yet another mpg thread!

[jhbhatia]

Sorry about this..wanted to see what could be possibly be wrong.

On my 1mzfe camry, i'm getting just about 320 gallons on a full tank of premium gas 93 octane; all miles are highway...if i'm driving city, i'm lucky if i get 200. (lets' keep the premium versus regular wars out of this thread).

* Car has 77K miles.
* Air Filter was replaced 2 months ago
* EFI service done 2 months ago
* Denso Platinum Plugs replaced in June 04 along with Toyota ignition wires
* Fuel filter was replaced at 60K miles.
* No added weight - no stereos, etc.
* Tire pressures checked, all good...(rotated and balanced 2 months ago as well).
* Nothing specially in performance mods...other than air filter, but i mentioned that earlier...

What other things you guys recommend, that i didn't think of normally....

The most I can get out of a full tank of gas on regular is 260 miles and this is with a 4cyl..... About 65% city 35% driving. I dont know if its the fact that the car has almost 230k miles or what, but I wish I got better gas mileage. My Altima is a 3.5L 5sp and it gets much better gas mileage.

320 miles to the tank isn't all that bad. My 5sfe gets 330 miles every time i need to fill up again, and this is all highway driving. How many gallons are used up? Aslo, it depends on your driving styles and habits. I tend to rev the engine and floor it, major no-no's for conserving fuel. The most I ever got was around 400-420 miles, but this was ultra conservative driving.

i used to get about 300miles per tank but lately i've been getting less.... mainly cause gas cost so much and 20$ doesn't fill up the tank like it used too

[jhbhatia]

OK - keeping in mind same driving habits, i get 300 on my 1mz camry and 450 on my 5s solara. Its not like it take the revs high at all...no jack-rabbit starts and 60 seconds at most warmup in the mornings.

I average 750km or 470 miles (26.2 MPG) per tank with my 4cyl camry. I would say 65 to 70% highway with cruise at 120 to 135 km/h (like 75 to 85 mph)

I do not driveuntil the fuel tank is empty though. I refill at 1/4 tank, so there is a bit of weight there (28 lbs estimate) .

I do have a bit added weight, such as 14" steel wheels with snow tires at 37psi , all year round, an extra 1.5 gal gas in a jerry can and 1 gal of windshield washer fluid, squeegie, snow brush, mobile office, etc.

Some things that help are that I cleaned my points in the engine bay and replaced grounding wires with 4 gauge copper wire.

Painted the exhaust headers with
The heavier tires means that momentum is retained while cruising, so the engine does not have to work as hard accelerating all the time.

I also use fuel additive like Lucas Upper cylinder lubricant as directed with all gas I use, and in the engine 0W-30 or 0W40 motor oil.

i am at 250-300 with 90% in town driving.
my old 87 camry i frove mostly highway, even with 250k i still averaged 25-30 mpg. usually i would get 100 miles per 1/4 tank.
the most i ever got was 478 miles from completely full to coasting into the gas station, that was in town and highway driving

How could one go about checking this? I know roughly what it does, but not where it is on the 5SFE.

Thanks

That doesn't sound too bad actually. With 90% city driving, I get 18-20mpg. I leave the overdrive off if going under 40mph, and turn it on when I'm going 40mph+ on the freeway or a highway. If I tone down my driving habits I'm sure I could improve my gas mileage. Going from 1st gear to 2nd gear, the AT usually shifts at 2500-3000 RPM. If I can let up on the gas and let it shift at 2000 RPM I'm sure it would be better. In fact.. I should try that since I just filled up gas. I also need to check the tire pressure.

Gas is expensive here! $2.33/gal @ Costco for premium unleaded.

I don't know about other States but Oregon requires oxygenated gas (10% ethanol mix) from 1st Nov through Feb. It affects performance and decreases economy. I know my bike engine hate the shit.

[xpeed]

My highest was 541 miles on a full tank. No refuels or anything. I see that as a greatest achievement for a camry and all PLEV cars out there! But then, I'll never get it over 440+ miles ever again. Just seems impossible now due to rain and racing the clock to school.

I was averaging 24-25 mpg on my 97 V6 during the summer - overdrive always on, 75% hiway miles at 75-80 mph. This winter it has dropped as low as 21 mpg.

[04sev6camry]

i got about 24 mpg in my 3MZ-FE on the way back from vegas, and that was even racing some monte carlo on the way back to, but i whoped him every time he tried. on the way up there i got 26mpg i think.
oh by the way, gas is down to $1.97 for premium
ive get about 400 miles on long trips (depends on how fast i wanna get there, 100+ mph kills the mpg), normally i fill up at 300-350 before me fuel light comes on

Damn, only $1.97 for premium! In NY it's $1.93 for regular.

hmm i used to get around 260-300 at most out of my 4cyl camry, but after changing the O2 sensor (15mins or less), so far i'm estimating around 450-500miles per tank! So far i've driven the car 64miles running on just 1/8 of the tank!(around 2.3gallons), thats 27.8MPG!! and i often FLOOR the gas!
