any really good gas saver ideas?

[campfire9]

I have only used 87 octane in my 99 V6 Auto from the day I purchased it and will get between 18-20mpg around town and 25-27 on the highway at 75mph and I use a/c 100% of the time. Can't stand wind noise and the dirt that comes in with window down.

Remember that in 99 the epa ratings were always about 2 mpg higher than actual because of the way they tested cars. No accessories on and doing 55mph on the test stand in no wind conditions. Naturally some people can get the epa rating sometimes but imo not consistently.

Why pay 20-30 cents per gallon more for gas that is not a benefit to you when keeping your engine clean as stated above and driving in a reasonable way will get you as good as it gets.

^ lol.

maybe he'll sell it to you...blaK, name your price for that 380mpg solara!!

name your price if jerry dosent follow thru

Haha, nah but seriously I do drive slow.
I get about 300 when I have driven it hard.
93 gas, k&n, air pressure, oil changes on every 2k

Why do you change your oil every 2K? Especially if you drive like a GRANNY, you shouldn't need to change it that often, waste of resources. that is, of course, unless it takes you 5 months to go 2K.

dont drive with windows down.
dont overuse that overdrive button or dont use it at all (if u have auto)


and pretty much whatever else everyone else said on here.

DONT put in Acetone in the gas tank. yeah itl increase mpgs from what i heard n read but it'll f up your engine.

Jeff, the overdrive button helps with MPG.

^^^^When I use the overdrive button on my parents' Camry, @45-50mph the engine speed increases to 3000 rpm even with feathering the accelerator. I don't get how that can actually help save gas.

Could be how you are driving it.

ok, dont know what the chip did to the mpgs. it was on the car when i got it. probably did good tho.
i use 93 octane, for one, MY manual says its required, and second, the car runs really bad with anything less. its runs great with 93.

what i meant by asking this topic was what are the best aftermarket upgrades that i can do to get better mileage. I just bought the Greddy Twin exhaust kit. looks great! just havent installed it yet. i am sure that it might help with mpgs

^ if your car had 93 gas since she was born( bought) hehe thats why it runs horrible on lower gas, its used to the higher oct gas. theres really no major upgrades, jsut a k&n filter with proper maintenance.. MY solution is WALK

fastsolara-please check your pm.

Thanks

I meant overdrive on places OTHER than the highway.

lighten up your car, tire pressure , air filter, oil, easy on lead foot, that will save you a few bucks at the pump.

In my time on the board, there were no chips that had any measurable effect on the toyota ECU's. That's why everybody went to the SAFC for power enhancement.

Having said that, modern ECU's are adaptive to your driving style. Try disconnecting the negative battery terminal for several minutes to reset the ECU fuel and timing map to the base map. Then, maybe see how 87 octane works on easy driving style.

[campfire9]

Right on FLETCH. I would wait until I needed gas and only fill the tank to 1/2 with 87 octane and then reset the ecu. The car should run just fine.

[Fletch]

Fastsolara, my bet is the cans are too far downstream to have a noticable effect on power of fuel economy on a NA motor. Not to say it won't look, sound cool and be a bit more responsive. The y-pipe is restrictive on our platform, especially for S/C cars.

Making sure the air filter is clean should help a bit.

other than selling this car and getting some 4 cyl honda, whats the list of the best things i can do to get closer to that 30mpgs?

The very best thing you can do is drive like there's an egg between your foot and the gas pedal. Very gentle slow starts save a huge amount of gas compared to jumping on it every time you start. Let off the gas earlier than you currently do when approaching a stop.

Group your trips so the engine only has to warm up once. Gasoline engines run much richer (use more fuel) when they're cold. Don't sit with the engine idling to warm up. Just start, give it a couple of seconds for oil pressure to come up then drive away (gently). Anytime you're sitting still you're getting zero miles per gallon.

Keep the speed down. 45 mph is probably the most efficient speed for your car since that's the point where it kicks into overdrive. The faster you go the more road and wind resistance you have to overcome and mileage falls as a result.

Make sure your tire pressures are at least at the recommendation or a couple of pounds higher to reduce rolling resistance.

Roll windows up and turn AC off to reduce wind resistance and power robbing drag on the engine.

Check your trunk. Are you carrying 'stuff' you don't need? A few pounds of junk can add up to noticeable fuel consumption.

Of course make sure your engine is properly tuned

And finally, unless your owners manual specifically says to use higher octane fuel you'll get much better mileage using regular. Contrary to what some might believe, 'premium' fuel does 'not' produce more power than 'regular' it only resists pre-ignition better in high compression engines.

Without getting into the chemistry higher octane fuel is more difficult to ignite than lower octane so takes longer for the flame path to grow and start pushing the piston downward. Essentially it's like retarding the timing. Lower octane (87) fuel ignites more easily so (unless you're hearing pre-ignition) is more efficient in engines made to burn regular.

If you want the best mpg, keep the car stock.

You have a performance chip?
