Im getting 14mpg...i gave the car a basic tune up, about 2 weeks ago and still getting the same mpg....how many mpg are you guys getting?

 

im getting 13 unfortunately but im 85% city so that plays a role in mine.

try and look up seafoam and change your sparks? seafoam helped me

 

Maybe you should stop driving!

 

Do you drive mostly city or highway?
What did your tuneup consist of?
What is your Average MPH?

I drive 50/50 and get 22mpg. With the MID saying Average MPH, about 25mph.

 

Wow I'm getting 17 in the truck that I traded my TL for, and it's just as quick.

Mixed driving I would get about 23-24 in my TL, if I kept it mostly on the highway I got as high as 32-34. I used a Scangauge II to keep track and also kept a log every time I filled up so I know these numbers are correct.

Are you flooring it from a stop every time? Are you using the cruise on hilly roads? The gas pedal isn't an ON/OFF switch, try to keep it off the floor.

 

The average MPH from the MID is a huge predictor of MPG. Remember when you're idling at a light or in a drive thru you're getting ZERO mpg. The best way to improve mileage is to change your commute if there's an option. For example, if I take the coastal route to work I get 17-18 MPG because there are more lights. If I take the highway, I get 19-21 because there are fewer lights and the car can hum down the highway for a few miles and get 30MPG as it's humming. In the former scenario the average MPH is about 20 MPH and the highway case it's about 26MPH

 

Two word man, Shell Premium!!!

It took about 4-5 fill-ups after using Exxon and Hess Premium for a while, but I'm getting the best mileage since I switched over!!

 

I get 19mpg w/ac on while driving 50/50 city/interstate. There are alot of hills here so im guessing it would be higher if I was on flat land.

 

I STRONGLY agree!! I use only Shell premium and I get 20 in the city and thats with a LOT of stop and go's. I get 28-30 on hwy if I keep it under 80. I drive the car pretty hard too so I'm quite happy to get 20mpg's in the city!!

 

^^
Ditto on the Shell Premium, have used it for nearly 10 years and have always had 20+ mileage in the city and about 31 highway!

 

My FX35, simply by nature is a gas pig, but not to to bad for a luxury crossover. Before switching to Shell Premium on that for instance, I was lucky if I could get 17mpg avgs around town. I live in a rural city area by the way. I might have been able to get 19 or 20mpg on long distance travel. These avgs were with 93 Octane Hess and Exxon Gas.

After 5-6 fill-ups, and yes, depending on how long and what kind of vehicle you have, it might take that many fill-ups with Shell Premium to get the crap/gunk gas out and see a difference, I was able to get 19 and 20 mpg on avg just around town, with 22-23mpg avgs on longer open highway/interstate trips!

I mean we are only talking a couple mpg difference but when gas prices get up to $3.50 and $4.00 a gallon, every little bit helps!

On my TL for instance, before Shell Premium, I was getting 21-23 mpg avgs around town, with 25-28mpg avgs on open highway/interstate trips/commuting. With Shell Premium, I'm now getting 26-28mpg avgs with 30-33mpg on open highway/interstate trips!

So you can see the big difference, especially with my TL!

Shell V-Power

 

check the pressure in your tires, they should be around 34 PSI COLD! Also remove any dead weight such as old papers, clothes, tools, etc that you don't use. Last but not least, use premium fuel from a top tier brand!

 

Exactly! I completely forgot about the tires. Great point man. If your tires are not inflated properly that can reduce your gas mileage too. I think the base TL is recommended 33 PSI Fronts/32 PSI Rears cold but I usually keep it 1-2 PSI's above recommendation so in the Spring/Summer I do 34 PSI Fronts/33PSI Rears cold and in the Fall and Winter I do 35 PSI Fronts/34 PSI Rears cold!

 

You know what also helps? If you have the factory navigation installed, hack your navi and install the trip computer (see the Acura Navi subforum for that). It makes you feel guilty when you accelerate unnecessarily. There's a current MPG meter as opposed to the average MPG you see on your MID. That should increase your MPG a bit

 

I'm not sure about the OP, but I don't have the tech package so didn't get that and only have the MID to go by. But my 2010 Max has it, and as you pointed out, I use that all the time to monitor and get good mpg because the gas pedal is so finicky and you only need to lightly touch it to keep speed up and keep the bar at 30+ mpg on the readout!

Forget about accelerating up a hill though, that bar shoots down to 0 mpg until you get up over the hill and level out. I wouldn't want to live in San Francisco !

 

These anecdotal experiences that claim shell to boost mpg are interesting, though a bit hard to believe, but,

enough to make me want to try

i will report back in a month

 

How do you know you are getting 14mpg?

full proof method: start trip meter after a gas fill up. Next time you get gas, divide the trip meter by the gallons you just put in the tank.

 

Well, as i am Canadian and too lazy to convert..

One thing i WOULD recommend. Top off the damn thing, when the gas nozzle clicks, continue to top it off. I can usually fit an extra 8 bux in it! And testing it.. When i took it out after clicking, id get about 490KM/tank.. When toping it off to the most gas i can get in it, i usually get around 620 KM/tank.. Dunno how many mpg that is though..

