North American spec Mobil 1 is junk compared to the European spec stuff, not sure about the extended life stuff.

AFR is nothing if the timing is too far advanced and the gas octane is too low.
The fuel will pre-ignite before the top dead center of the stroke and twist the rod, eventually ejecting it out. If tuned on 93 and you put 87 in good bye engine, There is a reason the factory tuning and timing is not the maximum limit of the engine for a safety factor and reliability.

"I have a tune and aftermarket parts, so I'm going to blame my engine failure on my oil."
EL OH EL. Post Hoc ergo Properter Hoc indeed. I'm not a gambling man.. would still put all my chips on the tune. Bad gas is a probability but statistically improbable, even in the event of "bad gas" most cars don't lunch their engines, they just run very poorly. So, throwing a rod, even if bad gas was involved is still a fault of tune that was incapable of adjusting for the knock from said gas, not mention you would have noticed a poorly running engine well before you lost it (with gas bad enough to cause a failure). Sounds like a meeting of 2 flame fronts before TDC, and over a period of time it lead to a ping ping ping ping... BOOM. Probably only happened within a small window of the RPM range so that's probably why it lasted as long as it did. Had this car been tracked or was a track only car it would probably would have failed much earlier.

Bad gas is the last thing that will cause a problem... its way more of a problem if the oil isn't changed frequently enough and gas builds up in the oil degrading its ability to lubricate the engine properly.

pretty sure it was not related to oil, but could it be the failed valve? isnt they updated valves for 2015 model ? or maybe the guy over rev it?

I was speaking to this guy on my facebook the other day, From what he had told me hes running the open flash tablet tune and has full bolt ons. He claims to have changed his oil every 3k and he recently changed it before his engine blew, like 1k miles before.

If we actually wanted to figure this out (not that we can), the FIRST thing to do is determine what is meant by "thus causing it to throw a rod."
This can mean more than one thing. Did it "Spin a rod bearing"? - Lubrication Or did it "break a rod"? - detonation/over-rev Or did it "break a piston" resulting in a "thrown rod"? Far too many details missing for us to determine cause. |

Unless you remove the RPM limiter, won't happen under accel, although not good to just sit there and bounce it off the limiter.
Hence my suggestion of a money shift, you're in 5th and want to go to 4th, but accidentally drop it into 2nd and let out the clutch before you notice. Mechanical overrev, BOOM. |
