That's pretty amazing mileage, seeing as how the car is only rated an EPA 33 mpg highway!

 

^^ You really be careful with how you fill you vehicle, look at the owners manual to see how they suggest filling. The reason I say this, you could accidentally mess up your emissions system by having fuel flow into the evap canister or whatever else is inline with your filler neck. With my truck they suggested no more than 3 clicks.

 

If you think that is amazing there are others that get over 40mpgs on a regular basis.

 

Yes, there have even been a few folk who have had to replace the fuel evap system due to overfilling their Scions.

Keep in mind, too, that if you pump cold underground-stored gasoline into your vehicle, on a warm day the gas can easily expand enough to overflow into the evap cannister and ruin it, requiring replacement.

For some reason it seems a little bit easier for this to happen with the xA, but the xB can have a problem, too.

DON'T overfill the tank, especially in the morning with a warm day coming, unless you plan on burning off all the excess before your fuel system backs up like a flush toilet.

The intake for emissions is at the top of the filler hole - open the tail light door on the inside left of the hatch. I think it runs out the filler before it gets to that pipe. I also get my gas well away from where I end up (out of state) so I always drive 10-18 miles after filling up. It can take as much as a gallon after the first click because of the restrictions in the filler pipe just before the pipe enters the tank. It really needs a bigger tank.

 

Im bad about topping off my tank...I sure dont want to ruin my fuel evap system, nor do I want to over tax my fuel pump by running the tank down to fumes.

I'll be happy with getting to and from work monday thru friday, which is about 435 miles...I've gotten to 454 miles so I think 435 on a regular basis (without topping off) is a possibility...Im still tinkering with engine mods, tire inflation & acceleration, its really taking a long time to figure out what works best.

 

If 400 miles + range isn't enough you could always add a hitch and pull a small trailer with a 50 gallon drum of fuel stapped to it. You could even have a fuel pump mounted to it so you could hit a button and fill you tank from the drum while you are driving down the road. That way you could drive non-stop for about 2,400 miles (50 gallons plus about 10 more gallons already in the tankX 40 MPG) Heck you could also have your oil changed at the same time you have to stop for fuel.

 

OOPs, I forgot to take into account the weight of the trailer and 50 gals of fuel. You should only get 35 mpg with the added weight so your range would still be 2,100 miles.

 

yeah thats the ticket...

 

No the oil changes are already done for 150,000 miles with the synlube. The gas tank issue due to the trips I take sometimes requiring me to gas up a couple of times a day and if I didn't top off and run really low the usable capacity would be about 9 gallons. Scion wants you to get gas at 1/4 tank and not top it off so that reduces it to about 8 gallons. A second tank that can be filled when the gas price is low or you find that cheep gas station or filled for that long trip so stopping for fuel at some remote location is just a safety factor that I would like to have. A trailer carrying fuel is a fireball or theft ready to happen. A second 10 gallon tank could save $1-$2 bucks every time you find a cheep gas station and save your life if you got stuck in some remote location. A friend ran out of gas on a trip to Colorado and killed his van fuel or engine not sure which.

 

When I fill up- its only to the first click- NEVER over fill.

 

Let me guess, he ran out of gas before Greenriver? There is a 100+ miles strectch without a gas station there

 

WOW! I am lucky to get 325!

 

I was thinking the same thing.
Back in the "Olden Days", when I'd drive back to Colorado to visit my family, I'd be sweating that stretch, since my '70 Challenger R/T got MAYBE 10-12 mpg on the highway.
Between worrying about gas AND breakdowns out there in the middle of No Man's Land - in a time LONG before cell phones - there was never a chance of me falling asleep at the wheel, anyway!

 

I am still young and love to be the first person off and ahead at the light to get into the fastest lane and to beat the light ahead of me so this is not a possibility for me because my mindset is MPG compared to time at home or working on my project vehicle. Yes by driving that way I am only saving a MAX of 5 minutes so I think in the near future my goals will change and I hope that I can join the 400 club but for now I will settle for my 300 max~!

 

Maybe the trailer idea was bad but you could engineer a way of mounting a plastic fuel cell that could hold up to 15-20 added gallons of fuel. Plus it wouldn't weight that much more when filled.

 

Hey, I can definitely relate - I'm older, not dead! Just check out some of my other vehicles in the signature area below if you think I don't still have the same interests in speed that you do!
However:
A. I'm presently driving 3,000-3,500 miles a month commuting, and every last cent I save (especially now at around $3.30/gal. for gas) getting better mileage is money in my pocket for more mods for one of the cars.
B. It was a blast just seeing what kind of mileage I could squeeze out of the ol' Box. There was nothing too serious about the whole exercise - I was having fun working at it!

 

so anyway... finally got my injen sri with aem dryflow installed. like i said, first thing i did when the airbox was out, ripped the snorkel off and punted that thing (dont worry i kept it). turns out you really have to twist it but i didnt quite have enough room to do it.

anyway, after the first tank with my intake, i got 35.5 mpg... that doesnt sound too impressive, but about 80% of those miles were hwy traffic or street driving. before the intake, the most i got was 36 (all hwy running speeds).

so... an intake would help too, as long as the sound doesnt prod you to floor it all the time. self-moderation is the key!

 

Amen, bruddah!
Glad to hear its working for you, too...

 

I need your opinion on something Box (and of course anyone else who wants to chime in)...we've seen that taking the snorkle off and/or adding an intake can improve MPG, wouldnt it also follow that adding the right header and exhaust could improve mileage even more? Thanks!
