Let's just say I had a bad day. It was storming like hell, I was travelling, and an unfamiliar Mobil station had Unleaded pumps with Green labels and handles. Was on about 1/4 tank, accidentally topped up with gas and drove 150 mi on the highway before it started running rough. It stalled as I pulled into a dealership that was on the highway and would not restart. No engine light but the code reader picked up some ignition related fault code. Filed an insurance claim and preparing for the worst. I am worried how this will go down and what the future will hold for this engine, the shop is talking about "flushing" everything- even if they get it to run I can't imagine just flushing the systems will address all of the unseen damage to piston crowns, HPFPs, injectors, etc. What if the head gasket goes at 50 k mi (34k now)? How would you handle the negotiations with the insurance co here? I have requested they inspect cylinders with a borescope, beyond that I am not sure what to do. I don't want to be constantly having future related failures. Wondering if I need to just get rid of it, although it will cost a fortune to replace it. Maybe I should buy an extended service contract and get out before 100k mi (the powertrain warranty wont cover anything but internally lubricated parts) Thanks for any advice or experience offered on this subject.
