#785 of 1183 Help with fuel question.

I have a 1999 toyota camry LE, my car will only use premium fuel or the engine light comes on and will not go off until I refill with premium and ride almost to a half of a tank.(some time it stays on longer) Can anyone tell me why this is and how to fix this if it can be fixed. This is expensive, but it has always been this way.
Looking to reduce cost!

Have you taken it to a dealership and had them tell you which sensor is throwing the code to the CEL?

I have never gotten more than 1/2 gallon into the tank after the first click, pumping slowly but not trickling. A 3.5 gallon air bubble seems awfully large.

On my last roadtrip, I was experimenting with trying to mess around with fill error. It didn't work out the way I had hoped, but one of the things I learned while experimenting was the difference between 1st click off and absolute fillup on 3 different tanks of gas.
1.0, 1.1 and 0.8 gallons, 1st click to spilling fuel.
As a point of interest, I'll probably try and collect this information on all 3 cars now, just to learn something about the differences.

I heard that you don't want to spill fuel out, because it can get into the charcoal canister?
Yes, I can believe that it is a gallon that you can squeeze in after the first time the pump shuts off. 3.5 gallons - no way. Common sense tells me that a car manufacturer would not waste that much space. I can think of lots of other reasons that 3.5 gallons is not reasonable - I have never seen any proof of it. Troy's post above is good proof of about a gallon.
I will try to post my MPG readings this weekend.
#790 of 1183 MT's and bubble test report

My experience with the MT is that it gets a minimum of 5 mpg better than the AT at the maximum range (i.e., AT = just under 30 mpg, MT = 36+ mpg)
I have tried 9 different camrys, all automatic, and none of them have gotten 30 mpg on pure freeway.
I own a MT camry, and it never gets less than 29 mpg freeway. It is rated at 29 mpg. My AT camry is rated at 32 mpg, and averages 25-28 mpg. It does bounce around some, but not over 30, and not under 25.
The latest camry I have tried is a 2008, and it got just under 25 mpg on nearly pure freeway (normal driving speeds). I did a direct comparison with my camry, a 2004, and got 27 mpg. I found the 2008, to be a larger, more powerful, and responsive car, but it seems to use more gas.
On my latest tank "bubble test", I just did a short refill. This particular pump had very strong pressure. It clicked off at 8.5 gallons (~206 miles, 50% city driving, for an impressive 24+ mpg combined).
However, I was able to leak another 1.7 gallons into it (10.22 total, 20.22 mpg).
That's the smallest error I can remember - but one reason is that I couldn't even determine the error because of the high pressure of the pump. No fuel was spilled - I think there was alot more air left, but the pump just wouldn't pump slow enough.
I regularly get 2.5, 3, and even more gallons into the tank after the 4th click. At many different gas stations. 3 gallons is very common, for me, in my car - and the 8 other camry's between 2004-2008 that I tested. Others have reported a different experience, but that is mine.
One of my co-workers didn't believe it either - until he saw it (and looked under the car to see if there was a leak).

2002 Camry SE V6 Fuel
Hello I was wondering if anybody in here owns a Camry V6 between the model years 2002-2006, I was planning on buying one and just needed to know if it's alright to put midgrade 89 fuel inside it??? or will it just slightly decrease its power output?? or will it mess up the engine???
Thanks,

Do you happen to have the data? For example, are the Camrys involved from the same generation? Do they have the same engines in them? Are they of similar mileage, odometer wise? Do you have a few thousand miles of consecutive highway only tanks from each you can list here? Just highway mileage of course, perhaps a long trip on each? Odometer and fuel used on each fillup would be fine. You can't really include any commuting mileage to minimize driving "style" from the equation as much as possible. You can use Message#636 as a template on how to do this if you'd like.
The goal is to minimize some of the "optional" factors which can interfere with trying to get a clean highway figure. Any commuting whatsoever in particular. When dealing with data, its necessary to know the particulars to decide which lines up best to test the original hypothesis ( in this case the actual difference between MT's and AT's in Camrys ).

I own two AT Camry, 1997 Camry I am getting 35 to 40 MPG (Freeway at 65 Mile/ Hr) with inflated tires (40 psi).
For 2007 Camry 26 to 30 MPG with same driving conditions and style. I do use Scan Gauge for both the cars.

I own two AT Camry,
Would you happen to have city mileage readings on these two Camrys as well?
