Did your friend sign a blank work order? They can't just magically spring an $800 repair on her unknowingly without her consent. They legally can not do any repairs or teardowns without her consent.
Here is some information:
----DOING THE PAPERWORK
By Law, the auto repair shop must provide a written estimate before doing any work. Ask if there is a charge for the estimate. After you have received the estimate, feel free to go to another shop for a second opinion.
A written estimate must include the total estimated price for parts and labor for a specified repair or service. The estimate must also itemize the parts to be used and the method of repair. The repair shop must stick to the method of repair and the parts listed unless you agree in advance to any changes.
In addition to the total amount, the estimate may itemize the parts to be used and the method of repair. If so, the repair shop must stick to it. They may not legally substitute parts or change the repair method without your consent.
The technician will ask you to sign the estimate/work order, which gives the shop permissionto proceed with the work. If you want any of the parts returned to you, be sure to say so when the technician gives you the estimate.
Before you sign, be sur eyou understand the work the technician will do. Your signature means you agree to pay for the repairs up to the amount specified. Do not sign a blank work order.
Newer cars often need a diagnosis before repairs can be done. A diagnosis uses procedures established by the auto manufacturer to determine the cause of the malfunction. The estimate may cover the cost of the diagnosis alone, or the cost of diagnosis and repair.
If some of the work will be done at a different shop, it must be noted on the written estimate or work order. For example, auto body shops sometimes have auto glass shops replace damaged windshields. If so, the shop must get your permission, unless you cannot reasonably be notified.
------------
Diagnosis, Then Repair
After the technician finishes the diagnosis, the shop will call you to describe the repair work that is needed and to give you the estimated cost of the labor and parts. The shop representative will ask for your permission to do the work as described.
You do not have to give your authorization over the phone, but if you do, the shop must make the following notations:On the invoice
The name and telephone number of the person who gave the approval, and the date and time it was given. After the repairs are completed, you may be asked to sign or initial the following statement on the final invoice:
"I acknowledge and oral approval of an increase in the original estimated price."
Instead of verbal authorization, the shop may use fax or e-mail approval. If so, a copy of your e-mail reply or fax authorizing the repairs and/or cost must be attached to the final invoice.
----------
When the repairs cost more than the estimate
If the technician later determines that it will take additional work and will cost more to fix your car than the original estimate, someone from the shop must contact you, describe the additional work and cost, and get your permission to proceed.
You may designate someone to authorize additional parts or labor for you. The approval must be noted on the estimate and invoice.
------------
The Teardown Estimate
For some complex problems, such as a transmission failure or an auto body repair, the shop may have to take your vehicle apart to give you an accurate estimate. This is called a “teardown.” Be aware that there may be a charge for a teardown, even if you don’t have the vehicle repaired.
A teardown estimate must include the following:
* Notice that the vehicle may not be able to be re-assembled. * The cost, which includes reassembling the vehicle, and replacing gaskets, seals, and other parts destroyed in the teardown * How long it will take the shop to reassemble the vehicle
After the teardown, the technician must write a revised estimate for the repair that shows:
* The estimated cost of the parts and labor for the needed repairs * The parts needed for the recommended repairs
The shop will then contact you for permission to do the repairs. If you decide not to proceed with the work, the technician must reassemble the vehicle within the cost and within the time stated on the teardown estimate.

If You Have a Problem
If you are dissatisfied with the repair work, ask to speak to the service manager. It is often easiest and quickest to resolve the matter directly with the repair shop.
Keep these tips in mind:
* Know your rights, as defined by the Automotive Repair Act * Remain courteous and calm. * Explain the problem accurately, and explain what you think would be a fair settlement * If you are willing to negotiate, say so * If the problem cannot be resolved to your satisfaction, tell the manager you intend to file a complaint with the Bureau of Automotive Repair

Honestly, if Midas did everything by the book that huge bill should not have come as a surprise. If they just overnight did the work and never informed her of the cost, time, or parts to be replaced then she can not be legally bound to anything she did not approve ahead of time.
Read through that link and have her understand her rights. However, if she signed a blank work order or gave them permission ahead of time by signing an $800 estimate work order then she's screwed.
Good luck on getting this sorted out and let us know how it turns out.
EDIT: Also, unless your friend is driving a turbo PT Cruiser GT their low octane fuel use theory won't apply.
