Warranty non-denial

Turbo problem. Verbally told warranty may be problem because I used non approved oil. I asked all future communication be in writing. That was a week ago. No word.
Car lease ends a week from now.
My understanding is I need a written denial of warranty coverage with reasons. Is there a time limit to receive a warranty denial letter?

    The warranty may in fact be suspended and you aren't alone in dealing with this. There has been a lot of information shared about how to choose products that meet the vehicle specification and just what you really had to do in order to service the engine correctly. Using a product that claimed to meet the dexos specification but wasn't approved for it was dancing with the devil. Sure many oil companies claim (claimed) their products are "equivalent" when they really are/were not. They post claims they will guarantee your engine above and beyond any warranty. They preach the Magnusson-Moss act warranty requirements. But at the end of the day when problems like this occurred it was always up to the vehicle manufacturer to step up and dealt with them even when it was clear that the way the vehicle was serviced was to blame for a given failure.

    So the real question that needs to be asked is, "With approved oil so easy to identify, why did you use anything else"? Stop and consider for a moment what would have happened to the next owner after this was turned in under the lease had it not already failed. Don't fault GM for not having made certain to service this at a level that satisfied their requirements, however if stories by "consumer experts" convinced you that using an approved product wasn't necessary then they are who you should be holding accountable.
