!

Also, not to take it too off center but I traveled with 4 on this trip and no one complained about the back seat, apparently its actually quite comfortable! Go figure!

I am a 98 SC4 VVti btw.

464 on full tank g400, snaped a pic of it too.

SQ400

I have been getting between 400-425 on all my road trips at of my 93 SC400. I bought her back in Dec. of last year and have logged a bit over 23,000 miles on her to date. That has been a pleasant surprise to me, Not to bad for a V8 of it's age.

id be happy getting 439 in my car i do more city driving and i can squeeze 300-350 out of my car. ill be doing 3hr highway drive so and ill have changed the fuel filter before then and just did a ton of maintenance including spark plugs wires, yadda, yadda, yadda so i would be ecstatic to see a highway improvement

edit: also have a k&n filter in my stock air box and i will be doing the BFI intake to see if it helps

I'm gonna do my best at hypermiling my next tank to see if I can improve on the 439..

that's really good. I drive 50/50 and the most I get is 21mpg flat.

I was avg about 325 - 350 a tank with mixed driving, and the CEL on for EGR. I did an egr delete and with mixed driving hit almost every time 400 miles a tank now. This is going about 70 - 80 on the highway and about 50 everywhere else. And occasional bursts of acceleration. Dont know if I am just an exception but just my experience. I have a 96 sc300 with 220k miles.
