Gasoline contaminated w/ diesel

[surffisherman]

My wife's filled up her 2005 tahoe last Thursday night and it immediately started knocking and running bad. I thought she got a bad tank of gas with water to added a bottle of ISO heet on Friday. We drove it over the next two days with it running bad and smoking and burned about a 1/4 tank out of it. Low and behold our local news caught on to the story and it turns out that the delivery driver got the tanks backwards and dumped diesel into the 87 octane and put the 87 into the diesel tank. My wife's tahoe is currently at the dealer getting the tank drained and new fuel filters. The oil company's insurance carrier is in touch with us and will reimburse us for the expense but here is the catch:

"They want us to sign a waiver before they will cut us a check saying that any future problems with our car is not related to this incident."

I can understand their position to some extent because I know there are people that will blame everything little thing that goes wrong with their car on this incident but I also do not want to sign away my rights if something related to this incident does come up in the future.

So if there are any GM certified mechanics frequenting this board, I would love to get some feedback on any possible damage the diesel may have done. Or was this a non-event and I can just sign this waiver and be done with it?

Diesel in a gasoline engine causes no permanent damage, but you will have to drain all the diesel fuel, which includes not only the tank, but the fuel system as well. I would go ahead and do what you have to do to get the company to cover all costs of the drain and fuel system flush.

I would definitely change some spark plugs along with fuel filters, oil, and oil filter. JMO

I sure would not sign that waiver. I'm not a mechanic but it just seems kind of funny that they want you to do that. What if you have a problem in the future and it can be proven that it was due to running diesel? If they don't pay for the current issues without you having to sign the waver I would contact an attorney or at least your states attorney generals office or the better business bureau.