Anyone else experience this?

 

Topping it off isn't going to raise your mpg. It's just going to give you more miles per tank.

Besides, topping off isn't a good idea. Especially $8...Geez, that doesn't sound right to me.

 

I don't see the point in doing that.
There's a possibility you can ruin the Charcoal Canister.

 

^^ x2 on ruining the charcoal canister. Never top off. Once it shuts off, it's done.

 

You're also helping make your car heavier thus actually killing your MPG. 8 bucks of gas is like almost 3 gallons. Take 3 gallons of milk and see how much extra weight you're lugging around.

If you really are serious about getting the best gas mileage, search for the thread "the TL Diet" by Innacurate and see what kind of mods you can do to make your car lighter / more efficient. There are weights around / underneath you car that really serve little purpose that can be removed, not filling up all the way at the pump (1/4 tank at a time for me.. I fill up every 2 - 3 days) and of course.. do what is always obvious.. make sure your tires are properly inflated (a couple psi above is probably better and allows for a better smoother ride), make sure your fluids are changed in proper intervals (crankcase / tranny oil)for tranny oil use Amsoil.. shift manually at 2 - 2.3k. and I can't stress seafoam...

Seafoam was prolly the number 1 best 8 bucks I spent on my car. 1 can.. every few thousand miles...

1. 1/3 of the can in my intake (first time you do it, you should see a ton of smoke come out)
2. 1/3 in your gas tank (make sure you have less than a 1/4 tank left and run it till empty
3. 1/3 in your oil crankcase (make sure you change your oil soon after... no more than 100 miles on oil treated by seafoam.)

 

Remember, it is not necessarily a quick fix. It depends on a variety of factors, especially what type and kind of gas you have been using and how long you've been using it. It might take a little longer than just a month. As I said, on two of my cars it took 5-6 fill-ups with Shell Premium to begin seeing a difference. It takes time for the Shell gas to clean out all that crap gas junk from the exhaust system!

 

I used to get that much (14mpg)...then after a while I guess I subconsciously changed driving styles, and got my mpg to go back up to 18 or so...recently I've been doing a fair amount of highway driving so I have been at 20mpg.

 

Check air pressure on tires. 34-35 psi on the fronts, and 30 psi on the rears. Make sure they are cold when checking.

Replace your air filter if you haven't done so.

You could consider running synthetic oil, and synthetic tranny fluid. I stopped using Z1 ATF, and change over to Redline D4, and now I get about 1mpg more than I did before.

Change your driving style. If you drive mostly city, and push the car, it's going to get shitty mileage, just the way it is.

 

unfortunatly for me the nearest shell gas station is quite a drive off =\ wouldnt make sense to waste gas to get there and waste it to go back home

i stick with mobil gas premium or w.e was the highest octane.

i have seafoamed and that moved me up from 11 mpg to 13 mpg.

my car has nothing in it but me and a bottle of water. rarely have passengers

i drive AT but i rev the car up to 2k-2.5k rpms before i let the car shift its gears( or do it in semi auto) i can actually see my milage range jump pretty high (anywhere from 10-50 extra miles a tank)

im waiting on spark plugs for now and will try fuel injector cleaner (seafoam might have cleaned it up but just being safe)

 

How many miles do you have on the car? What did your tune up consist of? Other maintenance performed?

 

It doesn't have to be Shell specifically. I only mention it because it is the only top tier gas brand around where I live. If you use any of the top tier companies, you should see the same or similar improvement in mpg! Here is a list below with all the top tier companies right now!

http://www.toptiergas.com/retailers.html

 

63k miles i just got the car like 2 weeks ago but the previous owner did his due maintenece regularly at an acura dealership and did his oil changes every 2k miles.

anything else i might have missed?

 

did the previous owner give any receipts or records? Check the last time the Engine Air Filter was changed, as well check all the fluids in the engine bay to make sure they are filled properly. Someone changing their oil every 2k leads me to something odd...

 

Ditto.. I've been using Shell gas here lately only because it's on my way home from work. But I get maybe $15 at a time.

 

I can probably count on 2 hands the number of times I've pumped anything other than Exxon in my car. I have no idea why, but I always had to pump Exxon, and only when there were no Exxons around or emergencies would I pump anything but Exxon. I get about 22-23 mpg in mixed city/freeway driving and get about 29-33 mpg on highway trips. I'm about to hit 142,000 on the odometer. I'm tempted to see if anything changes if I went a month with a "top tier" gas like Shell. My guess is not much would change, but hey, I'm all for experimenting.

 

SEAFOAM. Use it in your oil and fuel. It's like $7 at Advanced. Best $7 I ever spent.

 

Not a smart thing to do. That will damage the Emissions equipment. There is a VAPOR canister and when you try to top off the car it will fill this up and damage it. Two clicks is enough and stop filling it.

 

Geez, I had better switch to Shell and do Seafoam and see a mileage increase of 4-6 MPG. Maybe someone can answer a question-With all the electronics on the car to keep the A/F ratio correct, how can changing gas and doing Seafoam increase the mileage? I know I'm being sarcastic, but these fuel mileage threads become quite annoying after a while.

