For three months there has been a high (and rising) volume of calls from owners experiencing EXTREME POOR QUALITY FUEL...
There is no discernible pattern across North America.

I strongly recommend diesel owners begin carrying a quart bottle of Cetane Boost additive.

Symptoms are abrupt, after filling the fuel tank:
* Massive smoking.
* Vile stench from the exhaust pipe.
* Stumbling or nailing.
* Moderate to extreme power loss.
* Some cases the fuel was bad enough to shutdown the engine.

My personal experience with this issue.
bad smelling fuel, Gag, gasp, choke
