Common denominator is the owner. With very few Eco being blown and you blow 2 in a short time I'm sure they are thinking you abuse your truck. I'm sure that's not the case as I have driven mind hard from day one and have 45k miles. Maybe you have a perfect storm of conditions that don't like ecoboosts. They are looking at stats and the stats are probably telling them there's a better chance of winning the lotto once than having 2 motors blow within 5k miles.

For you guys that think 91 octane is low octane, at high elevation it's not. In fact most high elevation cities only sell 87 as the high octane fuel.
If the truck is stock it should live through what he's doing to it, even with low octane fuel it shouldn't blow a rod through the block.

As far as me being hard on the truck goes.

Yep. You bet I am. I also maintain it like a top. If something is broken or some service needs to be done I have no problems doing that. It sees lots of high speed highway, mud, and bad gravel roads.

I've been rackin my brain here and mechanically all that stayed original the first time the engine went was the trans. I'm not sure about sensors either.

I'm pretty sure the owners manual says the truck can run on 87 all day long. 91 is the highest octane I can "always" find. It's seen the odd tank of 94 too.

All I know is something is wrong when after 30 hours of driving engine 2 is done.

If there's some kind of break in period for a new motor that's fine and good but an owner should be notified of that in writing I'd think.

Is it possible they didn't actually replace the original engine?

Something about this story is fishy.

If you assume the chance of a total engine failure is 1/1000, then the chance of them happening back to back to the same owner is 1/1,000,000. I'll believe it when I see pics.

Lol. The truck is 11 hours from me. Ill get right on that for ya.

Pm me your phone number and ill text you the 2 pictures I took the first time. One shows my truck being loaded on flat bed and the second is the pieces we picked up from underneath it.

I have the paperwork at home explaining what was replaced so I doubt it. It was a catastrophic failure I was told. When I called roadside the operator had a wow moment when she was reading off what had been replaced.

Come to think of it I could send pictures to anybody nice enough to post em. I'm on my phone. Will also take photos of paperwork. As far as pics showing the second blow up like I already said you're sh!t outta luck.

Sub'd. This is crazy. Sorry you have to go through. Trade that Eco crap in for a 6.2! :thumbsup:

There is no way in hell I'd be as calm as the OP.

Wasn't the last Blown Eco from Canada as well