Over on the Grand Cherokee Forum some will report that they see 24 MPG on a 4500 lb 4 x 4 V-8 Jeep, and that is rediculous. Got to sit back and swallow hard.

Sorry, I guess my low blood sugar is kicking in!

 

to be real: a good cleaner like redline SI-1 or seafoam in the gas tank, I personally like 1 can to just under 1/2 tank ~8 gallons, will remove combustion byproduct left behind by E10 gas--that stuff is murder on our engines
the result:
clean piston tops, intake valve backs and edges, fuel injectors and the cat WILL make a differance in a computer controlled car

So will having the valves adjusted properly- to feed that air fuel mix correctly at the right amount and time
4-6 mpg increase?- must be a dreamer. 1-2 mpg easily obtained

Use of one of these products is equal to those 6 tanks of shell or chevron
both have good cleaners in `maitenance dose` amount from the pump which will clean stuff out over 4-6 tanks -not quick/instant cleaning dose --

tire pressure- see max cold pressure at what weight marked on tire sidewall
compute actual weight on tire and use percentage to calculate optimal pressure for actual weight
example max cold psi 50- car weight 80% of max allowed tire load, reduce pressure by 20% from max cold = 40
add 1-2 psi from there to suit
that works for most tires- especially low profile aftermarket tires
will get even tire wear across and best mileage and handling in most cases

Stock setting is for comfort not milage

 

I can see where the skepticism can come in Turbo. The problem with these threads and mpg is that there are just so many different factors that affect what kind of gas mileage people get, it hard to know if a different brand will indeed improve their mileage, especially if they drive the car hard or with a lead foot, for instance.

I can only speak from my own personal experience on 3 separate vehicles, that each time I've calculated by hand the mpg after each fill-up, I am getting much higher reading consistently with Shell then I ever did with Hess, Exxon, or BP gas. I don't go by what the MID in the car says is the avg and always do it by hand and go out to the furthest decimal place when possible. I even have been able to go to the same station and same pump consistently, as to reduce the variables as much as possible, but of course you can never reduce them all!

I know not every where in the country there are Shell stations, but I think if anyone what to try any of the top tier gas brands, you should see at least as small improvement. Again, the improvement or lack of improvement seen will of course be controlled by the variety of factors that affects mpg regardless of the gas brand one is putting in!

 

In response to the 2 threads above, you can put a 90% clogged air filter in your car and you won't see a deterioration in MPG, performance yes, but not MPG as the AF ratio will still remain the same. Less air being able to be passed through the filter will in return lower the amount of fuel injected into the cylinders to keep the AF ratio the same.

Ive used Shell premium in our modified RX7 Turbo over the last few years because the station is near our residence, but before that, the car saw Exxon or Getty and the MPG has never changed, stays right around 18.5/19 with the driving we do.

Food for thought would be that if Shell did indeed increase the MPG of vehicles, the manufacturer's would certainly be the first to know as that would definitely help the CAFE.

Guess I gotta close with if it works for you that's all that counts.

 

Well Honda, along with GM, BMW, and a couple other companies on that link I gave many posts ago approve of top tier fuel use and are the ones that came up with the stringent standards for top tier fuel, which those companies submitted their gas, and based on testing, were awarded that status. My Acura dealer has recommended it as well, but I suspect that Honda or any of the other car companies can not just come out and publicly endorse one specific gas company because there would be huge outcry from Exxon, BP, etc etc that there isn't proof to that and there gas is just as good, etc etc. That is why Honda, GM, BMW, and the other car companies apart of this top tier gas requirement/system only recommend those top tier companies be used in their products.

My only problem is this, if Exxon, BP, and the other non-top tier companies gas is so good and just as good if not better than Shell, Chevron and the other top tier companies, why won't they submit their gasoline grades for testing? I mean that is the bottome line, all they would have to do, is submit their gas for testing to prove they match the requirements/criteria and clearniness of the top-tier companies but they refuse. To me, that means they are hiding something. If they didn't have something to hide, then they should have no problem submitting their gas for testing. Just some food for thought as you would say ! Thought something that has always annoyed me with Exxon/Mobil is that they are always whining and complaining if anyone ever calls them on something, like price gouging, bad gas, etc yet they always have an excuse why they do that and as I said, if any car company came out and blantly recommends Shell or Chevron, or who ever, you know that Exxon/Mobil will be the first in line to whine about it. Just submit your damn gas for top tier testing and their would be no problem!

Again, as I pointed out before, you haven't noticed a difference in your RX7 but I or anyone else have no idea how you drive that. Plus, its a sports car so that can change its dynamics/performance characteristics that affect fuel consumption compared to a sedan or cross over vehicle? I'm just stretching here mind you because so many factors affect mpg.

By the way, I can't really talk about Shell Regular because none of my 3 vehicles use that so I can only speak for the Premium grade gas between the brands!

 

Some guy in a marketing department somewhere is going to get a nice bonus because of this thread.
