Do you have any trouble codes? Is the hood shut? Those are the common factors to the truck shutting off.

People don't surprised me anymore.

Every 10K at minimum. I personally do every 7500.

I buy the walmart blue peak def and never had an issue. I wouldn't be afraid of the high volume ones either however.

I haven't, but it looks like something I wouldn't trust on my $50K truck. Also, you can't even flash an EcoDiesel via the OBD port. So I would say it's just a fooler anyways. Go with something tried and true. GDE, PPEI, etc..

Welcome to the forum! Sound like a streak of bad luck as hit you. The electronic throttle control code is random, and I'm not sure I've seen one fix or solution yet for it. Some have the problem, and some do not. For your other issues, all new to me personally. Let's hope the dealer can get...

Welcome Scott! You can find the official TSB info here: http://www.ecodieselram.com/forum/threads/tsb-18-078-16-engine-oil-viscosity-upgrade-and-flash-enhancements.1178/ Many posts (and opinions) on the forum about it. Read up and ask any questions you may have!

The Duramax/Allison trucks are a great trucks, and solid. I've had 3. :D

Good to hear!

It's not a bad idea, if you plan on keeping it "stock". As in, no tuning, etc.

My father had a 2000 year with the 5.3L back in the day, it was a great truck as well.

It's not like it's costing them money, they are being paid for the warranty work. After they admitted a lie, I would of been hot for sure.

It's crazy how some trucks are just bad news.

So they told you it was bad fuel, and now they're saying it isn't?

Welcome to the forum! We're glad to have you here.

A scanner, or monitor like the Banks IQ or Edge CTS2 Major auto parts stores will clear codes for you as well free of charge.

Welcome to the forum Grim! Sounds like you have a great plan already. Stick around and be apart of the community, a lot of good info here.

That's great info @Nutt . You should have done a write up and documented it for us :D. I have a feeling you won't be the last guy to have this problem.
