After Service Issue

[hobba]

Update: I recently was made aware the BP gas stations in FL do not put ethanol in their blends. Ethanol was pointed out to me by Toyota as the potential cause of my 10 mpg loss of mileage. With Ike coming to visit FL in a few days, I fueled up with BP gas. While I only took on 5 gallons, I intend to buy BP gas for the next few tanks to see if ethanol is the cause of the problem. I'll report back to POG with the results.

I’ve experienced the same problem. The MFD has suddenly dropped from 51 (I am driving a lot on the highway) to 45 right after the 60K service at local dealer in July and has never gotten back to normal. I have tried many things but don’t help. I've tried Chevron instead of Shell, tried premium gasoline, and tried to drive slower. The tire pressure is at 35psi.
I am planning to contact Toyota for help but very disappointed to know that Toyota Corp. can’t also do much about it.

If you have read my posts in this thread and have the same problem, you have my sympathy. I anticipate a call from Toyota corporate some time this month to follow up with me on this problem. They claim they have received similar calls from around the country, however, not all vehicles seem to have the problem judging by the lack of activity related to this topic on this site.

I'm beginning to wonder if it isn't a computer or electronics problem. I used to get over 100 MPG on the first pip. With this tank of gas, I got 35 MPG on the first pip. My dealer went over the electronics on the car twice and claim everything is to spec.

Its too early to tell if the BP gas I put in has made a difference or not. I will have to run a few tanks through to see.

Its frustrating.............

Latest update: After talking with Toyota corporate offices for the past few months, they have now recommended the cleaning of the fuel injection system. They made arrangements for my local dealer to perform the service at no charge and I had the work done on Oct. 20th. The gas tank was nearly empty at the time and I filled up with BP gas, ( with 10% ethanol). I have only put about 150 miles on the car since the service was performed, but mileage and MFD seem to be working as beforethe problem started. I got 112 miles on the first pip which is close to the 120 miles on the first pip I had always gotten before the problem started. The MFD currently reads 43.2 MPG which is within the range I was getting before as well. Obviously its too early to tell if the fuel injection system cleaning solved the problem. I plan on driving at least 2 or 3 tanks of gas before declaring the problem solved. Toyota wants me to call them after that and let them know if I feel this has solved the problem or not. They are anxious to know since they report others with the same problem as mine. Finally, I want to thank Toyota for their support and my local dealer, Ft. Myers Toyota for their help. I will report back to PriusChat members after I run those additional tanks through the car.

What kinda crappy gas were you buying to have fouled the injectors?
