Made a mistake last night???
I just recently purchased my TL and I made a mistake last night and put a half a tank of 87 in the car because I am so used to putting in 87 in my previous car. My question is do I need to wait until I use up the 87 in the car before I put 93 in the car?

its fine, the other half should be premium making it about 90 octane, fill it up with some more 93 octane and it'll fix itself out. Just don't rev too high and you'll be fine.

i did that too,. my friend filled up my gas tank cuz he owed me money and he put regular unleaded gas instead of premium. i didnt get mad cuz it was an honest mistake since he drives a honda civic.

Thier is not problem running 87 may cause detonation. Most of this time this is not true though. Your engine will not die b/c u poisned it with 87. I have put 89 since the first day, and the car runs perfect.

The reason for this is the TL has a high-compression motor. 87 or 89 will causing knocking, the motor will retard the timing, but there still will be some knocking.

Funny you mention that. Before I bought my TL I had a jetta turbo diesel. I pull into a gas station in Jersey, where they have to pump your gas for you. I pull up to the diesel pump and I ask the attendant to fill it up with diesel. He fills it up and I head back to my house in PA. All of a sudden my turbo stops responding. I go to my buddys garage and ask him to look at it. Turns out the asshole at the gas station put kerosene in my car. The engine burned so hot that it killed my turbo. Took me about 6 months to get it back to normal because I had to go through my insurance company.

I got my TL from a BMW stealership, and I got them to show me the gas receipt
. But yeah, the first time i filled up the first time I told them "Fill up regular please" (since I had a corolla before the TL). halfway through the fill up I told the guy to stop the pump and continue the rest with 92Octane

I ran 89 for 4 months straight, IMO the MPG was exactly the same (based off the trip computer). The only reason I think you would use more fuel is if you drive harder to make up for the lost power.

I put 87 in fearing that I wouldn't make it to the next gas station which was 3 to 4 miles away.. and I had already had the gas light on for 2+ days... so I put in 1 gallon of 87...

put in 3 gallons of 87... went home and said sigh.... on the way there... car started shaking WHILE IDLE .... DON'T DO IT DON'T DO IT....

ive had those gas problems before i let my friend drive my car and told him dont forget to fill it up and he put regular in by mistake, the whole tank..... my check engine light came on and stayed on for about a week.... but as soon as it came on i called him up and asked him what kind of gas he put in & low n behold he had put regular gas....
make sure u put some gas treatment and stick to premium, and youll have a whole lot less problems...i know from experience

I think the dealer puts the lowest octane in. I just ran out of my first tank (the one the dealer gives you) and I wasn't sure what gas to put in. I read the manual and discovered it is 91. So now I have a fresh tank of 93. It feels like it is running about the same, maybe a bit better. I think it's due for a fuel system cleaning anyway. I doubt that this was a service given to the car.
...oh, the point of my post: During the first tank, there was a semi-strong vibration felt through the steering wheel at idle. I'll see tomorrow morning if this is gone with the new tank of 93. Hopefully it is. I would hate to always have that vibration. A few friends have already criticized the car for it.

Dude, you will be fine. Late summer of '08 during the "gas crises" in the south, every station I went to was out of premium. I had to 87 just to get where I was going. I did this for at least 3 tanks and I didn't sweat it at all since I had no choice. Soon as I got back home, I switched back to 93 and all is well.

is that a question or statement? Either way, running higher octane gas on a car designed for low octane will really do nothing to harm it, it might slightly add power since the car will detect less knock and bump up the timing.

I dono, I seemed to get the same mileage based on the trip computer, but really it is too hard to tell, there are too many different variables to determine the exact gain when moving from 89 to 93 but 13% seems high to me.
